Our ProductsLow Voltage Optimisation

Fixed LV Voltage Optimisation

Fixed voltage optimisationThe Powerstar LITE ‘fixed’ voltage optimisation system provides a set level reduction matched from the incoming supply and administered through a predefined tap range. The solution cleans and conditions the incoming power supply, optimising the incoming voltage by a set amount to match the requirements of the electrical equipment on site. The benefits of voltage reduction through Powerstar LITE are:

  • Regulated voltage to protect on-site electrical equipment
  • Decreased energy consumption
  • Reduced wear and tear on electrical equipment
  • Lowered carbon emissions
  • Significant savings on electricity bills
  • Additional savings through induced negative power (back EMF)

Powerstar deliver a concept to completion ‘turnkey’ solution, offering clients an engineered solution to their sustainability challenge. All Powerstar systems are fully designed and manufactured in the UK to meet the requirements of each site and are not off the shelf units. Through this approach to voltage optimisation we are able to produce the correct application for each building, therefore, delivering maximum efficiency and savings for clients. This is backed by a 100% savings guarantee, reducing any perceived financial risk of the project.

Further Benefits of Voltage Reduction

Powerstar LITE is fully designed and manufactured in the UK and, as a result, clients can be assured that the solutions are manufactured to the highest quality to ensure the highest efficiencies. All systems are backed by a 100% savings guarantee, in addition, clients will also benefit from:

  • Average 8 – 10% savings on annual electricity consumption
  • Reduced harmonic distortions
  • Improved power factor
  • Improved phase balancing
  • No maintenance solution
  • A patented design
  • Up to 15 years warranty and estimated 50-year lifespan
  • Typical return on investment of 2-4 years


Applications of Powerstar LITE

If a company is experiencing high levels of incoming voltage with a stable voltage profile, a Powerstar LITE voltage optimisation system could present the most effective solution for voltage management on their site.


For example, if a company was experiencing voltage between 245V-250V, and this was reduced by 15V, the incoming voltage would then operate between 230V-235V.
The Powerstar LITE system can be manufactured from 100Amp (for small commercial systems) up to 3MVA systems for large commercial premises, thus providing a viable voltage management solution for a range of businesses.

An example of voltage management through Powerstar LITE is visualised on the chart (below) with the blue line representing a fixed reduction in the supply voltage.


Sites with unstable or fluctuating voltage, however, would benefit from electronic variable voltage optimisation system provided by Powerstar MAX, which will stabilise the supply voltage to reduce fluctuation (as represented by the amber line in the chart).


Is Powerstar LITE right for My Business?

Powerstar LITE is ideal for companies with the following voltage profile:

  • Operates a low voltage (LV) supply only
  • Has a high level of incoming voltage
  • Has a stable voltage profile

Powerstar LITE systems have provided significant savings for manufacturing and industrial sites, education facilities, office buildings and retail outlets.

If voltage management through Powerstar LITE does not fit your requirements then our ‘electronic-dynamic’ optimisation system, Powerstar MAX may represent a more suitable solution. If your company operates its own HV/LV distribution transformer then optimising voltage at the HV side through Powerstar HV MAX may represent a more effective voltage management approach.
