FAQ

Q:What is a DC Solid State Relay?

A DC Solid State Relay (DC SSR) is an electronic switch used to control DC circuits. It operates through semiconductor devices like MOSFETs or IGBTs, without mechanical parts, resulting in long lifespan, fast response, noiseless operation, and high reliability. Solid state relays are suitable for applications requiring rapid and frequent switching, such as automation control systems, industrial equipment, and heating control, enhancing system efficiency and reducing maintenance costs.

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.
