SSR-10DD 25DD 40DD 80A 100A SSR Single Phase DC Control DC 3-32VDC to 220VDC 600V 10A 25A 40A DD Solid State Relay(Size:10ADD)

Solid State RelaysSTEP 1: Choose a correct control ModeAA- AC Control ACDA- DC Control ACDD- DC Control DCSTEP 2: Choose a correct typeCurrent of Equipment/Ratio = Current of SSRPS: The Ratio depend on the kind of your loading equipment.Resistive load :70%, Inductive load:30%STEP 3: Choose a suitable heat sink.During the useage of SSR, it will give out a lot of heat, so in order to extend the life of your SSR, please install a heat sink , also if the current is over 60A,the cooling fan also required.NOTICE:The inside of the solid-state relay is a semiconductor. A semiconductor switch is a non-physical contact switch. if use a multimeter diode or resistor to test ,it always show a high-impedance st
