Brief Introduction of Three - phase AC Solid State Relay
2017/02/25
Three-phase AC solid state relay (hereinafter referred to as three-phase SSR) is a three-phase single-phase AC solid-state relay as a whole, and a single input to the three-phase load for direct switching, can easily control the three-phase AC motor, Three-phase load.
Three-phase ordinary SSR is a three-way thyristor as A, B, C three-phase output switch contacts, current rating 10A, 25A, 40A, voltage level 380V, 480V two series, three-phase enhanced SSR is a three-phase anti-parallel one-way thyristor as A, B, C three-phase output switch contacts, current levels are 15A, 35A, 50A, 70A, 120A, 150A, voltage class points 380V, 480V.
Mainly used for three-phase AC power supply automatic control equipment such as: industrial furnace, electric oven, water pumps, fans and so on.
