Split-core current transducers

26 November 2008 Passive Components

Complementing LEM’s range of products for advanced battery management applications, the new DH family of DC current transducers offers precise measurement of bipolar currents up to 2000 A.

Measuring only 174 x 86 x 54,1 mm, these compact split-core transducers combine Hall-effect technology and signal conditioning in a single housing with a large rectangular sensing aperture for non-contact measurement (supporting up to 104 x 40 mm busbars or Ø 40 mm cables).

The DH series has been designed to measure DC currents and their polarity. It offers a choice of primary current measurement ranges from 500 A to 2000 A and provides an absolute accuracy better than 1% of the nominal current value.

The transducers output the bipolar measurement value through an industry standard 4–20 mA output. They feature a loop-powered circuit (adapted to 20–30 V d.c. power supplies) that reduces installation costs by minimising the wiring and connections required.

Applications include management of UPS systems and standby batteries, DC power generation and distribution as well as monitoring DC motors and process control systems.
