VK series

POLYLUX’S VK series

Single phase stabilizers

The VK series is made up of single-phase automatic voltage stabilizers that have a rating range from 5kVA to 50kVA.

With this equipment, a stable output voltage of 230V is achieved with a variable input voltage (supply from the electric company or another generator) of 230V±20%.

Some of its utilities:

  • Power equipment sensitive to voltage variations, such as computer and electronic equipment or telecommunications equipment.
  • Valid for installations in which the line voltages experiences fluctuations during the day.
  • Not valid for sudden voltage changes such as company maneuvers.

VK models are manufactured without isolating transformers..
