Single Phase Solid State Relay Resistance Voltage Regulator

VR to AC/Input 470~560Kohm To Output 24~480VAC /Maximum Current 40A

SSR series solid state relays (screw terminal connection) are of high strength, impact resistance and strong vibration resistance, with low requirement for input current. They can be easily connected with digital control circuits of computers. . They are updated products of AC and DC contactors. They are specially designed for harsh environments with corrosion, humidity or light-proof/explosion-proof requirements and frequent turn-on/off requirements.

·The current on the product is the maximum load current, not the rated current.

·Think more than others

·Each package with 2 mini bag of thermal grease which apply on the back of the SSR to make the temperature dissipate faster.

·Steps are as follows:

·1.Wipe the back of the SSR clean to remove the dust.

·2.Squeeze some thermal grease on the SSR back.

·3.Use the brush to spread the thermal grease.

·4.Apply thermal grease evenly.

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.
