Our ProductsLV Voltage Optimisation

Variable LV Voltage Optimisation

Powerstar MAX is an ‘electronic-dynamic’ or variable voltage optimisation system which provides a stable voltage supply through the use of intelligent electronic controls to automatically adjust and optimise the voltage to a constant level. The primary benefits of an optimised and stable voltage supply are:

 

Variable voltage optimisation

SAVE: Money on electricity costs

PROTECT: Corporate Social Responsibility (CSR) and company reputation

REDUCE: Financial risks, lower capital costs and increase the bottom line

CUT: Carbon footprint and CO2 emissions

A Stable Voltage Supply Through Powerstar MAX

Powerstar MAX systems clean, condition and stabilise the incoming power supply, setting the voltage to a level which closely meets the requirements of the on site electrical equipment and maintains it at this level irrespective of fluctuations in the incoming voltage profile. The benefits of voltage optimisation through Powerstar MAX are:

  • Decreased energy consumption
  • Reduced wear on electrical equipment
  • Lower carbon emissions
  • Significant savings on electricity bills
  • Added security and stability
  • 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 system 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.

Further Benefits of Voltage Reduction

Powerstar MAX 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
  • Additional savings opportunities
  • Typical return on investment of 2-3 years
  • Reduced harmonic distortions
  • Improved power factor
  • Improved phase balancing
  • Intelligent real-time interface
  • An innovative system with a patented design
  • No maintenance solution
  • Up to 15 years warranty and estimated 50-year lifespan

 

A Solution for Unstable Voltage Profiles

If a company is experiencing high levels of incoming voltage with a fluctuating voltage profile, high night loading or has a requirement for additional electrical security then a Powerstar MAX voltage optimisation system could present the most effective solution.

LITE and MAX

Powerstar MAX is more than just a voltage stabiliser, it is an electronic-dynamic (variable) voltage optimisation system which matches the incoming voltage to meet the operating requirements of onsite electrical equipment and maintains it at a constant level.

A stabilised voltage output is achieved through the use of intelligent, electronic controls that automatically adjust to create a stable profile, irrespective of the fluctuations or volatility of the incoming supply.

The Powerstar MAX system can be manufactured from 28KVA for smaller sites up to 3MVA for large businesses, thus providing a viable voltage stabiliser and electronic optimisation solution for a range of applications.

An example of voltage optimisation through Powerstar MAX is visualised on the chart (below) with the voltage profile through a Powerstar MAX voltage optimisation system characterised by the amber line.

LITE vs MAX

Sites with a more stable voltage profile could benefit from ‘fixed’ voltage optimisation system provided by Powerstar LITE, as represented by the blue line in the chart. Although the Powerstar MAX, along with its voltage stabiliser benefits, also offers additional savings opportunities.

Additional savings are available as Powerstar MAX generates negative power (back EMF), whereby excess voltage is returned in direction of the supply, this reverse current is ‘real energy’ which has a direct impact on the electrical load and as a result reductions in power consumed can be seen by actual kWh savings.

 

Is Powerstar MAX Right for My Business?

Powerstar MAX is ideal for companies with the following profile:

  • Operates a low voltage (LV) supply only
  • Has a high level of incoming voltage
  • Has a fluctuating or volatile incoming voltage profile
  • Has critical site equipment that requires additional security
  • Has high night loads and electricity is still consumed as other uses reduce demand

Powerstar MAX can be integrated with an amorphous core HV/LV transformer (Powerstar HV MAX) and with the VIRTUE energy storage system depending on a client’s needs.

Powerstar MAX systems have provided significant savings for healthcare estates, hotel and leisure facilities, supermarket chains, data centres and cold storage sites.

If electronic-dynamic optimisation through Powerstar MAX does not fit your requirements then fixed optimisation through Powerstar MAX may represent an alternative 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 approach.
