Solid State Relays
A solid state relay (SSR) is a non-contact switch composed of microelectronic circuits, discrete electronic devices, electronic power devices, realizing the isolation between the control side and load side. A solid state relay is applied to control high current load with inputting a small control signal. Compared with the electromagnetic relay (EMR), the solid state relay is more reliable, non-contact, long life, high speed and little interference, and it has been widely used.
ATO provides single phase and three phase solid state relays, including DC-AC and AC-AC, with load current from 10A to 120A. In addition, compact-size industrial solid state relays are provided with DC control AC, load current ranging 60 amp, 80 amp, to 350 amp. More details are as below and you can select a most suitable one to switch on/off your facilities or machines.
