Single Phase SSR (SCR output 200 to 350A)
GDH 200 to 350 Amps AC SSR
Series GD Solid State Relays are AC relays,Triac Output. The triac version of the zero switching relay is an inexpensive solution for resistive loads. The zero switching relay switches on when the AC sine voltage just crosses zero,and switches off when the current crosses zero.
·Rated operational current 200A to 350Amps.
·Rated operational voltage 280V or 480 V
·Input Voltage Range 4 to 16 Vdc,3 to 32 Vdc or 90 to 250 Vac.
·4000 Vrms Optical Isolation.(input/output)
·Both "Zero Voltage" & phase controllable "Random Switching" versions.
·LED-indication for control input.
