Product Description

The small size 1-5 AMP 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 and is used with Onset loggers via the FlexSmart TRMS module (Part # S-FS-TRMSA-D) and with kWh transducers (WattNodes) for True RMS measurement of sinusoidal and non-sinusoidal waveforms. The result is an accurate current measurement for many types of electrical equipment.
