SSR Solid State Relay are DC relay, Triac output. The triac version of the zero switching relay is a cheap solution for resistive loads the zero switching relay switch when the DC sine voltage just crosses zero. The switch turn off when the current crosses zero.
Control current: DC5-25mA
On Voltage:
Off Leakage current:
On-off time:
Dielectric strength: 2000VAC
Insulation Resistance: 500MOhm/500VDC
