The PCTi3ph three phase current sensors convert ac current to an isolated 0-5V voltage or 4-20mA current loop. Option TA5V-5A allows PCTi3ph's compatibility with existing 1A or 5A CT metering circuits. Both offer a choice of proportional (rms) and instantaneous outputs. The available PCTi current ranges are 0-100A to 0-500,000Apk. Both PCTi and PCTrms provide accurate measurement over a wide bandwidth ensuring precise measurement even with harmonically distorted wave shapes - using a flexible clip-on sensing coil. The PCTi3ph are available as single and three phase.
The PCTi3ph 3 phase current 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 and expensive busbar / cable reconfiguration. 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 PCTi models, a NIST/NPL (UKAS) traceable calibration certificate and certificate of conformance is supplied. All PCTi sensors use UL or CSA approved materials.
The PCTi3ph and PCTrms3ph are ideal current probes when retrofitting energy meters for LV or MV systems, these split core current transformers are supplied with signal conditioner / transducers. Excellent performance at power frequencies, including harmonics up to 1MHz. Also ideal for VFD drives and induction heating applications. The new PCTi3ph and PCTrms3ph current sensing transducers are suited to permanent or semi permanent installation. The coil sensor is durable, thin, lightweight, flexible and will easily clip-around the conductor. The output from the transducer can be ac voltage (PCTi3ph) or a true rms output (PCTrms3ph). Typically the PCTi3ph is used with energy meters, data loggers, power analyzers, harmonic analysis and in power quality applications. The PCTrms3ph is used in process control Scada Systems and industrial power applications, where a dc output represents the rms ac current.

Current probe has a 1A secondary current output - current sensing is based on a Flexible Core Loop.
The RCT1A is a 1A output Flexible type current probe. The TA5V-5A module is used for interfacing existing PCTi3ph and IRF current probes to existing 1A or 5A metering circuits. The TA5V-5A module converts the PCTi3ph and 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, PCTi3ph and TA5V-5A combination simplifies installation and eliminates the need for expensive bus/feeder reconfiguration or plant shutdown.
Models from 100/1A to 50000/1A, Accuracy Class 1 (1%) at 5VA. UL/CSA pending

The Powertek CTA3ph 5A module can be used with its own economic CTA current sensors, the TA5V-5A module converts the wideband PCTi3ph probe voltage output to 0-5A. In addition, the TA modules are used to convert any voltage output current measuring device to a 1A or 5A secondary. typically used with standard PCTi3ph & IRF current probes.
