Relays / Phase Monitoring Relays
STEP 1: Choose a correct control Mode
AA- AC Control AC
DA- DC Control AC
DD- DC Control DC
VA-Control and Adjust
LA- 4-20mA/0-10V Input
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.
