CG ZGT-40DA 10A 25A 40A Single Phase DC To AC SSR Heat Sink 24-480VAC Relay Input 3-32VDC With Plastic Cover Solid State 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)

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.
