Overview

The DCflex is an easy to use, low cost, thin and clip-around DC current probe. It is suitable for measuring large DC currents of >2kA.

The DCflex takes a single shot measurement of the DC current with a typical accuracy of ±1%. It is important to understand that the DCflex does not provide a continuous measurement of DC current.

The DC current is displayed on a small LCD display on the front of the electronics enclosure. Alternatively the output can be viewed on a DMM or oscilloscope via a BNC socket on the front of the enclosure, a feature that is useful if the DC current measured has a ripple component which needs to be measured.

Press the reset button Null the offset to zero

Features

  • Traceable calibration (certificate included)
  • Integral display so no need for external meters or oscilloscopes (though BNC output also provided)
  • Fully galvanically isolated measurement
  • Thin, flexible, clip-around coil easy to insert in confined spaces
  • Large circumference coils capable of being installed around very large bus-bars or cable bundles.

Applications

Power (Quality) Measurements

Some typical applications include

  • Metal smelting plants
  • Cathodic protection
  • Hydro-generation
  • DC link (large inverter motor drives)
  • Plating plants
  • Verifying the performance of large dc shunts or Hall Effect transducers that are in-situ in existing plant.
