The RCT1A flexible current probe & TA5V-5A converter allows connection to existing 1A or 5A CT metering circuits - using flexible rope-type current sensor

 These probes have great bandwidth ensuring accurate measurement even with harmonically distorted wave shapes. For all RCT1A/RCT models, a NIST, NAVLAP, NPL (UKAS) factory traceable calibration certificate and certificate of conformance is supplied. UL/CSA approved materials are used throughout. Three phase and single phase flexible AC current sensors (rope sensors) are available for fast installation in confined spaces, eliminating the need for Electrical Supply Shutdown.  Available outputs are 1A @ 2.5VA and 5A @ 0.5VA, this means long cable lengths from current sensor to signal conditioner allow these low VA ratings to be used, even when feeder cable to energy meter distances are large (up to 98 feet / 30 meters)

The RCT1A and RCT5A flexible current probes have 1A or 5A secondary current output - current sensing is based on a  Flexible Core Loop.   Models from 100/1A to 50000/1A, Accuracy Class 1 (1%) at 5VA. UL/CSA pending


 

TA5V-5A and TA5V-1A module used for converting RCTi voltage output to 5A or 1A





Model TA5V-5A output module

The TA module is used for interfacing existing voltage output RCTi and IRF flexible 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.
