Potentiometer adjust control, with temporary stop function, 32-bit CPU, phase loss protection, undercurrent protection, overcurrent protection, and working status indication, 1000A trigger capacity.
STA83 potentiometer control electromagnetic control board is with ten-pulse trigger control, potentiometer to realizes magnetic output, with rated 220V excitation function, two buttons to achieve on, off and temporary release function. There is voltage limit setting and temporary release voltage point setting. 32-bit industrial grade microprocessor, highly digital safety standard design, use for electromagnet control applications. The fault alarm and interface parameters are displayed by LED digital tube menu, and the setting parameters will be automatically stored. The control board has the functions such as phase loss protection, undercurrent protection, overcurrent protection, and working status indication. The control process adopts three phase full control bridge rectification excitation and single phase full control bridge rectification demagnetization to achieve electromagnet control, which can trigger thyristor below 1000A and control board has conformal coating protection.
