    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, fan forced cooling or water cooling is needed.
    * Heat sink is Not included.

    Tips: Single-phase solid state relay and three-phase solid state relay

    Single-phase solid state relay is a four-terminal active device, two of which are input terminals and the others are output terminals. Photo isolation lies between them. Once the input terminal is given DC or pulse signals to a certain current value, the output terminal can be changed from off-state to on-state.

    The three-phase AC solid state relay integrates three single-phase AC solid state relays, and directly switches over three-phase load such as AC electrical machine, heater, etc. through a single input to achieve convenient control. The insulation voltage between each phase, input and output, solid state relay and baseplate is greater than 2 000 V AC. The other basic indicators are the same as corresponding single-phase solid state relay. It should be pointed out that in some cases such as laboratory teaching where actual load current is not large, three-phase SSR is more convenient to use. But large current leads to more heating. At this moment, three single-phase solid state relays may be more reliable.
