The V Series are a series of solid‑state contactors (with integrated heatsink) that give the possibility to control output power of 1‑phase loads with an analog control input. Input types cover a wide range of current and voltage ranges. Local setting by an external potentiometer is possible. Switching modes, selectable through a front knob, allow 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 having a high temperature coefficient. The output is protected against overvoltage by means of an integrated varistor across the output.
