VTF serie

POLYLUX’S VTF serie

Three phase Stabilizers

The VTF series is made up of three-phase automatic voltage stabilizers with phase control that have a rating range as from 5kVA up to 150kVA.

With this equipment, a stable output voltage of 400V is achieved with a variable input voltage (supply from the electric company or another generator) of 400V±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.

VTF models are manufactured without isolating transformers.
