Can You Switch Dc with a Solid State Relay

Can a DC load be used with Solid-state Relays for AC loads? No, it cannot be used. The element characteristics of Solid-state Relays will not allow it to reset if a DC load is used.

Can a relay control DC?

They rely on the reverse-bias portion of the AC cycle to switch off. Other solid state relays use FETs as their switching component and those relays may work with DC. It all depends on what the specific relay is rated for, and the only way to know is to carefully read the relay’s data sheet. The answer is no!

Can solid state relays switch AC?

A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage (AC or DC) is applied across its control terminals. … The relay may be designed to switch either AC or DC loads.
