Powerstar voltage optimisation, proudly made in Britain

Powerstar Voltage Optimisation Systems

  • Powerstar are a range of market leading voltage optimisation systems, with solutions for HV (High Voltage) and LV (Low Voltage) installations.
  • Powerstar are established solutions, fully designed and manufactured in the UK
    since 2001
  • Powerstar are the only voltage optimisation systems on the market with a patented design

Powerstar voltage optimisation systems available in HV and LV range

The Powerstar Range

Powerstar voltage optimisation systems are available in three variations, providing a solutions portfolio that ensure the correct engineering solution is adopted for each site to maximise savings and efficiency:

Powerstar HV MAX

  • Summary: Amorphous core HV/LV transformer with integrated voltage optimisation.
  • Benefits: Average electricity consumption savings of 17%.
  • For use in: Sites operating a (HV) supply with conventional transformer and high voltage.


  • Summary: Fixed voltage optimisation system. Provides a set level reduction across tap range.
  • Benefits: Average electricity consumption savings of 10%-12%.
  • For use in: Sites operating a LV supply with a high, yet stable incoming voltage profile.

Powerstar MAX

  • Summary: Electronic-Dynamic optimisation. Maintains voltage at a constant, stable level.
  • Benefits: Average electricity consumption savings of 12%-15%.
  • For use in: Sites operating a (LV) supply with a high and fluctuating voltage profile.

Engineered solutions

The Powerstar range of voltage optimisation systems are not off-the-shelf products; they represents an engineering solution to the problem of addressing electricity supply issues, over-voltage and high electricity consumption levels.

The Powerstar team will provide a fully supportive approach from the outset to ensure the best voltage optimisation system is identified for each site to ensure optimum savings and carbon reductions are achieved.
