ATPR "E-OUT" SERIES

Current Transducers

ATPR RMS AC current transducers combine a current transformer with a true RMS signal conditioner in a single package. ATPR Series produce a 0–5 or 0–10VDC RMS output on distorted waveforms found in the output of variable frequency drives, phase angle fired heating controls and on linear loads in "noisy" power environments. Available in split-core housing only.

True RMS Sensing
  • Sensor output is proportional to the current flowing in the circuit, even with high distortion or harmonic loads
  • Compatible with most automation systems
External Powered
  • Provides the highest degree of accuracy and response
Range Selectable
  • One sensor covers a wide variety of loads
  • Field selectable ranges keep spare part inventory at a minimum and allow for changes in load conditions
Split-core Case
  • Simple installation, release the latch and snap over the conductor
DC Voltage Output
  • Perfect for data acquisition systems, panel meters or controllers with only voltage inputs available
Built-in Mounting Feet
  • Simple, two-screw panel mount or attach with optional DIN rail brackets.*
  • Designed for UL and CUL; CE Approval
  • Accepted worldwide
*See DIN Rail accessory page for panel mounting kit.
