0-100, 0-150 and 0-200 Amp Ranges, Top Terminals

Features

  • True RMS Output
    - True RMS technology is accurate on distorted waveforms like VFD or SCR ouputs
  • Jumper Selectable Ranges
    - Reduces inventory
    - Eliminates zero and span pots.
  • Isolation
    - Output is magnetically isolated from the input for safety
    - Eliminates insertion loss (voltage drop)
  • UL, CUL and CE Approval
    - Accepted worldwide


Applications:

  • VFD Controlled Loads
    - Monitoring VFD output indicates how the motor and attached load are operating.
  • SCR Controlled Loads
    - Accurate measurement of phase angle fired (time proportioned) SCRs
    - Current measurement gives faster response than temperature measurement
  • Switching Power Supplies and Electronic Ballasts
    - True RMS sensing is the most accurate way to measure power supply or ballast input power.

Product Information

ATR Series Current Transducers combine a current transformer and a True RMS signal conditioner into a single package. The ATR Series provides True RMS output on distorted waveforms found on VFD or SCR outputs, and on linear loads in “noisy” power environments. Available in a solid or split-core case.

Selecting the right transducer: The current waveform of a typical linear load is a pure sine wave. In VFD and SCR applications, however, output waveforms are rough approximations of a sine wave. There are numerous spikes and dips in each cycle. ATR transducers use a mathematical algorithm called “True RMS” which integrates the actual waveform over time. The output is the amperage component of the true power (heating value) of the AC current waveform. True RMS is the only way to accurately measure distorted AC waveforms. Select ATR transducers for nonlinear loads in “noisy” power environments.

Designed to provide an analog current reading for monitoring, data logging and panel meter applications, these transducers offer a choice of 0–5VDC, 0–10VDC or 4–20mA average responding or True RMS outputs. Self-powered and split-core options make these a cost-effective choice as a PLC input in motor status applications or where VFDs are involved
