The control board is equipped with functions such as automatic phase identification, phase loss protection, motor soft start, soft stop, constant current output, constant speed output, overvoltage protection, overcurrent protection, and working status indication. It has a three-phase full-controlled bridge rectifier trigger mode, which can trigger SCRs below 5000A, and is widely used in high-power and high-torque DC motor speed control systems.

This trigger board uses industrial-grade high-performance microprocessors, and continues to lead the innovation of core control algorithms and software technologies in the industry. The structure of the control software package and the processing speed of the single-chip microcomputer can ensure that the adjustment effect of all control loops is controlled by the twelve main circuits. The conversion time of the silicon bridge is completed to ensure that the sampling time of the speed loop (current loop) is less than 3.33mS (50HZ power supply) or 2.77mS (60HZ power supply) to obtain superior performance.

The DC motor speed control board has a variety of given control signal options, supports 0-5Vdc, 0-10Vdc and other analog input automatic control modes, and can also be controlled manually by potentiometer (10K 2W) and through the panel buttons, which is flexible and convenient. The parameters are all digital, and there is no temperature drift change, which improves the adjustment accuracy and power utilization efficiency, reduces the pollution of the power supply, has high voltage regulation accuracy, and has good reliability and stability. At the same time, the control board has strong anti-interference ability, adopts unique anti-interference measures, runs normally in harsh interference environment, and uses isolation technology for all outputs, has multiple protection functions, and has a wide range of applications.
