Solid State Relay (500 to 1000A)
GDH 500 to 1000 Amps AC SSR
Series GDH are power line relays allowing 500 to 1000 Amps. switching power, with Voltage ratings 440 Volts A.C. GDH series is Dual SCR Power Hybrid technology provides highly efficient thermal management for greatly increased cyclic life.
- High power and high current. - High performance/low cost circuit design. - Logic compatible current regulated input. - 4000 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 to 16 Vdc,3 to 32 Vdc or 90 to 250Vac. - Industy standard “SCR Modules” package.
