产品详情介绍
87TS50R1214 GKWE驱动控制卡
额定625…1250 A的控制器额定电流为625…1250 A的控制器需要共同控制才能正常工作活动控制电源通过接线板连接到产品CP1，位于端子1和4。该单一连接点为控制器供电模块、接触器和风扇。控制电源必须为110/120V AC或230/240V AC，仅50/60 Hz。至少800 VA的控制电源必修的。控制电源要求包括控制模块（75 VA），旁路接触器（最大526 VA）和风扇功率（150 VA）。
根据具体应用，附加控制电路变压器可能需要VA容量。
控制额定功率为230/240V AC的装置有一个欠压继电器安装。2014年之前建造的机组可能在欠压继电器。如果有电位计，则必须对其进行设置根据图36，2014年以后建造的机组可能不会电位计，因为设置在内部编程到欠压继电器，无需调整。本节涵盖了您需要解决的一些注意事项，具体取决于在您的应用程序上。
保护模块您应该安装一个包含MOV（金属）的保护模块（见图65氧化物变阻器），以保护SMC Flex电源组件免受电气影响瞬态和/或电气噪声。您可以安装额定电压为200…600V的保护模块控制器来保护来自电气瞬变的功率元件。
保护模块卡夹线路上产生的电压瞬变
以防止此类浪涌损坏SCR。强烈建议使用MOV，因为480V和600V MOV分别提供1400V和1600V的最大保护。可能会出现两种情况，表明需要用于使用保护模块。1.瞬态峰值-瞬态峰值通常会出现在线路上为SMC Flex控制器馈电或从SMC Flex馈电负载控制器。当设备带有开路的载流电感。当触点断开电路。这些示例包括轻载电机、变压器、螺线管、全电压起动器和机电制动器。闪电也会导致尖峰。
2.快速上升的Wavefronts-如果SMC Flex控制器安装在存在快速上升波前的系统，尽管不是可能需要高峰值电压、保护模块。闪电也会导致这种类型的响应。此外，如果控制器与其他SCR设备（如AC/DC）在同一总线上驱动器、感应加热设备或焊接设备）、点火这些设备中的SCR可能会产生噪音
Controllers rated 625…1250 A
Controllers that are rated 625…1250 A require common control for proper operation. Control power is connected to the product through terminal block CP1, at terminals 1 and 4. This single connection point feeds the control module, contactors, and fans. Control power must be supplied as 110/120V AC or 230/240V AC, 50/60 Hz only. A control power source of at least 800 VA is required. The control power requirements include the control module (75 VA), bypass contactors (526 VA max), and fan power (150 VA). Depending on the specific application, additional control circuit transformer VA capacity may be required. Units with a control power rating of 230/240V AC have an undervoltage relay installed. Units built prior to 2014 may have potentiometers on the undervoltage relay. If potentiometers are present, you must set them according to Figure 36. Units built later than 2014 may not have potentiometers, because the settings are programmed internally to the undervoltage relay and no adjustment is required.
This section covers some considerations
that you need to address, depending on your application. Protective Modules You should install a protective module (see Figure 65) containing MOVs (Metal Oxide Varistors) to protect the SMC Flex power components from electrical transients and/or electrical noise. You can install protective modules controllers rated from 200…600V to protect the power components from electrical transients. The protective modules clip voltage transients that are generated on the lines to prevent such surges from damaging the SCRs. The use of MOVs is highly recommended, because 480V and 600V MOVs offer maximum protection of 1400V and 1600V, respectively.
There are two general situations that may occur that could indicate the need for using the protective modules. 1. Transient Spikes — Transient spikes will typically occur on the lines feeding the SMC Flex controller or feeding the load from the SMC Flex controller. Transient spikes are created on the line when devices are attached with current- carrying inductances that are open-circuited. The energy stored in the magnetic field is released when the contacts open the circuit. Examples of these include lightly loaded motors, transformers, solenoids, full voltage starters, and electromechanical brakes. Lightning can also cause spikes. 2. Fast-rising Wavefronts — If the SMC Flex controller is installed on a system that has fast-rising wavefronts present, although not necessarily high peak voltages, protective modules may be needed. Lightning can also cause this type of response. Additionally, if the controller is on the same bus as other SCR devices (such as AC/DC drives, induction heating equipment, or welding equipment), the firing of the SCRs in those devices can cause noise.
