Voltage transducer offers insulated measurements
LEM introduces the DV series voltage transducer for insulated voltage measurements from 1200-4200 VRMS
Engineers in the railway industry (including rolling stock and sub-stations) can use the transducer for measuring network voltages and the train's main converter DC link.
The product is also adapted for the industrial markets for high and medium voltage measurements.
With a low current consumption of 19-23mA, a large frequency bandwidth of 12kHz and safety insulation voltage of 18.5kV, the DV voltage transducer meets the demands of modern rail systems and fulfils all new EMC requirements.
Other key features include a high level of partial discharge extinction voltage, adherence to safety standards, high quality and long life.
The trend in the railway market is to save space and improve performances.
On the other hand, the latest standards make increasing requirements for higher insulation and partial discharge extinction levels in order to guarantee safety, as well as better immunity against external electrical, magnetic and electromagnetic fields for EMC protection.
The DV has been designed to meet both these conflicting demands.
The DV is Class 1 certified and materials utilised comply with the fire and smoke requirements, which are mandatory in railway applications.
The DV is CE marked and is supplied with a five-year warranty.
