LEM introduces the DVL series of compact, power saving voltage transducers for the traction market

Key points: 30% reduced power consumption, improved accuracy and temperature stability----- Fully-isolated nominal measurement of 50-2000V DC, AC or pulsed----- Compact, light and robust package----- Combines 8.5 kV insulation with unmatched immunity against electromagnetic disturbances----- Meets latest IRIS requirements for rail traction applications

LEM introduces the DVL series for insulated nominal voltage measurements in traction applications. This family of devices spans the range from 50-2000 VRMS and incorporates LEM's proven and patented insulating technology. It is fully compatible with previous generations of transducers in terms of both functions, performance and footprint and offers new high levels of accuracy and temperature stability.

LEM developed the DVL to be fully compliant with the International Railway Industry Standards (IRIS), providing engineers in the railway industry, who are working with both rolling stock and

sub-stations, with a versatile new transducer that is equally applicable to measuring network voltages, or the main converter DC link on-board trains. The feature set of the DVL voltage transducer also makes it an excellent fit for a broad range of small-to-medium voltage measurements in industrial markets.

In addition to using less power, the DVL, in its small outline, is 30% lighter than transducers already in the market. Other key features include a high level of partial discharge extinction voltage, and compliance to a range of internationally-recognized safety standards in addition to its adherence to IRIS specifications. It also exhibits a fast response time, and excellent noise immunity. A range of connection configurations, on both the primary and secondary side, increases flexibility for the user.

Designed by LEM in accordance with the latest standards applicable for traction, the DVL utilizes materials that comply with all relevant fire and smoke requirements, that are mandatory in railway applications. It is CE marked and is supplied with a five-year warranty, as are all LEM railway products.
