    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, 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.
