The Carlo Gavazzi RGC1P solid state relay is a series of solid state contactors with integrated heatsink that allows control of output power of 1-phase loads with an analog control input. The RGC1P offers a wide range of current and voltage ranges. Local setting by an external potentiometer is also possible. Switching modes, selectable through a front knob, allows phase angle control, full cycle control, advanced full cycle control specific for short wave infrared heaters and soft starting for limiting inrush current of loads with a high temperature coefficient. The output of the RGC1P is protected against overvoltages by means of an integrated varistor across the output. Two front LEDs indicate the status of the load and control.
