    * 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: Solid state relay's working principle

    SSR can be divided into AC SSR and DC SSR according to application, which can act as the load switch in the AC or DC power supply respectively, and therefore, cannot be mixed. The AC SSR is taken as an example to illustrate the working principle solid state relay. As a whole, SSR has only two inputs (A and B) and two outputs (C and D), which is a four-terminal device.
    In its operation, as long as the A, B are given a certain control signal, you can control on-off state between C and D to achieve the switch function, in which the function of the coupling circuit is to provide an input/output channel for control signals input from A and B, but electrically disconnect input and output of SSRs to prevent the output from affecting the input. Components used in the coupling circuits are optical couplers, which has good action sensitivity, high response speed, high level of input/output insulation (withstand voltage). The load at the input is a light-emitting diode, which makes the SSR input very easy to match input signal level. In the usage, it can be directly connected with the computer output interface, that is, it is controlled by the logic level of "1" and "0".

    Works well just like the old one I replaced.
    Purchase this 80A solid state relay to change my old one. Works well just like the old one I replaced. The size is very suitable, not too small or too big and it’s easy to install. Exactly what I needed. Nice product.
