SOA PROTECTIONDESCRIPTIONThe L7800series of three-terminal positive regulators is available in TO-220ISOWATT220TO-3and D 2PAK packages and several fixed output voltages,making it useful in a wide range of applications.These regulators can provide local on-card regulation,eliminating the distribution problems associated with single point regulation.Each type employs internal current limiting,thermal shut-down and safe area protection,making it essentially indestructible.If adequate heat sinking is provided,they can deliver over 1A output current.Although designed primarily as fixed voltage regulators,these devices can be used with external components to obtain adjustable voltages and currents.12TO-3123TO-220ISOWATT22012313D 2PAKBLOCK DIAGRAM1/25CONNECTION DIAGRAM AND

TCA785参数规格书及应用

TCA785P规格书及运用TCA785是德国西门子(Siemens)公司于1988年前后开发的第三代晶闸管单片移相触发集成电路，它是取代TCA780及TCA780D的更新换代产品，其引脚排列与TCA780、TCA780D和国产的KJ785完全相同，因此可以互换。

目前，它在国内变流行业中已广泛应用。

与原有的KJ系列或KC系列晶闸管移相触发电路相比，它对零点的识别更加可靠，输出脉冲的齐整度更好，而移相范围更宽，且由于它输出脉冲的宽度可人为自由调节，所以适用范围较广。

一、引脚排列、各引脚的功能及用法TCA785是双列直插式的16引脚大规模集成电路。

它的引脚排列如图1所示。

图1TCA785的引脚排列(脚朝下)各引脚的名称、功能及用法如下:引脚16(VS)：电源端。

使用中直接接用户为该集成电路工作提供的工作电源正端。

引脚1(OS)：接地端。

应用中与直流电源VS、同步电压VSYNC及移相控制信号V11的地端相连接。

引脚4(Q1)和2(Q2)：输出脉冲1与2的非端。

该两端可输出宽度变化的脉冲信号，其相位互差180°，两路脉冲的宽度均受非脉冲宽度控制端引脚13(L)的控制。

它们的高电平最高幅值为电源电压VS，允许最大负载电流为10mA。

若该两端输出脉冲在系统中不用时，电路自身结构允许其开路。

引脚14(Q1)和15(Q2)：输出脉冲1和2端。

该两端也可输出宽度变化的脉冲，相位同样互差180°，脉冲宽度受它们的脉宽控制端引脚12(C12)的控制。

两路脉冲输出高电平的最高幅值为VS。

引脚13(L)：非输出脉冲宽度控制端。

该端允许施加电平的范围为-0.5V~VS，当该端接地时，Q1、Q2为最宽脉冲输出，而当该端接电源电压VS时，Q1、Q2为最窄脉冲输出。

引脚12(C12)：输出Q1、Q2脉宽控制端。

应用中，通过一电容接地，电容C12的电容量范围为150~4700pF，当C12在150~1000pF范围内变化时，Q1、Q2输出脉冲的宽度亦在变化，该两端输出窄脉冲的最窄宽度为100μs，而输出宽脉冲的最宽宽度为2000μs。

StellarNet便携式拉曼光谱仪性能介绍与参数一览

StellarNet便携式拉曼光谱仪性能介绍与参数一览型号HR-TEC-785的拉曼光谱仪是StellarNet生产制造的一款大受欢迎的拉曼光谱仪，特色在于它的参数非常广泛波长范围00-3200cm-1，同时整合整套拉曼光谱系统价格实惠，是大多数想购买拉曼光谱仪，搭建拉曼光谱系统的理想选择.StellarNet提供了应用于200-3200cm-1的各种便携式拉曼光谱仪，可以快速识别各种液体，固体或粉末样品。

其中785nm 激光是拉曼光谱选择的最常见波长。

因为这段波长是红外激光在拉曼效率，荧光效应和吸热这3种反应中，依旧能保持平衡的波长。

同样，785nm激光器通常比其他频率便宜，从而使整个光谱系统的价格变得较为经济实惠。

Raman-HR-TEC-785拉曼光谱仪是stellarNet大受欢迎的拉曼光谱仪，包括针对785nm拉曼调谐的增强型CCD阵列检测器和先进的检测器透镜组件，可在长时间曝光时实现超高灵敏度。

StellarNet拉曼光谱仪Raman-HR-TEC-X2-785提供2级检测器冷却功能，以实现最高的灵敏度和性能！非常适合长时间曝光，曝光最多可达8分钟。

可互换的狭缝（Interchangeable Slits Upgrades），可用于高分辨率HR光学平台，以提供更多的应用灵活性。

可以使用最小的狭缝来测量高散射样品，以获得极高的分辨率，也可以通过较大的狭缝来测量弱拉曼，以增加光通量。

Stellar CASE-Raman-785是一款便携式，坚固耐用的拉曼光谱系统，适用于“开放与测量”应用。

这个完整的系统包括高性能拉曼光谱仪（Raman-HR-TEC-785），大功率激光器和样品瓶架。

通常建议将Raman-SR-785系列光谱仪用于OEM和便携式应用，在这些应用中已知特定样品组并且在不使用检测器冷却的情况下也能很好地工作。

小区地库监控技术参数 (1)

监控网络部分：网络主干全部采用光纤作为传输设备，可以避免电磁及杂波干扰。

分线采用国标千兆网线-CAT6也就是六类网线（千兆网线的传输频率为1MHz～250MHz，千兆网线系统在200MHz时综合衰减串扰比（PS-ACR）应该有较大的余量，它提供2倍于超五类的带宽千兆网线的传输性能远远高于超五类标准，最适用于传输速率高于1Gbps的应用。

六类与超五类的一个重要的不同点在于：改善了在串扰以及回波损耗方面的性能，对于新一代全双工的高速网络应用而言，优良的回波损耗性能是极重要的。

This is information on a product in full production.May 2012Doc ID 2149 Rev 211/24L79xxCNegative voltage regulatorsDatasheet − production dataFeatures■Output current up to 1.5 A■Output voltages of - 5; - 8; - 12; - 15 V ■Thermal overload protection ■Short circuit protection■Output transition SOA protectionDescriptionThe L79xxC series of three-terminal negative regulators is available in TO-220, TO-220FP and D²P AK packages and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation; furthermore, having the same voltage option as the L78xx positive standard series, they are particularly suited for split power supplies. If adequate heat sinking is provided, they can deliver over 1.5 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with externalcomponents to obtain adjustable voltages and currents.Table 1.Device summaryPart numbersOrder codesOutput voltages TO-220D²PAK TO-220FP L7905C L7905CV L7905CV-DG (1)L7905CD2T -TRL7905CP- 5 V L7908C L7908CV L7908CV-DG (1)- 8 VL7912C L7912CV L7912CV-DG (1)L7912CD2T -TR L7912CP - 12 V L7915CL7915CVL7915CV-DG (1)L7915CD2T -TRL7915CP- 15 V1.TO-220 Dual Gauge frame.Contents L79xxC Contents1Diagram . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 2Pin configuration . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 3Maximum ratings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5 4Test circuit . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 5Electrical characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 6Application information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11 7Package mechanical data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13 8Revision history . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 232/24Doc ID 2149 Rev 21L79xxC Diagram 1 DiagramDoc ID 2149 Rev 213/24Pin configuration L79xxC 2 Pin configuration4/24Doc ID 2149 Rev 21L79xxC Maximum ratingsDoc ID 2149 Rev 215/243 Maximum ratingsNote:Absolute maximum ratings are those values beyond which damage to the device may occur.Functional operation under these condition is not implied.Table 2.Absolute maximum ratingsSymbol ParameterValue Unit V I DC input voltage for V O = - 5 to - 18 V -35Vfor V O = - 20 to - 24 V-40I O Output current Internally limited P D Power dissipationInternally limited T STG Storage temperature range-65 to 150°C T OPOperating junction temperature range0 to 150°C Table 3.Thermal dataSymbol ParameterD²PAK TO-220TO-220FPUnit R thJC Thermal resistance junction-case 355°C/W R thJAThermal resistance junction-ambient62.55060°C/WTest circuit L79xxC6/24Doc ID 2149 Rev 214 Test circuit5 ElectricalcharacteristicsRefer to the test circuits, T J = 0 to 125 °C, V I = -10 V, I O = 500 mA, C I = 2.2 µF, C O = 1 µFunless otherwise specified.Table 4.Electrical characteristics of L7905CSymbol Parameter Test conditions Min.Typ.Max.Unit V O Output voltage T J = 25°C-4.8-5-5.2VV O Output voltage I O = -5 mA to -1 A, P O≤ 15 WV I = -8 to -20 V-4.75-5-5.25VΔV O(1)Line regulation V I = -7 to -25 V, T J = 25°C100mV V I = -8 to -12 V, T J = 25°C50ΔV O(1)Load regulation I O = 5 mA to 1.5 A, T J = 25°C100mV I O = 250 to 750 mA, T J = 25°C50I d Quiescent current T J = 25°C3mAΔI d Quiescent current change I O = 5 mA to 1 A0.5mA V I = -8 to -25 V 1.3ΔV O/ΔT Output voltage drift I O = 5 mA-0.4mV/°C eN Output noise voltage B = 10Hz to 100kHz, T J = 25°C100µV SVR Supply voltage rejectionΔV I = 10 V, f = 120Hz5460dB V d Dropout voltage I O = 1 A, T J = 25°C, ΔV O = 100 mV 1.4VI sc Short circuit current 2.1A1.Load and line regulation are specified at constant junction temperature.

长焦广角数码相机推荐朗泰通相机电池怎么样

长焦广角数码相机推荐朗泰通相机电池怎么样机型特色：50倍光学变焦、智能防抖佳能PowerShotS某长焦系列数码相机一直都走在同类机型的最前端，佳能PowerShotS某50HS使S某系列产品在远望拍摄能力得到全面的提升，是一款旗舰级长焦数码相机，拥有了史上最高倍数的50倍光学变焦成为其最大的亮点。

相比之前竞争对手尼康P510的42倍变焦又提升到另一个高度。

S某50HS并没有提高像素，依然是采用1/2.3英寸、1210万像素的CMOS图像感应器。

依然采用佳能近年力推的HS系统，可有效提高弱光环境的拍摄能力。

同时搭载了今年全面更新的DICIG5影像处理器，让这款长焦机的连拍能力提升到全像素下高达每秒13张的速度。

作为一台旗舰级的长焦机，S某50更配备了等效24-1200毫米的50倍的光学变焦镜头，成为目前市面上倍数最大的长焦相机。

外观和上一代S某40HS相比又回到了佳能传统的长焦相机路线，类似今年佳能流线型的单反相机。

佳能S某50HS的体积为122.5某87.3某105.5毫米，比起单反相机要小得多，含电池595克的重量还算轻巧。

机身采用工程塑料作为材质，造工还算十分扎实。

佳能PowerShotS某50HS的外观和上一代机型变化比较大，从原来的弧形设计回归到传统的“类单反”造型，整体机身采用了工程塑料材质，质感还算不错。

手柄比较宽大，双手握持会更好。

50倍光学变焦是S某500HS的最大亮点，等效焦距为24-1200毫米，成为目前市面上最大变焦的数码相机。

拥有24毫米广角的佳能S某50HS广角也十分出色，24毫米十分好用，畸变控制得十分不错。

微距拍摄封面，佳能S某50HS同样具备0厘米的超强对焦。

不过远望能力越强悍，防抖性能显得更加重要，而S某50HS使用了佳能集合6种防抖模式于一身的智能IS光学防抖功能，最高能补偿4.5档的快门速度，即使在长焦端1200毫米下拍摄一样能拍摄出稳定清晰的照片。

机型特色：50倍变焦、全天候防护设计、五轴防抖在无反相机横行和大传感器卡片相机横空出世的2022年，富士在传统的卡片相机领域仅仅推出了一款旗舰级的复古卡片相机某100，对于大众而言几乎是没有选择可言。
