5VA rated output drives long cable runs up to 50ft/15.2m
The CTA flexible current transformers are the world's first flexible 'clip-on' current probe with a 5A output, allowing compatibility to existing 5A metering circuits. Unlike conventional CTs, there are no open circuit hazards - ideal for retrospective metering projects and installations in confined spaces where installation of conventional iron core CTs is not possible. The CTA flexible current sensor also simplifies installation and eliminates the need for expensive LV/HV plant shutdown. In addition, these modules are used to convert any voltage output current measuring device to a 1A or 5A secondary.
The CTA flexible current transformers convert ac current to an isolated 0-5A current with available ranges from 100A to 10,000A. Because the current sensors are flexible split core, installation is possible without shutting down the LV electrical supply, avoiding expensive down-time costs. Typical applications are retrospective energy monitoring in factories, offices buildings, process control data logging systems, where power, energy and current monitoring is important. Typical applications are factories, offices buildings, ac/dc VFD drives, welding, power conversion and power distribution. For all CTA current sensor models, a NIST/NPL (UKAS) traceable calibration certificate and certificate of conformance is supplied. All CTA sensors use UL94V0 or CSA approved materials. The CTA flexible current sensors are suited to permanent or semi permanent installation. The coil sensor is durable, lightweight, flexible and will easily clip-around a power cable. The 5A output from the CTA current sensor connects direct to installed metering, rotary metering or current transducers.
