LEM AHR Series Split Core AC/DC Hall Effect Sensor

Compact and versatile transducers for high AC and DC currents from 500 to 2000A True RMS with signal conditioning. Choice of output types: 4-20 mA, 0-5 V or 0-10 V, Bandwidth: DC 20..6000 Hz

Features

  • Split Core
  • VFD and SCR waveforms current measurement
  • True RMS output
  • 4-20mA current output
  • Busbar mounting
  • Eliminates insertion loss
  • Isolated plastic case recognised according to UL94-V0

Advantages

  • Large aperture for cable or busbar up to 104 x 40mm
  • High isolation between primary and secondary circuits
  • Easy installation

Applications

-AC Power Supplies or Motors

True RMS sensing - the most accurate way to monitor power supply or input power

-VFD Controlled Loads

VFD output indicates how the motor and attached load are operating

-SCR Controlled Loads

Accurate measurement of phase angle fired or burst fired(time proportional) SCR's and switch mode rectifiers. Current measurement gives faster response than temperature measurement.

-Renewable Energy Installations or Backup Batteries

Continuous condition monitoring allowing automatic failure detection and prediction

-Application Domain
