Widely Application
Solid state relays can be widely used to control computer peripheral devices, thermostats and resistance furnaces, AC motors, intermediate relays and solenoid valves, copiers and fully automatic washing machines, signal lights, traffic lights and scintillators, lighting and stage lighting, CNC remote control systems, automatic fire protection and security systems, high-power thyristor triggering and industrial automation equipment, etc.
Advantage
It is specially designed for harsh environments with corrosion, humidity or light-proof/explosion-proof requirements and frequent turn-on/off requirements.

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.
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.

STEP 1: 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 2: 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) and a pack of thermal compound (is applied to the bottom of the SSR)
