Notes on product selection:

According to the size of the load power, different current margin should be selected. The larger the power, the larger the current margin. Generally choose the current capacity of solid state relay is 3-6 times of the load current. In addition, add overcurrent protection to the load circuit to prevent short circuits. The method is: the load circuit is connected in series with a fast circuit breaker or fast fuse.

In the output circuit, overvoltage protection measures should be added. Method: output parallel connected varistor (MOV), or add RC resistive capacitive absorption circuit. MOV: 440V power supply select 470V ~ 680V, 660V gear select 1100 ~ 1200V. Or with the factory's AC overvoltage protection absorber. Overcurrent protection method: Connect a quick disconnect switch or quick fuse in series with the load circuit.

If the load power supply is taken from the AC power supply through rectification into DC pulsating power supply, the filter capacitor must be added at the power end for filtering. The size of the capacitance is determined by the size of the load current.

According to the size of the selected solid state relay current, working mode, environmental conditions, the choice of heat sink should be different, the area of the heat sink should be large rather than small.

When installing, it is required that the contact surface between the heat sink and the product shall be flat and smooth, and a layer of thermally conductive silicone grease shall be applied to its surface, and finally the screws set with flat washers and spring washers shall be tightened and fixed symmetrically.

The control terminal is equipped with interlock and time delay functions, so there is no need to attach relevant protective measures when using.
