Fotek Series SSR Semiconductor Relay Technical Specifications

1. Overview information of Fotek SSR semiconductor relay
Fotek SSR Semiconductor Relay (made in Taiwan) is called SSR Semiconductor Relay (Solid Stay Relay), this is a commonly used solid state relay.SSR relays are often designed as a simple on-off switch with a power terminal and a load terminal, switching when an external control signal is transferred to the relay via a different terminal. When a signal is present, the conversion occurs very quickly and the load is powered, usually using a Mosfet power transistor.
The SSR semiconductor relay is a switching relay that does not require the use of any mechanical parts, so there is no sparking phenomenon like many other types of relays, no interference, no noise. High durability and longevity, anti-vibration, anti-corrosion, low input power consumption.
