The RCCS3 switches measure the reactive current in a single- or three-phase line system and activate three 8 A solid state switches to connect three compensating capacitors in and out of the three phase line. The current is detected with a current transformer (CT) in one of the line phases and the sampling period is selectable from 4 to 32 seconds.
The RCCS3 response makes it particularly suitable for fast dynamic power factor (PF) compensation of frequently-started, low-duty or variable loads such as lifts, conveyors, compressors, pumps and fans.
Each switch is activated when the detected reactive current is above the respective set value as determined at the activation potentiometer. Switch activation/deactivation happens at every sampling instant as set at the DIP switch.
The RCCS3 is a fully protected, digitally-controlled unit, simple to install and adaptable to all power factor capacitor compensation applications. The only other parts required to build a complete power factor correction system are the current transformer and the compensating capacitors.
