双脉冲电源说明书
SMD 型数控双脉冲电镀电源使用说明书邯郸市大舜电镀设备有限公司使用本机前请详细阅读此说明书一、概述：脉冲电镀所依据的电化学原理是：当电流导通时，电化学极化增大，阴极区附近金属离子充分被沉积，镀层结晶细致、光亮；当电流关断时，阴极区附近放电离子又恢复到初始浓度，浓差极化消除。
SMD双脉冲电镀电源，即周期换向脉冲电镀电源（这里的“双”的含义指“双向”），它是在输出一组正向脉冲电流之后引入一组反向脉冲电流，正向脉冲持续时间长反向脉冲持续时间短，大幅度、短时间的反向脉冲所引起的高度不均匀阳极电流分布会使镀层凸处被强烈溶解而整平。
与单脉冲电镀相比，双脉冲的突出优点表现在：1、反向脉冲电流明显改善了镀层的厚度分布而使镀层厚度均匀，并因溶解了阴极镀层上的毛刺而整平2、反向脉冲电流的阳极溶解使阴极表面金属离子浓度迅速回升，这有利于随后的阴极周期使用高的脉冲电流密度，而高的脉冲电流密度又使得晶核的形成速度大于晶体的生长速度，因而可以得到更加致密、光亮、孔隙率低的镀层3、反向脉冲电流的阳极剥离作用使镀层中有机杂质（含光亮剂）的夹附大大减少，因而镀层纯度高，抗变色能力强，这一点在氰化镀银中尤为突出4、反向脉冲电流使镀层中夹杂的氢发生氧化，从而可消除氢脆（如电沉积钯时反向脉冲可除去共沉积的氢）或减小内应力5、周期性的反向脉冲电流使镀件表面一直处于活化状态，因而可得到结合力好的镀层6、反向脉冲有利于减薄扩散层的实际厚度，提高阴极电流效率，因而合适的脉冲参数会使镀层沉积速度进一步加快7、在不允许或少量允许有添加剂的电镀体系中，双脉冲电镀可得到细致、平整、光洁度好的镀层所以，镀层的耐温、耐磨、焊接、韧性、防腐、导电率、抗变色、光洁度等性能指标成倍提高，并可大幅度节约稀贵金属（约20-50%），节约添加剂（如光亮氰化镀银约50-80%）。
二、用途可用于镀金、银、稀有金属、镍、铜、锌、锡、铬及合金等；铜、镍等的电铸；电解电容的敷能；铝、钛等制品的阳极氧化；精密零件的电解抛光；蓄电池的充电等。

INTRODUCTION1.1 Hardware FeaturesThe SC4002 ALM is a universal input dual trip amplifier with isolated re-transmitted output. It can accept virtually every type of analogue input signal from millivolts to 40Vdc, mA, thermocouples, RTD’s etc. It produces 2 types of analogue output; voltage and mA source. It has 2 configurable trip action relay outputs, with optional latching operation and a variety of time delay options.The input value and setpoints can be viewed on a 4 digit display which is also used to display menu options when the unit is configured.The unit can be powered by any DC voltage between 16 and 36Vdc or 16 and 32Vac.The instrument is packaged in a compact 22.5mm wide enclosure which can be mounted on standard TS35 DIN-rail.1.2 Isolation DetailsThe SC4002 ALM has full 3 port isolation of 1000V between the Input Stage, Output Stage and Power Supply for functional reasons.2. UNPACKINGThe instrument should be carefully inspected for signs of damage which may have occurred in transit. In the unlikely case that damage has been sustained, DO NOT use the instrument, but please retain all packaging for our inspection and contact your supplier immediately.The instrument comes with the following items as standard: 1 SC4002 ALM Isolating Dual Trip Signal Converter1 SC4002 ALM User GuideIf the instrument has been factory configured the input and output details will be listed on the Serial number label on the side of the unit. If this label is blank then the unit will be set to its default configuration which is 4-20mA input and 4-20mA source output. Relay 1 will energise above 16mA, relay 2 will energise below 8mA. The other default options are listed in section 5.If re-configuration is required please refer to sections 4 and 5 of this manual.3.QUICK START GUIDEThis example shows how easy it is to configure a SC4002ALM with4-20mA Input, 0-10V Output, 0-100% on display.Before starting, make sure power supply, inputs and outputs are disconnected.

When all changes have been made, return to run mode from main menu by pushing and holding both buttons until OK is displayed then release.4.CONNECTIONSThe SC4002ALM is housed in a compact DIN rail mounting enclosure, with 16 terminals, arranged in 4 rows of 4 terminals. Two rows are at the top of the front panel and 2 rows are at the bottom. The relay terminals are on the top row and the sensor input terminals and the power supply and analogue outputs are on the bottom rows.The diagram below shows how to connect all the different input, output and power supply types.3 Wire RTD4 Wire RTD125R to 1K2 Wire Pot 1K to 100K3 Wire PotRELAY 2 18 Normally Closed 19 Normally Open 20 CommonPage 6 IIG-070101IIG-070101Page 75.CONFIGURING THE SC4002 ALMThe SC4002 ALM is an extremely versatile device which can support many different types of input. The unit is configured by turning the power off, selecting the internal switch settings required and turning the power back on. Further options are chosen using the menu system via the display.To open the SC4002 ALM, 2 catches just below the outer terminal blocks must be pushed in gently, one at a time. The front of the case can then be pulled and the unit will come out of the box.There are 2 switch banks, S1 and S2, a link L201 and a single switch S3 locatedSwitch S1, S2 and Link L201 configure the input type and range, and switch S3 configures the output type. The switch settings are explained in the next few pages. The diagrams refer to switch positions 0 and 1, with 0 being OFF and 1 being ON. This is illustrated in the picture above.Select the range from the table below and set Switch S1 to the required values.Then select the required setting from the table below for switch S2.Please note that PC Software is available to provide information onswitch settings for your input and output requirements.Page 8 IIG-070101Select the range from the table below and set Switch S1 to the required values.Then select the required setting from the table below for switch S2.Please note that PC Software is available to provide information on switch settings for your input and output requirements.IIG-070101 Page 95.3Millivolt (mV) InputSelect the range from the table below and set Switch S1 to the required values.

If this label is blank then the unit will be calibrated for 4-20mA input and 4-20mA source output. The side label also indicates the setpoints and relay operation. If these are blank, the default settings are:Relay 1 energised above 16.00mA (Set Point 1), Led 1 on when Relay 1 energised Relay 2 energised below 8.00mA (Set Point 2), Led 2 on when Relay 2 energised Input units are mA to 2 decimal places. Hysteresis is 0.2mA. Averaging is on, high burnout. Power on delay is 2 seconds; all other time delays are 0.5 seconds.6.1Main menu and Set Point menuTo access the set point menu push and hold both buttons until OK is displayed. These are the set point menu options, use raise and lower buttons to cycle through:1. SETPOINT 1 (sec 6.2)2. SETPOINT 2 (sec 6.2)To access the main menu a sequence of button presses must be entered.Push and hold in both buttons then:release raise, hold in both,release lower, hold in both,release lower, hold in both,release raise, release lowerThese are the main menu options, use raise and lower buttons to cycle through:1.

ON DELAY 2 (sec 6.10)To access the sub menu of one of the main menu options, use raise or lower to cycle to the option required then push and release both buttons. Change the parameter as required.To return to the main menu, push and release both buttons.To exit from the main menu and return to run mode, press and hold both buttons for 2 seconds until OK is displayed on the screen.After two minutes of inactivity from the front buttons when the main menu (or a sub menu) had been accessed, a timeout will occur and the unit will automatically return to run mode.In run mode, briefly pressing and releasing both buttons will scroll the input value across the display with the units. Any latched relays will also be reset.6.2Set Points 1 and 2, Hysteresis Points 1 and 2The default value for Set Point 1 is 16.00mA and Set Point 2 is 8.00mA, the default value for hysteresis points is 0.2mA. These values can be adjusted in their submenus, and a description of how they interact follows in the next section. Note that the value for hysteresis is the amount away from the Set Point, rather than a point in itself.6.3Relay 1 and Relay 2Each relay can function in one of the following ways (same options for relay 2).RLY 1 ON ABOVE SP1 (default for Relay 1)RLY 1 OFF ABOVE SP1RLY 1 ON BELOW SP1 (default for Relay 2)RLY 1 OFF BELOW SP1RLY 1 LATCH ON ABOVE SP1RLY 1 LATCH OFF ABOVE SP1RLY 1 LATCH ON BELOW SP1RLY 1 LATCH OFF BELOW SP1Latched relays are reset by pushing & releasing both buttons together in run mode.16.2 mA16.0 mA6.4Led 1 and Led 2The leds on the front panel can be configured in the following ways:LED 1 ON WHEN RLY 1 ON (default)LED 1 ON WHEN RLY 1 OFFLED 2 ON WHEN RLY 2 ON (default)LED 2 ON WHEN RLY 2 OFF6.5Output Span and Output ZeroSetting of the zero and span points is non-interactive, so each point need only be set once. Default output values are approximately 4-20mA or 2-10V out.A typical calibration sequence would be as follows:Display Action7.OUTPUT SPAN Apply full scale input.Press and release both buttons togetherSPAN ADJUST Press raise/lower buttons to adjust output value until correct Press and release both buttons together7.OUTPUT SPAN Press raise button to change main menu item to 8.OUTPUT ZERO8.OUTPUT ZERO Apply zero scale inputPress and release both buttons togetherZERO ADJUST Press raise/lower buttons to adjust output value until correct Press and release both buttons togetherWhen the unit is used to convert a thermocouple input it is important when calibrating to ensure that the thermocouple simulator employed is switched to automatic cold junction compensation and is at the same ambient temperature as the SC4002 ALM. Note that this is not always easy to achieve, especially if the SC4002 ALM is mounted in a warm cabinet. An alternative method is to use an ice-point reference and a mV source.6.6Input UnitsThe following units are available to represent the input signal.%, mA, V, A, mV, °C, OHM, blank (default: mA, 2 decimal places)The number of decimal places can be chosen to allow a bigger input range (with lower resolution) to be represented.2 decimal places (-327.68 to 327.67) or 1 decimal place (-3276.8 to 3276.7)6.7Input Span and ZeroIn run mode the front panel display shows the value of the input to the SC4002 ALM. Values can be adjusted to correspond to the full scale and zero scale input values used when Output Span and Output Zero were adjusted.The default Input Span value is 20.00mA, and Input Zero value is 4.00mA.6.8Relay TestThis option allows the relays and leds to be tested.RLY 1 OFF RLY 2 OFF (both leds will be off)RLY 1 OFF RLY 2 ON (just led 2 on)RLY 1 ON RLY 2 OFF (just led 1 on)RLY 1 ON RLY 2 ON (both leds on)Note that the unit will automatically timeout after two minutes of inactivity from the front buttons and return to run mode.6.9Output OptionsAveraging and burnout options can be selected. To restore the default values, choose DEFAULT VALUES then press and release both buttons to return to the main menu. From that point on, all values will have returned to defaults.AVERAGE ON HIGH BURNOUT (default)AVERAGE ON LOW BURNOUTAVERAGE OFF HIGH BURNOUTAVERAGE OFF LOW BURNOUTDEFAULT VALUESHigh burnout values are approximately 23mA or 11.5V.Low burnout values are approximately 0mA or 0V.Averaging is carried out using the following algorithm (a weighted average of the last eight readings, with each new reading every 20 milliseconds):New Average = New Reading + (7 x Old Average)86.10 Relay Time DelaysThere are seven time delays available. The maximum values are 1310.7 seconds, with a resolution of 20 milliseconds.16. POWER ON DELAY (default 2 seconds)After power on, relays cannot trip during this time delay17. OFF TO ON 1 (default 0.5 seconds) 20. OFF TO ON 2(default 0.5 seconds)The trip condition must be seen for this delay before the relay can trip (see picture below).18. ON TO OFF 1 (default 0.5 seconds) 21. ON TO OFF 2 (default 0.5 seconds)The trip condition must not be seen for this delay before the relay can reset (see picture below).16.0 mA15.8 mA16.0 mA15.8 mA19. ON DELAY 1(default 0.5 seconds) 22. ON DELAY 2 (default 0.5 seconds)Relay must remain tripped for this delay before being allowed to reset (see picture below).All 3 delays (or any combination) can be used at the same time if desired. Note that if the relay is tripped, both the on delay timer and the on to off delay timer can hold the relay in the tripped condition until both have expired (see picture below).16.0 mA 15.8 mA Set Point 17.INSTALLATIONThe SC4002 ALM’s input and output circuits are classed as Separated Extra Low Voltage (SELV). This means that they must not be externally connected to voltages exceeding 30V ac or 60V dc, nor do they generate voltages above these limits internally. Where a higher voltage input is required a specially designed DIVIDER unit can be used to condition the input signal prior to connection to the process input terminals.The SC4002 ALM unit clips directly onto ‘Top Hat’ (TS35) symmetrical DIN rail. Ideally, mounting orientation should be vertical. Good airflow around the unit will maximise reliability of the instrument.The use of bootlace ferrules is recommended on wiring terminations.Do not exceed terminal torque rating of 0.4 Nm – use an appropriate screwdriver. The unit can be removed from the DIN rail by sliding a small screwdriver into the slot at the rear of the enclosure on the lower face and gently levering the metal clip, whilst lifting the unit from the rail.8.TROUBLESHOOTINGThe SC4002ALM has some built in self diagnostic functions. Errors encountered will be displayed on screen.BURNOUT ERROR Check wiring connections of RTD or TC.EEPROM ERROR Stored data has been corrupted.

Presskey once2. Press Day3. Press Sel.4. Press key to enter Run ModeDisplay will show symbol above current time8th day schedule will be implemented on Thursday and run for 2days and then timer will revert back to normal programs.NOTE:If Sel.key is held down, it will scroll rapidly to 99 and back to 01To review the implementation scheduled, press key once.Display shows day of implementation and number of days holiday pro-gram will be active.Press key.To delete the implementation scheduled, press key twice. symbol disappears from display.On the day the Holiday Program is selected to begin, the 8th day program will be implemented. The display will show the Holiday symbol point, press once.s TROUBLESHOOTINGPROBLEM: Days are flashing, pressing any key does nothing except key turns output ON and OFF.SOLUTION: Time of Day and Day of Week have not been set. See “SETTING THE TIME”NOTE:This is the condition after a reset. If the timer is found in this condition after it has been installed, programmed and operating for a while, it may indicate that electrical noise or voltage transients have dis-rupted the microprocessor causing a loss of program information. Call 1-800-272-1115 and request that a no-charge “Snubber Filter” be sent to you to place across the input to the timer, which may solve the problem.A second, but very unlikely cause of loss of program is a power fail-ure with the backup battery low or dead. Check by disconnecting power and monitoring how long the battery keeps the time of day in the display.PROBLEM:Time of day was set while holding the key down,but days are still flashing.SOLUTION: Current day of week was not set while holding down the key. See “SETTING THE TIME”PROBLEM: It is 10AM and a ON program for 8AM was entered, but the output is not ON. Display shows the and symbols.SOLUTION: After programming, the timer does not “look back” to determine if it should be ON. Press the key (temporary override)to turn the output ON; appears in display. The timer will assume automatic operation at the next programmed event.PROBLEM: A program for 8AM Monday thru Friday was entered,but it will not accept it and CH1is flashing.SOLUTION: The ON or OFF was not entered as part of theprogram. ON or OFF must be selected.P r i n t e d i n U S A 082U S 010.97GRÄSSLIN GmbH & Co.

MT 82B 两线循环电源流量指示器说明书
1⁄8 DIN Economical Two-Wire, Loop-Powered Process Indicator with Liquid Crystal Display to ±19,990 or ±199,900, and 5 jumper-selectable decimal points. With the dummy zeros, the TX82B can thus be used to display the weight of heavy trucks in pounds or the volume of large tanks in gallons.Both span and zero are fine- tuned with precision 15-turn potentiometers accessible behind the lens. Coarse zero and span steps as well as the dummy right-hand zero are selected by opening the case and changing push-on jumpers.FM intrinsic safety certification is standard. Intrinsic safety certification allows the TX83A to be used in worst-case hazardous environments with no need for an explosion-proof housing, provided that an intrinsic safety barrier is used to limit the voltage and current TX82B Series that may be introduced in the hazardous environment. FM certification (USA) is for class I, II, III, division 1, groups A, B, C, D, E, F, G. The FM certification number is 2Y4A4.AX (3610).The TX82B is housed in a splash-resistant case and requires a depth of less than 100 mm (3.9") behind the panel. A splash-proof lens cover which meets NEMA 4 requirements is optional. Electrical connections are via a 3-pole male header connector on the circuit board and a mating plug-in socket connector with screw clamps, which accommodate wire sizes of 0.5 to 2.5 mm (26 to 16 AWG). These supplied connectors provide easy and reliable electrical connections and meet UL and IEC-348 safety requirements.TX82B is a 1⁄8 DIN-sized 2-wire current-loop indicator that is powered directly by 1 to 5 mA, 4 to 20 mA or 10 to 50 mA process signals, with no need for external power connections. This reduces field wiring costs and provides immunity from most electrical noise encountered in process-control environments. The 2-wire electrical hookup is easy via a plug-in screw-clamp connector, which is standard.The TX82B provides extensive zero and span adjustment capability for direct readout in percent or in engineering units for process variables such as pressure, flow, temperature, or level. A 12.7 mm(0.50") high LCD display provides 31⁄2 active digits for readout to ±1999, 2 jumper-selectable dummy right-hand zeros for display TX82B shown smaller than actual size.U FM Intrinsic Safety CertificationU Powered by 1 to 5 mA, 4 to 20 mA or 10 to 50 mA SignalU 2.5 Maximum Voltage DropU D isplay to ±1999, ±19,990 or ±199,900U 12.7 mm ( 0.5") LCDU 100 to 2000 Count Span AdjustU 2000-Count Zero Suppression or ElevationU Short 1⁄8 DIN CaseU Simple 2-Wire Hook-UpU Safe Plug-in Screw- Clamp ConnectorOrdering Example: TX82B, current loop indicator.SpecificationsSignal InputSignal: 1 to 5 mA, 4 to 20 mA or 10 to 50 mA (jumper-selectable)Linear Range: 0.3 to 50 mAProtection: Up to 200 mA forward, 1000 mA reverse current; forward voltage drop, max 2.5V Input Resistance: 50 Ω @ 1 to 5 mA, 12.5 Ω @ 4 to 20 mA, 5 Ω @ 10 to 50 mA Zero Adjust: -2000 to +2000 counts in 4 jumper- selectable ranges plus fine adjustment 00Span Adjust: 100 to 2000 counts with fine adjustment NMR: 46 dB, 50/60 HzCMR (Meter to Case): 120 dB, DC to 60 Hz CMV (Meter to Case): 300 Vac Accuracy at 25°CMaximum Error: ±0.1% of rdg ±1 count Zero Tempco: ±0.1 count/°C typical, ±0.3 count/°C max Span Tempco: ±0.005% of span/°C typical, ±0.015% of span/°C max Analog-to-Digital ConversionTechnique: Dual-slope, average-value Polarity: AutomaticIntegration Period: 100 msRead Rate: 2.5/sMechanicalCase: 1⁄8 DINPanel Cutout: 45 H x 92 mm W (1.77 x 3.62")Bezel Dimensions: 48 H x 96 W x 8 mm T (1.89 x 3.79 x 0.31")Depth Behind Bezel: 100 mm (3.94")Case Material: 94V-0 UL-rated polycarbonate Weight: 128 g (4.5 oz)Circuit Board Connector:Three-pole male header Cable Connector (Standard): Mating plug-in socket with screw-clamps for wire sizes 0.5 to 2.5 mm 2 (26-16 AWG)Connector Safety Ratings: UL and IEC-348EnvironmentalOperating Temperature (Standard): 0 to 55°C (32 to 122°F)Operating Temperature, Optional: -40 to 85°C (-40 to 185°F)Relative Humidity: 95% at 40°C (non-condensing)DisplayType: 7-segment LCDHeight: 12.7 mm (0.50")Symbols: -1.8.8.8.0.0 (31⁄2 active digits plus 2 jumper-selectable dummy right-hand zeros)Decimal Points: 5 positions, jumper-selectable Overrange Indication: 3 least- significant active digits blank。

5、使用注意事项
1、设备安装时应尽量防止腐蚀气体侵入。
2、设备到负载端的引线要粗而短（最好不超过2米），用多股铜线，正、负极相绞而用（即拧成“麻花状”到镀槽边时分开），这样可减小脉冲波形失真度，提高工作质量。

将阴极接上负载，调整电流试镀。数字表上显示的数字为平均电流，单位A。当电流调节过
大导致峰值电流超过最大值时，峰值保护”指示灯亮，设备无电流输出。此时应先将电流调节旋 钮逆时针方向拧到底， 然后按下“复位”按钮， 峰值保护”指示灯灭， 则可重新调整电流试镀。 注意： 任何情况下(即使直流)，数字表上数值均不得超过设备最大输出平均电流。
三、 特点
1、 设备兼有脉冲和换向的双重功能，为提高产品质量、节约原材料提供了强有力的手段
2、 机内装有同样性能的两组单脉冲电源，正、反向脉冲电流的参数均可单独调节，互不影 响
3、 设备可同时做为两台单脉冲电源使用
4、 设备主要功能为输出毫秒级周期换向脉冲（简称双脉冲）电流，另外，还可输出同等参数 的两组脉冲，两组直流，直流叠加脉冲，直流与脉冲换向，间断脉冲，对称或不对称方波交流电 等多种波形
“—”号去1。例如：设置TF为100ms,则选择TF的拨码开关数值为100;设置TR为10ms,则选择
TR的拨码开关数值为10。注意：TF和TR均不得设置零，否则“操作故障”指示灯亮，设备将不 能正常运行。
(5)、使用 开机前将面板上电流调节旋钮逆时针方向拧到底。打开电源开关，面板上正、反向脉冲的数 字表显示零，表明设备已接通交流“电源。

是在输出一组正向脉冲电流之后引入一组反向脉冲电流，正向脉冲持续时间长反向脉冲持续时 间短，大幅度、短时间的反向脉冲所引起的高度不均匀阳极电流分布会使镀层凸处被强烈溶解 而整平。与单脉冲电镀相比，双脉冲的突出优点表现在：
1、 反向脉冲电流明显改善了镀层的厚度分布而使镀层厚度均匀，并因溶解了阴极镀层上的 毛刺而整平
c、T是一个脉冲通断周期，T=ton+toff
d、TF是一组正向脉冲工作时间，TF=nT（n》是一组反向脉冲工作时间，TR=-nT（n>1）
e、TF+TR是正、反向脉冲换向的一个周期（一般TF>TR）
（2）、设备连接
参见面板示意图，从面板方向看，左边一组为正向脉冲，右边一组为反向脉冲。左边一组红、
黑接线柱分别与右边一组黑、红接线柱相连（此连接在设备出厂时已完成，接线柱在机箱背面） 。
4、 反向脉冲电流使镀层中夹杂的氢发生氧化，从而可消除氢脆（如电沉积钯时反向脉冲可 除去共沉积的氢）或减小内应力
5、 周期性的反向脉冲电流使镀件表面一直处于活化状态，因而可得到结合力好的镀层
6、 反向脉冲有利于减薄扩散层的实际厚度，提高阴极电流效率，因而合适的脉冲参数会使 镀层沉积速度进一步加快
7、 在不允许或少量允许有添加剂的电镀体系中，双脉冲电镀可得到细致、平整、光洁度好 的镀层
(6)、有关计算
a、正、反向脉冲频率的计算
正、反向脉冲频率f的计算方法相同，均由各自的脉冲通断周期T决定，即
f=1/T=1/(ton+toff), T的单位S。例如：ton=0.2ms,toff=0.8ms,贝U f=1/(0.2+0.8)x10-
2、 反向脉冲电流的阳极溶解使阴极表面金属离子浓度迅速回升，这有利于随后的阴极周期 使用高的脉冲电流密度，而高的脉冲电流密度又使得晶核的形成速度大于晶体的生长速度，因 而可以得到更加致密、光亮、孔隙率低的镀层
3、 反向脉冲电流的阳极剥离作用使镀层中有机杂质（含光亮剂）的夹附大大减少，因而镀层 纯度高，抗变色能力强，这一点在氰化镀银中尤为突出
则选择ton的拨码开关数值为2,则ton=2x0.1ms=0.2ms;设置toff为0.8ms,则选择toff的拨 码开
关数值为8,则toff=8x0.1ms=0.8ms。当Ton、Toff均设置一定数值时，为脉冲状态；当Ton、Toff
均设置零时，为直流状态。
(4)、正、反向脉冲工作时间的设置
正、反向脉冲的工作时间TF和TR均为1,2,3,……,9999ms自然数调节，拨“ + ”号加1,拨
左边一组红、黑接线柱分别接镀槽的阳、阴极，即完成设备的连接。 注意：此时两台单脉冲电源
串联，属短路接法。
（3）、正、反向脉冲通断时间的设置
正、反向脉冲的导通时间ton和关断时间toff均为
1x0.1ms,2x0.1ms,3x0.1ms,……，999x0.1ms,拨 “ + ” 号加拨“一”号去1。例如：设 置ton为0.2ms,

一、概述：
脉冲电镀所依据的电化学原理是：当电流导通时，电化学极化增大，阴极区附近金属离子 充分被沉积，镀层结晶细致、光亮；当电流关断时，阴极区附近放电离子又恢复到初始浓度， 浓差极化消除。
SMD双脉冲电镀电源，即周期换向脉冲电镀电源（这里的“双”的含义指“双向” ），它
