RCCx-xxx Reactive Current Control0 pages
Cognito Quam Industrial Electronics, Control, Robotics and Automation RCCx-xxx Reactive Current Control The RCCx reactive current control detects reactive current in a single- or three-phase line and closes its output contacts if above the set limit. It can thus dynamically compensate low inductive power factor lines by signaling the need to switch capacitors in and out of the line. It is very simple to install and adaptable to all power factor compensation applications. Current transformer input terminals Line input terminals Output relay Activation current potentiometer DIN rail latch Three phase reactive current control RCC3-xxx. The RCC measures the reactive current in a single-phase (RCC1-xxx models) or three-phase (RCC3-xxx models) system and closes the 12 A output contacts when the monitored reactive current is above the preset value. The current is detected with a current transformer (CT) in one of the phase lines with a maximum response time of 30 seconds. The RCC response time makes it particularly suitable to activate contactor switched capacitor banks in dynamically compensating low-duty or variable loads such as: Lifts, Օ Conveyors, Compressors, Օ Pumps, Fans, and Օ Office lighting. r.1 Jan12 Copyright © 2011-2012.
