500-1000A solid state relays ssrPDF

Single phase Solid State Relay (SCR output)

Series GDH are power line relays allowing 500 to 1000 Amps. switching power,with Voltage ratings from 280 to 480 Volts A.C. GDH series is Dual SCR Power Hybrid technology provides highly efficient thermal management for greatly increased cyclic life.

High performance/low cost circuit design.
Logic compatible current regulated input.
2500 Vrms optical isolation.
Both “Zero Voltage” & phase controllable “Random Switching” versions.
High voltage (1200 Vpk) versions for 480 Vrms service.

LED-indication for control input.

Control voltage range:4~16 Vdc ,4 to 32 Vdc or 90~280Vac.
