LEM introduces the DVL series for insulated nominal voltage measurements in traction applications. This family of devices spans the range from 50-2000 VRMS. Despite achieving high levels of isolation with a safety insulation voltage of 8.5 kV, the transducer is compact, measuring only 137.8 x 63 x 64.3 mm. 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. The supplier 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 voltage transducer also makes it an excellent fit for a broad range of small-to-medium voltage measurements in industrial markets. The transducers measures voltages by a direct connection on its primary side, transfers the data across an internal isolation barrier and outputs a current from its secondary side that is proportional to the measured voltage. Its measurement frequency bandwidth (-3dB point) is 14 kHz and the product consumes 20 to 25 mA when power supplied under +/-24 VDC (power supply range from +/- 13.5 to +/- 26.4 V), a power saving of 30% relative its predecessors. 2 kinds of current output ranges are possible either +/- 50 mA, or the standard industrial current-loop range of 4 to 20 mA.
