LEM DH Current Transducers

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 2000A. 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.

The DH series has been designed to measure DC currents and their polarity. It offers a choice of primary current measurement ranges from 500A to 2000A and provide an absolute accuracy better than 1 percent of the nominal current value. The new transducers output the bipolar measurement value through an industry standard 4-20mA output. They feature a loop-powered circuit (adapted to 20-30 VDC power supplies) that reduces installation costs by minimizing 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. The performance and reliability of the DH transducers have been validated in a number of beta installations where the transducers monitor charge and load currents of standby batteries in large UPS systems as well as in telecommunication base band antennas.
