Powerstar is a voltage optimisation product designed and manufactured by EMSc UK Ltd. Powerstar is the flagship product in the EMSc catalouge, a voltage optimisation system that optimises the voltage supply to buildings and equipment. Typical savings are from 8% to a recorded 26% reduction.
Voltage optimisation is an energy saving technology that is installed in series with the main electricity supply to systematically optimise, regulate and clean the incoming power to bring the voltage supplied into a building in line with what is required by equipment, machinery and appliances.

Voltage optimisation is beneficial when the electricity supply to a site is at a higher voltage level than needed, resulting in excessive energy consumption and high electricity bills.

Voltage optimisation should not be confused with step-down transformers or simple voltage stabilisers which only reduce the voltage and do not offer the energy saving benefits of a true voltage optimisation system.

Powerstar are a unique range of market leading voltage optimisation systems, and the only solution with a patent on its design. Powerstar has been fully manufactured in the UK for over 14 years and has thousands of installations throughout the world.

Types of voltage optimisation

The Powerstar range of voltage optimisation systems consists of Powerstar, Powerstar MAX, Powerstar HV MAX and the recently launched energy storage systemPowerstar Virtue.

The most appropriate type of voltage optimisation system for a site will initially be determined by understanding if a company operates either its own HV/LV (distribution) or a low voltage (LV) supply. There are other factors, such as the volatility of the incoming voltage profile, the amount of secure equipment on site and the nature of the businesses operation, which will determine if a fixed or electronic-dynamic (variable) system is best suited to the site.

New innovations in voltage optimisation also allow for the energy saved through a Powerstar VO system to be diverted into an energy storage system to be used when needed, on-site renewable generation can also be integrated into this for maximum benefits.

A voltage optimisation system should not be viewed as an off the shelf solution and a site-specific survey should be undertaken, to ensure that the unit to be installed suits the requirements of the business, in order to maximise any benefits and savings.

Benefits of voltage optimisation

Voltage optimisation is a proven and established technology which has been adopted by companies throughout the world across a range of industries. Powerstar voltage optimisation systems, with their unique design offer unrivalled savings and benefits to clients, including:

  • SAVE: On electricity costs
  • REDUCE: Financial risks; lower capital costs and increased bottom line
  • CUT: Carbon footprint and CO2 emissions
  • PROTECT: Corporate Social Responsibility and Reputation
