FAQ

Q:How to confirm the current and voltage of the solid state relay against inductive load and resistive load?

A margin should be left when selecting the voltage and current of the solid state relay. For resistive load: the current is selected according to 2.5~4 times the load current, and the voltage is selected according to 2~2.5 times the load power. Inductive load: current is selected according to 3-7 times load current, voltage is selected according to 2.5-3 times load voltage.
