* 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: What is a solid state relay?
A solid state relay is a non-contact switch composed of microelectronic circuits, discrete electronic devices, and electronic power devices. It is a non-contact switching device with the characteristics of relays, in which semiconductor devices are used to replace traditional electrical contacts as switching devices. Single-phase SSR is a four-terminal active device, two of which are input terminals and the others are output terminals. Optical 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. It has the function of not only amplifying driving effect, but also isolation and is suitable for driving high-power switch-type actuators. Compared with the electromagnetic relay, it has higher reliability, no contact, long life, fast speed and small disturbance to the outside world and has been widely used.
