    1. When the load is a resistive load, the maximum load current of the selected SSR should be 2~3 times greater than the actual load current;
    2. When the load is an inductive load, the maximum load current of the selected SSR should be more than 7~8 times the actual load current.
    3. When the maximum load current is higher than 10A, a heat sink must be installed to the solid state relay, or the SSR relay should be mounted on a metal base plate with heat dissipation effect, and the thermal grease is applied between them.

    Tips: Applications of solid state relays

    Solid state relays have been widely used in computer's peripheral interface devices, electric furnace's heating thermostat system, CNC machine, remote control system, industrial automation devices; signal lights, scintillators, stage's lighting control system; instrumentation, medical equipment, copiers, automatic washing machines; automatic fire protection and security system as well as the switch of power capacitor compensated by power factors of the power grid, etc. In addition, they are widely used in the fields of chemical industry, coal mine and other occasions requiring explosion-proof, moisture-proof and anti-corrosion.

    Solid state relay (SSR) is simple but widely used in the automation fields. Thus, it is not complex to wire a solid state relay. In this vedio, ATO takes a 40 Amp SSR (DC - AC) for example to show the wiring of a SSR and then switch on/off a motor with this SSR.
