Onset Mini Split-core AC Current Transformer Sensor

Measurement Category: Electric & Power
Operating Environment: Dry Enclosed Space
Version(s): Available with 20 Amp, 10 Amp, 50 Amp, 75 Amp and 5 Amp current ratings.


The small size split-core AC Current Transformer (CT) is mounted around a current carrying wire to measure AC amperage. This CT provides a 0 to .333 Volt AC output proportional to current flow. Has window opening of 0.4 inch. Interfaces with Onset data loggers via the FlexSmart TRMS module and with kWh transducers (WattNodes) for True RMS measurement of sinusoidal and non-sinusoidal waveforms.
