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)
