SSR 10DD 25DD 40DD 80A 100A SSR Single Phase DC Control 3 32VDC to 220VDC 600V 10A 25A 40A DD Solid State Relay 80DD

relay Attention:Solar equipment is a mixed load, we do not recommend using solid state relays.If you want to try, you need to buy a solid state relay with 10 times the current.At the same time, if the solid state relay does not work normally on the solar equipment, we do not provide return service. STEP 1: Choose a correct control Mode AA AC Control AC DA DC Control AC DD DC Control DC STEP 2: Choose a correct type Current of Equipment Ratio Current of SSR PS: 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 state, multimeter light red . According to the conventional detection methods of solid state relays: a load is required to test the switching state. Using an incandescent lamp as a dummy load is an obvious way to test continuity.
