The Caloritech™ RA Solid State Relay (Zero Switching) can be used in place of a mechanical contactor or relay. SSRs are optically coupled, isolating control components from the high voltage of the load. SSRs turn on at zero volts and turn off at zero current, eliminating spikes that cause electrical noise (RFI). Since there are no moving mechanical parts, solid state relays are noiseless, can switch as fast as several times per second and still have a life and reliability many times that of mechanical devices.
