Product Details
Single phase Solid State Relay (SCR output)

Series GDH are power line relays allowing 200 to 400 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.

Features
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.
