October 28, 2013 - Carlo Gavazzi releases RGC2P and RGC3P 3-phase solid state switching controllers that deliver output power in proportion to the control input voltage or current as well as external potentiometer.
The RGC2P Series consists of a 3-phase, 2-pole switching device which offers an economical means of switching, because it only switches L1 and L3. The RGC3P Series consists of 3-phase, 3-pole switching devices. Various switching modes are available to cater for different application needs, such as phase angle switching for light dimming; full cycle switching for precise temperature control; and a soft starting version that prevents high inrush currents associated with loads with high cold/hot resistance ratio. The RGC2P and RGC3P Series are available in two frame sizes: 54mm or 70mm wide. RGC2P, the 2-pole switching device, offers four current ratings of 15, 25, 40 and 75AAC per pole.
While RGC3P, the 3-pole switching device, offers three current ratings of 20, 30 and 65Amps per pole. The optional monitoring feature offers the possibility of detecting the status of mains and load, as well as for internal controller failures: open or short circuit and overheating. Alarming is implemented with an LED indication and a relay output.
