DVC - Compact voltage sensors
The DVC product series comprises a compact range of voltage transducers designed for both industrial and traction applications. Tailored for fully isolated nominal measurements of 1000 V DC, AC, or pulsed voltages, these sensors incorporate galvanic separation between the primary and secondary circuits.
The main advantages of DVC voltage sensors lie in their compactness, lightness (22 g for DVC-P and 57 g for the rest of the DVC series), and robust packaging. DVC transducers are primarily intended for Panel and Rail Din mounting. Conversely, DVC-P allows for PCB mounting.
Every electronic component in the DVC range complies with the latest industrial standards and IRIS requirements for rail traction applications. The DVC components operate using isolation amplifier technology.
DVC – Features and benefits
Features
- Bipolar and insulated measurement up to 1500 V

- 4-20 mA instantaneous output (unipolar power supply)
As mentioned earlier, the DVC-P Series is specifically engineered for PCB mounting. It comes with 8 pins and is designed with a 5 V unipolar power supply.
Main characteristics
- Low consumption and low losses
- Compact design
- Very low sensitivity to common mode voltage variations
- Excellent accuracy (offset, sensitivity, linearity)
- Fast delay time
- Low temperature drift
- High immunity to external interferences.
Typical applications
DVC sensors are commonly utilized in both railway environments, including fixed installations and onboard trains, as well as in various industrial applications. These sensors are typically found in applications such as:
- AC variable speed drives 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
- Single or three phase inverters
- Auxiliary converters
- Substations
