Description

SPECIFICATIONS

Brand Name: NONE

Certification: CE

Contact Load: Low Power

High-concerned chemical: none

Model Number: DD DA AA

Origin: Mainland China

Theory: Solid State Relay

Use: General Purpose

Voltage: 220V

Attention：Solar equipment is a mixed load, we do not recommend using solid state relays.If you want to try, you need to buy a solid state relay with 10 times the current.At the same time, if the solid state relay does not work normally on the solar equipment, we do not provide return service.

STEP 1: Choose a correct control Mode

AA- AC Control AC

DA- DC Control AC

DD- DC Control DC

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:30%

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.

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.
