  • OVERVIEW

    Enjoy Linearity Accuracy Up To 1% for Your Energy Monitoring Needs

    A small 5-75 AMP split-core AC Current Transformer (CT) mounted around a current carrying wire to measure AC amperage. This CT provides a .333 Volt AC output proportional to current flow and is used with HOBO data loggers via the FlexSmart TRMS module 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

    Features

    • Output 0.333 Volt AC at rated current
    • Linearity accuracy ± 1%
    • Accuracy at 10% to 130% of rated current
    • Split-core design for fast, easy installation
    • 8 ft. (2.44m) 24 AWG twisted pair leads
    • 0.40″ (10.15mm) opening
  • SPECIFICATIONS
