Relays / Phase Monitoring Relays
Single phase Solid State Relay
STEP 1: Choose a correct control Mode
AA- AC Control AC
DA- DC Control AC
DD- DC Control AC
STEP 2: Choose a correct type
Calculate ssr current :
Load constant current / coefficient = Rated SSR current
Rated SSR current x coefficient = Load contant current
Coefficient of Load type:
Resistive load : 0.5
Inductive load : 0.15
Capacitive load : 0.1
Example : A resistive load constant current is 10A,
the SSR current should pick : 10/0.5= 20A , select 25A rated model
STEP 3: Choose a suitable heat sink.
