AS590 motor soft starter control board

The AS590 motor soft start trigger board is a simplified version of the 580 series. It adopts a 32-bit high-performance microprocessor and a highly digital military quality design. It is specially designed for three-phase AC motor soft start occasions with bypass output control. Function parameter setting adopts key operation, fault alarm, interface parameter adopts LCD liquid crystal screen Chinese display, setting parameter is automatically stored. The soft start mode is voltage ramp, voltage sudden jump and current limit soft start, so that the motor can achieve a smooth start under any working conditions, protect the drag system, reduce the impact of the starting current on the power grid, and ensure the smooth deceleration and soft stop of the motor , It effectively solves the parking surge problem of the inertial system, eliminates the feedback impact of the drag system, and can adjust various parameters in the starting process according to the characteristics of the motor load, such as overcurrent value, starting time, control panel belt Power-on soft start, soft stop, over-current protection, working status indication. With thyristor anti-parallel AC trigger mode, it can trigger SCR below 1000A, and it is suitable for various load types such as three-phase AC motor soft start in various fields of industry.

By controlling the starting voltage of the motor, excessive peak values of starting torque and starting current are avoided. On the one hand, the working machine can be protected from excessive acceleration torque stress during the start of the AC motor, and on the other hand, the power supply system can be prevented from being impacted by excessive starting current, which greatly reduces the mechanical stress on the conveyed object. , Reduce the wear of working machinery and transmission parts, so as to reduce maintenance, ensure work safety and extend the service life of equipment.

The soft-start thyristor trigger board has good reliability and stability, strong anti-interference ability, unique anti-interference measures, normal operation in harsh interference environments, complete self-diagnosis and motor operation protection functions of the soft-start board, power failure protection, silicon wear Protection, overload protection, phase sequence protection, phase failure protection, etc. Therefore, all kinds of interference and fault signals from external or internal production will make the performance of the soft start board safer and more reliable because of the above protection functions. All outputs adopt isolation technology, which has a wide range of applications and has complete fault and alarm detection and Protection function, all parameters are digital, no temperature drift changes, improve the regulation accuracy and power utilization efficiency.
