The RCTi & RCTrms 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 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 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 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.

Current output options - converting RCTi and RCTi3ph to 1A or 5A current output

The RCT1A current probe has a 1A secondary current output - current sensing is based on a  Flexible Core Loop.   

The RCT1A is a 1A output Flexible current probe.   The TA module is used for interfacing existing RCTi and IRF current probes to existing 1A or 5A metering circuits.  The TA module converts the RCTi/IRF voltage output to 0-1A or 0-5A signal.  Unlike conventional CTs, there are no open circuit hazards, these are ideal with installations in confined spaces.  The RCT1A, RCT/TA5V-5A combination simplifies installation and eliminates the need for expensive LV/HV plant shutdown.
Models from 100/1A to 50000/1A, Accuracy Class 1 (1%) at 5VA. UL/CSA pending
