Current Transformers

Hand-held and openable
Traditional Current Transformers manufactured as a Clamp-on device for portable applications. Ideal for use with electronic kWh Meters or other devices with an AC Current input. Frequency range extends from 45Hz to beyond 5kHz.
Medium & Large Models are available with 1 Amp, 5 Amp & other outputs, and with single or 3 range primaries. M series mini Clip-on CTs are not available with 5 Amp output. Open circuit protection available on 1 Amp models.
Medium and Large Models are also available with a combined Current & Voltage Output.

The widest range, optimised for modern electronic instruments.
By providing a AC Voltage Output, the Clamp-on CT becomes inherently open circuit protected. A 1 Volt (or even better 100mV) output allows the clamp to operate under optimum conditions. On Medium and Large models, the UE is the basic device, single range only and normally with a 1 Volt output. .U are improved models with outputs up to 5 Volt, and are available as single or 3 range devices.
By standardising on a 1 Volt AC output (or even less) from a Clamp-on CT, the user is assured of the widest range of full scale input currents – from 1 Amp to 3000 Amp.
Identified as xx.U or xx.UE, also available as xx. UM versions for low current measurement. xx.3U etc is a 3 range device, switch selectable.

Special models for Data Logging & Recording.
With an integral AC to DC transducer.
By including an AC to DC converter transducer within the clamp-on CT, and powering the electronics from the measured current, this range of Clamp-on CTs is ideal for use with Data Loggers, Chart Recorders, Computer Data Acquisition Systems, etc – in fact any equipment which has a as a DC Voltage input and needs to monitor and/or log current trends.
Identified as xx.D (1 range) or xx.30 (3 range). xx.DM are designed for lower currents.

For DC and mixed AC plus DC measurement
A Hall Effect cell is mounted within the magnetic circuit of the Clamp-on CT, and the necessary conditioning electronics within the handle. This range of Clamp-on CTs provides an output which is a direct image of the current from DC to 1kHz (or even higher for some models).
.1C models are for OEM use and require an external DC power supply, and are supplied to customer specified input & outputs. .2C and .3C are powered by an integral battery.
The Large battery powered models are all dual range.
Injection Clamps
Instead of measuring a current, clamp-on CTs can be used to inject a signal into an external conductor. Applications include tracing cables or pipework, identifying individual cables, etc. All models can be supplied with custom windings for this application.
