CR Magnetics CR4480-5 Three-Element Average RMS AC Current Transducer

The CR4480-5 from CR Magnetics is a three-element average RMS AC current transducer that converts sensed AC current into a 4-20 mA DC signal. It provides an analog 4-20 mA loop output for direct integration with standard instrumentation and control systems. The three-element arrangement delivers an average RMS representation of the monitored current, helping maintain stable readings under varying waveform shapes and load conditions. As part of CR Magnetics’ current transducer family, the CR4480-5 combines compact form with a robust electrical interface suitable for industrial environments and demanding installations. This device is designed to monitor AC line currents in electrical systems and feed a loop-powered signal to PLCs or other process-control equipment that accept 4-20 mA inputs.
