Solid State Relays (triacs output single phase)
GD 10 to 40 Amps AC SSR
GD Series 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 10 to 40 Amps.
·Rated operational voltage 240V or 440 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.
