400A DC Solid State Relay special for frequency converters

GZ***DBP series solid state relay is a kind of semicondcutor switch specially designed for voltage type frequency converters and consists of photocoupling circuit and SCR circuit. Compared with other conventional contactors, it features low power consumption, fast speed, no spark interference, small size, light weight, long service life etc and really ideal replacement of ac magnetic contactors. It’s recommended to use with radiator together and paste the heat conducting silica gel between radiator and SSR.


- Bar type, convenient installation and operation

- High blocking voltage, 600~2200V selectable

- High power, high surge current capability

- LED input indication
