Powerstar fixed voltage optimisation system
The Powerstar range of fixed voltage optimisation systems provide a set level reduction across a predefined tap range. 
The optimised voltage will match the incoming voltage profile, albeit reduced by a set amount.

What are the Benefits?

Powerstar fixed voltage optimisation systems are effective energy savings solutions for companies looking to reduce electricity consumption and associated carbon emissions. The benefits of installing a Powerstar fixed voltage optimisation system are:

  • Average savings in electricity consumption of 10%-12%
  • Reduction of carbon emissions
  • Increased life expectancy of equipment and reduced maintenance costs
  • Can significantly reduce harmonics
  • May improve Power Factor
  • Capable of improving phase balancing
  • Manufactured in the UK, with a patented design
  • Guaranteed savings

Is Powerstar right for my business?

Powerstar fixed voltage optimisation systems are ideal for companies with the following profile;

  • The site has a low voltage (LV) supply only
  • The site has a high level of incoming voltage
  • The site has a stable voltage profile
  • Powerstar fixed voltage optimisation systems have made significant savings in manufacturing and industrial sites, education facilities, office buildings and retail outlets.

If the Powerstar fixed voltage optimisation system does not fit your requirements then have a look at our Powerstar MAX and Powerstar HV MAX solutions.

What is fixed voltage optimisation?

fixed voltage optimisation and variable voltage optimisationPowerstar fixed voltage optimisation systems,
match the voltage profile of the original supply but will reduce this by a set amount to the optimum level for the site.

An example of this is visualised on the chart (right) with the voltage profile through a Powerstar fixed voltage optimisation system characterised through through the blue line.

Sites with more unstable or fluctuating voltage would benefit from electronic variable voltage optimisation system provided by Powerstar MAX, as represented by the green line in the chart.

Product range and specifications

The PowePowerstar fixed Voltage Optimisationrstar fixed voltage optimisation range is available in a range of sizes from 50kVA to 3,000kVA, and with 5 to 25V tap settings.

Additional options include harmonic mitigation winding, HMI (Human Machine Interface), Automatic voltage reduction bypass and manual switch bypass.

The Powerstar systems are not off the shelf solutions and are engineered to suit the voltage characteristics of each site.

Please see our dimensions table for typical case sizes for the Powerstar voltage optimisation systems.
