This series gives the possibility to control output power of 3- phase loads with an analog control input. The RGC2P is a 2- phase switching product whilst the RGC3P switches all 3 phases. Input types cover a wide range of current and voltage ranges. Local setting by an external potentiometer is also possible. Switching modes cover phase angle control, distributed full cycle control and soft start for limiting inrush current of loads having a high temperature coefficient, such as short wave infrared heaters. Detection of mains loss, load loss, SSR short circuit and overtemperature is integrated in some models. Alarm condition is signalled through an EMR output and is visually indicated by the alarm LED. Additional LEDs indicate input and load status.
