ST37 Three Phase Thyristor Power Voltage Regulator Module

ST37 thyristor voltage regulator module adopts split structure design, the main control part and the trigger part are separated from each other. It is suitable for high-power control occasions of one-to-multi-channel trigger pulse wave board, triggering pulse wave board is with  independent DC24 power supply, the main control board is a functional prototype of ST33. The specific functions can be referred to the ST33. Only the different trigger pulse board are required.

This model requires the customer to purchase in large quantity. If the quantity is small, please select ST33.

The control board can achieve the use of various functions such as thyristor rectifier, motor soft start, charge and discharge, etc., and the three-phase or single-phase, high-power or high-voltage, with strong flexibility. Different requirements can be customized according to customer's needs.

Various trigger pulse wave module: 1140V three-phase six-pulse moudle, 380V/660V three-phase six-pulse module, 220V/380V single-phase four-pulse module, 220V/380V single-phase two-pulse module.
