DVL FAMILY
Compact and high accuracy voltage sensors for Industrial and Traction applications
DVL - Voltage Sensors
The DVL product family constitutes a compact voltage sensor range designed to ensure high accuracy in both industrial and traction applications. Engineered for the electronic measurement of voltages, including DC, AC, and pulsed voltages, these sensors feature galvanic separation between the primary and secondary circuits.
Tailored for small and medium voltage measurements ranging from 50 to 2000 VRMS, DVL voltage sensors boast a unique compact design, providing a 30% reduction in weight and power consumption. They deliver excellent overall accuracy and are fully compatible with previous generations of transducers, such as the LV100 product family, in terms of performance and footprint.
Operating with our patented insulation digital technology, the DVL components combine low consumption, very high accuracy, and minimal temperature drift.
DVL – Features and benefits
Features
- Bipolar and insulated measurement up to 3000 V
- Current output
- Input and output connections with M5 studs
- Compatible with AV 100 family
The DVL-UI electronic components come with their own features:
- Unipolar and insulated measurement of positive voltage up to 1500 V
- 4-20 mA output
Just like the rest of the DVL family, they are designed with input and output connections with M5 studs. In addition, they are also compatible with LV 100 product family.
Main characteristics
- A unique design to cover all measuring ranges
- Low consumption and low losses
- Compact design
- Good behavior under common mode variations
- Excellent accuracy (offset, sensitivity, linearity)
- Good delay time
- Low temperature variation
- High immunity to external interferences.
Typical applications
DVL sensors are frequently employed in both railway settings (including fixed installations and onboard trains) and industrial applications. It is customary to encounter DVL sensors in the following applications:
- 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
- Renewable Energy (Solar and Wind)
- Single or three phase inverters
- Propulsion and braking choppers
- Propulsion converters
- Auxiliary converters
- High power drives
- Substations
The DVL-UI components are specifically designed for particular application fields, demonstrating optimal performance in substations and trackside applications.
