SCR cut-off switch
First, the product overview
Rapid fluctuations in the grid load continues to increase, the traditional contactor, composite switching capacitor bank, has been unable to meet the demand for reactive power compensation. Dynamic switching using switching power supply electronic device response speed of less than 20ms, to meet the rapidly fluctuating load reactive power compensation requirements, the main applications and spot welding, rolling and other rapid fluctuations in load.
Second, the model description
Third, the performance characteristics
n products using high-power anti-parallel thyristor modules, optical isolation circuit, trigger circuit, protection circuit and cooling device
