SUITABLE FOR R&D OF NEXT-GENERATION ENERGY SYSTEMS SUCH AS SOLAR CELL AND SMART HOUSE

VDD series are high power and variable output DC-DC converters which can be operated on DC.
Because the DC operation, VDD is most suitable for many applications.
For example, it is the best choice for R&D of next-generation energy systems and anti-disaster measure systems, such as Smart house in which electricity is supplied as DC mutually between home rechargeable batteries and EVs, and Voltage adjustment when driving DC electronic equipment by emergency large rechargeable batteries.
Furthermore, you can install VDD into your system easily because it is equipped with various digital interfaces such as LAN and USB.*

  • Adaptors will be needed additionally. And, -LGob option will be needed if it will be used under specific condition.

  • Compact and high power 0.8kW to 5kW
  • Ideal for research and development with low noise switching method.
  • Wide input voltage is available.
  • Various operations by connecting multiple power supplies, such as master/slave, is possible.
  • VOL adopt Large four-digit monitor display for both voltage and current, which contributes to precise monitoring with better recognition.
  • Operability and safety are improved with new features of key-lock function and acceleration rotary encoder, that increment will vary by speed of rotation.
