Description

The RCTi sensors convert ac current to an isolated 0-5V voltage or 4-20mA current loop. TA5V-5A allows compatibility with existing 1A or 5A CT metering circuits. Both offer a choice of proportional (rms) and instantaneous outputs. The available RCT ac current ranges are 0-100A to 0-50,000Apk. Both RCTi and RCTrms provide accurate measurement over a wide bandwidth ensuring precise measurement even with harmonically distorted wave shapes - using a flexible clip-on sensing coil. The RCTs are available as single and three phase models.

The RCT sensors can provide all popular process control voltage and current loop outputs along with custom output options. Because the ac current sensors are split core, installation is possible without shutting down the electrical supply - saving down-time costs. Typical applications are retrospective energy monitoring in factories, offices, process control systems like PLC, SCADA Data logging systems, all where power, energy and ac current monitoring is important. Typical loading situations are factories, shops, offices, 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.
