Order now Distributor List Contact Sales DVM - Voltage Sensors The DVM product series comprises a compact range of voltage sensors designed for high and medium voltage measurements in industrial and traction applications. These sensors are crafted for the electronic measurement of voltages, including DC, AC, and pulsed voltages, with galvanic separation between the primary and secondary circuits.

Specifically tailored for medium and high voltage measurements ranging from 600 to 4200 VRMS, the DVM voltage sensors feature a unique compact design and deliver exceptional overall accuracy. 

Powered by our patented insulation digital technology, the DVM components seamlessly blend low consumption, very high accuracy, and minimal temperature drift.

Within the DVM series, various voltage sensors cater to specific needs, including DVM, DVM-B, and DVM-UI, each with its own set of features.

DVM – Features and benefits FeaturesBipolar and insulated measurement of voltageCurrent output for DVM parts, Voltage output for DVM-B sensorsPrimary input and output connections with M5 studs or threaded insertsCompatible with LV 100 seriesBuilt-in device. The DVM-B voltage sensors feature input connections with M5 studs and output connections with M5 threaded inserts.

In contrast, the DVM-UI electronic components come with their own set of features:

Unipolar and insulated measurement from 0 to UP N4-20 mA instantaneous outputUnipolar power supplyPrimary input and output connections with M5 studs. Main characteristicsCompact design (30% smaller, 25% less volume)A unique design to cover all measuring voltage ranges 600 to 4200 VRMSHigh level of insulation test voltage: 12 KVRMS / 50 Hz / 1 minHigh level of RMS voltage (5 kV) for partial discharges extinction @10 pCExcellent overall accuracy:+/- 0.5% of Vpn at + 25°C+/- 1% of Vpn over the operating temperature rangeHigh bandwidth (short response time): 13 KHz (-3 dB) (50 µs)Low consumption and low lossesVery low sensitivity to common mode voltage variationsFast delay timeLow temperature driftHigh immunity to external interferences. Typical applications of the DVM Series

DVM sensors are commonly used in both railway settings (including fixed installations and onboard trains) and industrial applications. It is typical to find DVM sensors in the following applications:

AC variable speed and servo motor drives Static converters for DC motor drives Battery supplied applications Uninterruptible Power Supplies (UPS) Switched Mode Power Supplies (SMPS) Power supplies for welding applications Renewable Energy (Solar and Wind) Single or three phase inverters Propulsion and braking choppers Propulsion converters Auxiliary converters High power drives Substations

The DVM-UI components are specifically designed for particular application fields, showcasing optimal performance in substations and trackside applications.
