Product details

Three phase Solid State Voltage Regulator

Feature:

♦Integrates synchronous signal, shaping circuit, amplifying circuit, phase-shift trigger and output thyristor in one.
♦The weak current part and the strong current part are optically isolated.
♦Easy to install, no additional synchronous transformer and external neutral wire are needed.
♦Small size, wide voltage adjustment range, stable and reliable operation.
♦Mainly used in industrial electric furnaces, electric heating ovens, lighting and other equipment for voltage regulation, temperature regulation, light regulation, etc.
