DS520 DC motor speed control board

DS520 DC motor speed control trigger board is a highly digital military quality design, Fuzzy-PID parameter open adjustment, integrates open loop speed control, closed loop constant speed and constant current three adjustment methods, and controls the thyristor to achieve constant speed current limit Or constant current speed limit, function parameter setting adopts button operation, fault alarm, interface parameter adopts LED digital tube display, setting parameter is automatically stored. The control panel is equipped with functions such as automatic power frequency identification, power-on soft start, soft stop, constant current output, constant speed output, overvoltage protection, overcurrent protection, and working status indication. It has a single-phase full-control bridge rectifier trigger mode, which can trigger a thyristor below 3000A, and is widely used in high-power and high-torque single-phase DC motor speed control systems.

The DC motor speed control trigger board has a variety of given control signal options, supports 0-5Vdc, 0-10Vdc, 0-10mA and other analog input automatic control modes, and can also be controlled by potentiometer (10K 2W) and manual control through panel buttons , Flexible and convenient, all parameters are digital, no temperature drift changes, improve the adjustment accuracy and power utilization efficiency, reduce the pollution of the power supply, with high voltage stabilization accuracy, 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.
