3 Phase 10A 25A 40A DA 60A 80A 100A 150 200A Three SSR 3 32V DC Control 24 480V AC Solid State Relay DC AC 40DA

relay STEP 1: Choose a correct control Mode AA AC Control AC DA DC Control AC DD DC Control DC VA Control and Adjust 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:20%,Capacitive load:10%. 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. PS: Our Heat Sink include 2 screws for install heat sink and a pack of thermal compound is applied to the bottom of the SSR 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.
