Solid State Relays

Solid state relays, as known as SSRs, are typically used to control large current loads with a small input control signal. Solid state relay is a kind of contactless switch composed of microelectronic circuit, discrete electronic device and electronic power device, which realizes the isolation between control end and load end.

ATO manufactures single phase and 3 phase solid state relays with wholesale price, including DC-AC and AC-AC, with load currents from 10A to 120A. In addition, compact industrial solid-state relay ATO supplied provides DC control AC with load current ranges of 60 amp, 80 amp, and 350 amp. They have been widely used with the advantages of high reliability, no contact, long life, fast speed, small anti-interference and so on.
