    Note:

    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: Solid state relay's working principle

    SSR can be divided into AC SSR and DC SSR according to applications, 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.
