Three-phase and single phase sensors
The RCTi & RCTrms sensors convert ac current to an isolated 0-5V voltage, 4-20mA current loop. Optional 1A or 5A outputs ensure compatibility with existing CT metering circuits. Both offer a choice of proportional (rms) and instantaneous outputs. The available RCT ranges are 0-250A to 0-50,000Apk. Both RCTi and RCTrms provide accurate measurement over a wide bandwidth ensuring precise measurement even with harmonically distorted waveshapes – using a flexible clip-on sensing coil. The RCTs are available in single and three phase.
The RCT sensor can provide all popular process control voltage and current loop outputs along with custom output options. A range of through hole or split core sensors means that connection is possible without shutting down an operating feeder. Typical applications are process control systems like PLC, SCADA Data logging systems, where power, energy and current monitoring is required. Typical loading situations are ac/dc VFD drives, ultrasonics, welding, power conversion and power distribution. For all RCT models, a NIST/NPL (UKAS) traceable calibration certificate and certificate of conformance is supplied. All RCT sensors use UL or CSA approved materials.
