埃斯顿 PXS24 电子保护模块应用指南说明书
PXS24Application NoteEaton - A new era of electronic protective devicesExample with activeActive current limitation of the PXS24The electronic protection module PXS24 switches, in contrast to conventional thermomagnetic circuit breakers, not mechanically but via a semiconductor element. This allows a more sensible response and guarantee a safe switch off in circuits with long lines and small wire cross sections. The PXS24 also has anactive current limiter, which protects the upstream power supply in case of an overload or short-circuit. This ensures selectivity, since only the concerned circuit is switched off and makes the troubleshooting more easy. Once the current reaches 1.3 times I N , PXS24 reduce the current to 1.25 times I N , limit it to that level and switch-off according to the switch-off time. This protects the feeding power supply. The guaranteed non-tripping value of the PXS24 is 1.1 times the rated current. In comparison, at a conven-tional circuit breaker, the occurring fault current can exceed the rated current up to 20 times, depending on the characteristics. This leads to a higher stress factor and in worst case to a break-down of the upstream power supply.Based on the defi ned switch-off times PXS24 is also able to hand-le system caused load peaks which normally leads to a nuisance tripping. Another signifi cant advantage is to guarantee a reliable operation of the power supply because the current limitation al-lows an easy dimension of the system. 100% of the load carrying capacity can be used without the risk to generate a unwanted shut down of the system.Today’s power supplies can have an integrated …Power Boost“, which allows that the rated current can be exceed by a certain factor. Thus, e.g. The Eaton PSG power supplies are capable of holding 150% of the rated power for 5s. In case of a short circuit or extreme overload, the current can quickly reach 10 times the rated current and, if not limited, the power supply switch off (2).If you have an electric overcurrent protection with active current limitation (PXS24), the current can increase to a maximum of 1.3 times the value of the rated current of the device in case of a short circuit and the power supply unit is protected (1).This also results in easier fault fi nding, since it is immediately apparent in which path there is a malfunction.Note for UL applications: The PXS solid state overcurrent protec-tor has been tested in accordance to UL 508 and CSA 22.2 No. 14 for DC general use. Temperature, overload and endurance, dielectric and breakdown of component tests were conducted. Calibration and overloaded operation tests were conducted in accordance with UL 2367.Time / Current table Current I N Shutdown Active current limitation 2A 470 ms 1.25 x I N 4A 280 ms 1.25 x I N 6A 170 ms 1.25 x I N 8A 110 ms 1.25 x I N 10A 90 ms 1.25 x I N 13A 80 ms 1.25 x I N 16A70 ms1.25 x I NExample without active(1) (2)Here you can see the much more sensitive trip range of the electronic protection unit (e2 - e16) compared to the conventio-nal, thermomagnetic CB (FAZ B2 - B16 or FAZ Z2 - Z20). Those switching devices whose trip ranges are within the trip limits of the power supply (green shaded area) also ensure that in case of a short circuit or an extreme overload the power supply does not switch off.Overload behaviorCompared to short-circuit tripping, the conventional circuit brea-ker reacts much more slower in the event of a thermal overload, as a result of which the upstream power supply can also be overstressed. On the other hand, the PXS24 does not differen-tiate between short circuit and overload and thus offers a more precise shutdown behavior.The PXS24 processes the overload just like a short circuit. Once the current reaches 1.3 times I N , PXS24 reduce the current to 1.25 times I N , limit it to that level and switch-off according to the switch-off time:The following values apply to thermal overload:Conventional CB (FAZ)IEC/EN 60947-2IEC/EN 60898-1Fixed non-tripping current 1.05*I N > 1h 1.13*I N > 1h Fixed tripping current1.30*I N < 1h1.45*I N < 1hComparison of the DC short-circuit release with:- Conventional thermomagnetic circuit breakers (FAZ)- Electronic protection module without active current limitation- Electronic protection module with active current limitation (PXS24)Time / Current table Current I N Shutdown Active current limitation 2A 470 ms 1.25 x I N 4A 280 ms 1.25 x I N 6A 170 ms 1.25 x I N 8A 110 ms 1.25 x I N 10A 90 ms 1.25 x I N 13A 80 ms 1.25 x I N 16A70 ms1.25 x I N20 A Power SupplyEaton PSGPowerboost max. 5sWhen using an electronic protection module without current limiter, a short circuit or extreme overload will cause a sudden shutdown of the power supply unit.The maximum upper limit of the current to be reached in the event of a short circuit in the PXS24 is 1.3 x I for all rated currents (2 - 16 A). All values are within the control limits of the power supply and 100% selectivity can be used.Tripping areas of the FAZ circuit breakers with Z-characteristic (2,8 - 4,2 x I ) in the event of a short circuit (magnetic release).Tripping areas of the FAZ circuit breakers with B-characteristic (4.2 - 7,1 x I ) in the event of a short circuit (magnetic release).Current I [A]V o l t a g e U = 24 V D C9010238083516Follow us on social media to get the latest product and support information.Eaton is a registered trademark.All other trademarks are property Eaton Industries (Austria) GmbH Scheydgasse 421210 Vienna AustriaEatonEMEA Headquarters Route de la Longeraie 71110 Morges, Switzerland Eaton.eu© 2018 EatonAll Rights Reserved Printed in AustriaPublication No. BR019012EN Article number 195234-MK December 2018Changes to the products, to the information contained in thisdocument, and to prices are reserved; so are errors and omissions.Only order confirmations and technical documentation by Eaton is binding.

SABINE FBX-2420反馈抑制器
FBX-2420反馈抑制器FBX的功能采用SMART Filter技术的FBX功力在于是在节目演出期间，而不是在系统调整期间控制反馈的能力。
如果在极重要的表演瞬间，大型独凑演出中间或刚好在尊敬领导开始演讲时发生反馈，要把一个抑制反馈的滤波器无声地调节到反馈频率上是很困难的。
幸亏FBX作为一种非常先进的自动参数调整装置，它的测试装置和滤波器可以自动寻找反馈频率、精确地调整滤波器的位置、建立一种带宽极窄、吸收深度足够滤波器，从而自动地消除烦恼的啸叫声。
FBX全部是自动调整的，它的调整速度比任何其他方法更快。
如何进行？首先要考虑的是反馈控制滤波器的品质。
滤波器的品质可以用它的调整速度、精度、分辨率和声音的一致性来衡量。
速度：在全新的FBX 2400中运行的SMART Filter算法的数字信号处理器的速度优势明显超过所有其他的自动反馈控制器，提高了系统调整的速度，可在不到30秒的时间内完成FBX 的各种参数的自动调整。
演出期间，24bit的FBX会连续监视反馈，决不允许它破坏表演。
滤波器几乎可被立即设置（1KHz频率在0.4秒之内）。
消除反馈的速度可用反馈信号振幅的衰减时间来说明。
上面的图说明竞争者的消除反馈速度，注意，图中消除反馈的反应时间更长。
下图说明FBX更快的消除反馈时间。
精度：是音乐信号还是反馈信号呢？这是反馈控制器最难回答的问题。
错误的判断意味着浪费滤波器（减少系统增益）和产生不必要的“孔汩”声。
FBX杰出的性能总是能精确地判断。
新的SMART Filter技术使它更为出色。
不复杂的反馈控制器把滤波器置于一些大声音的位置上，即使是音乐节目也是如此。
但是，FBX使用的专利技术可以分析节目的谐波分量，因为谐波分量上的反馈是低的，而音乐和语言节目都包含丰富的谐波分量，因此FBX可以正确的回答是音乐还是反馈问题。
分辨率：这是一个大问题，现在我们知道反馈是一种偶然事件，我们需要精确地瞄准它。
很多反馈控制器把滤波器一般调到反馈频率的附近，然后依靠增加滤波器的带宽，直至消除反馈。

All applicable legal or institutional installation regulations must be complied with during installation.The switch for changing the direction of motion and so the closing point may be adjusted only by authorised specialists. The direction of motion is critical, particularly in connection with frost protection circuits.The device may only be opened at the manufacturer's site. It does not contain any parts that can be replaced or repaired by the user.The device contains electrical and electronic components and must not be disposed of as household refuse. All locally valid regulations and requirements must be observed.NV24A-MP-REProduct featuresOperating mode Conventional operation:The actuator is connected with a standard control signal of 0...10 V and drives to the positiondefined by the control signal. The measuring voltage U serves for the electrical display of theactuator position 0.5...100% and as control signal for other actuators.Operation on Bus:The actuator receives its digital control signal from the higher level controller via the MP-Busand drives to the position defined. Connection U serves as communication interface and doesnot supply an analogue measuring voltage.Converter for sensors Connection option for a sensor (passive or active sensor or switching contact). The MPactuator serves as an analogue/digital converter for the transmission of the sensor signal viaMP-Bus to the higher level system.Parametrisable actuators The factory settings cover the most common applications. Single parameters can be modifiedwith the Belimo service tools MFT-P or ZTH EU.Mounting on third-party valves The RetroFIT+ actuators for installation on a wide range of valves from various manufacturersare comprised of an actuator, bracket, universal valve neck adapter and universal valve stemadapter. Adapt the valve neck and valve stem to begin with, then attach the RetroFIT+ bracketto the valve neck adapter. Now fit the RetroFIT+ actuator into the bracket and connect it to thevalve. Whilst taking the position of the valve closing point into account, secure the actuator tothe bracket and then conduct the commissioning process. The valve neck adapter/actuatorcan be rotated by 360° on the valve neck, provided the size of the installed valve permits.Mounting on Belimo valves Use standard actuators from Belimo for mounting on Belimo globe valves. The installation ofRetroFIT+ actuators on Belimo globe valves is technically possible.Manual override Manual override with push-button possible (the gear train is disengaged for as long as thebutton is pressed or remains locked).The stroke can be adjusted by using a hexagon socket screw key (4 mm), which is insertedinto the top of the actuator. The stroke shaft extends when the key is rotated clockwise.High functional reliability The actuator is overload protected, requires no limit switches and automatically stops whenthe end stop is reached.Home position Factory setting: Actuator stem is retracted.The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuatorcarries out an adaptation, which is when the operating range and position feedback adjustthemselves to the mechanical setting range.The actuator then moves into the position defined by the control signal.Adaptation and synchronisation An adaptation can be triggered manually by pressing the "Adaptation" button or with the PC-Tool. Both mechanical end stops are detected during the adaptation (entire setting range).Automatic synchronisation after pressing the manual override button is configured. Thesynchronisation is in the home position (0%).The actuator then moves into the position defined by the control signal.A range of settings can be adapted using the PC-Tool (see MFT-P documentation)Setting direction of motion When actuated, the stroke direction switch changes the running direction in normaloperation.AccessoriesGateways Description TypeGateway MP to BACnet MS/TP UK24BACGateway MP to Modbus RTU UK24MODNV24A-MP-REElectrical accessoriesDescriptionType Auxiliary switch 2x SPDT add-onS2A-HMP-Bus power supply for MP actuatorsZN230-24MP Mechanical accessoriesDescriptionType Spacer ring for LDM, stroke 20 mm ZNV-203Spacer ring for Sauter, stroke 20 mm ZNV-204Adapter kit DanfossZNV-205ToolsDescriptionType Service tool, with ZIP-USB function, for parametrisable andcommunicative Belimo actuators, VAV controller and HVAC performance devicesZTH EUBelimo PC-Tool, Software for adjustments and diagnostics MFT-P Adapter for Service-Tool ZTHMFT-C Connecting cable 5 m, A: RJ11 6/4 ZTH EU, B: 6-pin for connection to service socketZK1-GEN Connecting cable 5 m, A: RJ11 6/4 ZTH EU, B: free wire end for connection to MP/PP terminalZK2-GENAccessoriesElectrical installationSupply from isolating transformer.Parallel connection of other actuators possible.

If required, custom versions of the actuator can be ordered. The parameters are variable and can be changed by three means: Factory pre-set or custom configuration, set by the customer using PC-Tool software or the handheld ZTH US.For fail-safe, modulating control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications. A feedback signal is provided for position indication for primary and secondary applications. Two AF's can be piggybacked for torque loads to max. 360 in-lb. Minimum 3/4" diameter shaft. OR Maximum of three AF's can be piggybacked for torque loads to max. 432 in-lb. Minimum 3/4" diameter shaft. Primary and secondary wiring for either configuration. Actuators must be mechanically linked.When not mechanically linked, actuators must be wired in parallel.The AF..24-MFT N4 actuator provides 95° of rotation and is provided with a graduated position indicator showing 0° to 95°. The actuator will synchronize the 0° mechanical stop or the physical damper or valve mechanical stop and use this point for its zero position during normal control operations. A unique manual override allows the setting of any actuator position within its 95° of rotation with no power applied. This mechanism can be released physically by the use of a crank supplied with the actuator. When power is applied the manual override is released and the actuator drives toward the fail-safe position. The actuator uses a brushless DC motor which is controlled by an Application Specific Integrated Circuit (ASIC) and a microprocessor. The microprocessor provides the intelligence to the ASIC to provide a constant rotation rate and to know the actuators's exact position. The ASIC monitors and controls the brushless DC motor's rotation and provides a Digital Rotation Sensing (DRS) function to prevent damage to the actuator in a stall condition. The position feedback signal is generated without the need for mechanical feedback potentiometers using DRS. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. The AF..24-MFT N4 is mounted directly to control shafts up to 1.05" diameter by means of its universal clamp and anti-rotation bracket. The spring return system provides minimum specified torque to the application during a power interruption. The AF..24-MFT N4 actuator is shipped at 5° (5° from full fail-safe) to provide automatic compression against damper gaskets for tight shut-off.Installation Note: Use suitable flexible metallic conduit or its equivalent with the conduit fitting. Not suitable for plenum applications.For low ambient temperatures, the optional supplemental (-Y) Heater add-on is available.Typical specification Factory settings Spring return control damper actuators shall be direct coupled type which require no crank armand linkage and be capable of direct mounting to a jackshaft up to a 1.05” diameter. Theactuator must provide modulating damper control in response to a 2 to 10 VDC or, with the addition of a 500Ω resistor, a 4 to 20 mA control input from an electronic controller orpositioner. The actuators must be designed so that they may be used for either clockwise orcounter clockwise fail-safe operation. Actuators shall use a brushless DC motor controlled by a microprocessor and be protected from overload at all angles of rotation. Run time shall be constant, and independent of torque. A 2 to 10 VDC feedback signal shall be provided for position feedback or primary and secondary applications. Actuators with auxiliary switches must be constructed to meet the requirements for Double Insulation so an electrical ground is not required to meet agency listings. Actuators shall be cULus listed and have a 5 year warranty, and be manufactured under ISO 9001 International Quality Control Standards. Actuators shall be as manufactured by Belimo.Default parameters for 2 to 10 VDC applications of the AF..-MFT actuator are assigned during manufacturing. If required, custom versions of the actuator can be ordered. The parameters are variable and can be changed by three means: Factory pre-set or custom configuration, set by the customer using PC-Tool software or the handheld ZTH US.AccessoriesElectrical accessories Description TypeGasketfor cable gland(NEMA 4 models)11097-00001Cable Gland (NEMA 4 models)43442-00001DC Voltage Input Rescaling Module IRM-100Auxiliary switch, mercury-free P475Auxiliary switch, mercury-free P475-1Convert Pulse Width Modulated Signal to a 2...10 V Signal for BelimoProportional ActuatorsPTA-250Positioner for wall mounting SGA24Positioner for front-panel mounting SGF24Gateway MP to BACnet MS/TP UK24BACResistor, 500 Ω, 1/4" wire resistor with 6" pigtail wires ZG-R01Resistor kit, 50% voltage divider ZG-R02Transformer, AC 120 V to AC 24 V, 40 VA ZG-X40 Mechanical accessories Description TypeAnti-rotation bracket, for AF / NF AF-PBall joint suitable for damper crank arm KH8 / KH10, Multipack 10 pcs.KG10ADamper crank arm Slot width 8.2 mm, clamping range ø14...25 mm KH10Push rod for KG10A ball joint 36” L, 3/8” diameter SH10Wrench 0.32 in and 0.39 in [8 mm and 10 mm]TOOL-06Wrench 0.512 in.
