    Note:
    * When the load current is higher than 10A, a heat sink must be added to the SSR or the SSR should be mounted on a metal base plate with heat dissipation effect, and apply the thermal grease between them. 
    When the load current is higher than is 40A or more, it also needs to add fan cooling or water cooling.
    * Heat sink is Not included.

    Tips: 4 tips for installation and use of solid state relays

    1. In the event of long-term operating current more than 5A, solid state relay must be equipped with a radiator matched, the temperature of whose baseplate shall not exceed 80 ℃ in operation. If the ambient temperature is too high, air cooling must be adopted to accelerate air flow for better heat dissipation.
    2. In order to ensure that the solid state relay contacts closely the surface of the radiator in the process of installation to achieve a better heat dissipation effect, please install the heat-conducting film in parallel between the SSR baseplate and contact surface of the radiator and tighten the fixing screw. Appropriate amount of thermal grease, if any, may be coated evenly on the solid state relay's baseplate and tighten the fixing screw.
    3. In order to prevent breakdown damage to SSRs caused by load short-circuit or over-current, voltage overload, it is recommended to install and use to a special fast acting fuse matched. For inductive load, it is also necessary to install varistors and RC absorption circuits at the solid-state output. For a DC SSR, a freewheeling diode and other protection devices shall be installed if inductive load exists.
    4. Solid state relays work must ensure sufficient operating voltage and current but no more than nominal trigger voltage and current values. For example, the control terminal 3-32V DC means that the minimum input voltage shall not be less than 3VDC, and the maximum shall not exceed 32V DC. Therefore, trigger requirements of SSRs should be met when solid state relays are used in series or parallel.

    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.
