Powerstar MAX , Electronic dynamic variable voltage optimizationThe Powerstar MAX range of electronic-dynamic, variable voltage optimization systems optimize the voltage to a constant level.
This is achieved through the use of intelligent electronic controls that automatically adjust and maintain  the voltage to create a stable profile.

What are the benefits?

The Powerstar MAX range of electronic-dynamic, variable voltage optimization systems are effective energy savings solutions for companies looking to reduce electricity consumption and associated carbon emissions.
The benefits of installing a Powerstar variable voltage optimization system are:

  • Average savings in electricity consumption of 12%-15%
  • Capable of delivering greater savings than fixed voltage optimization systems
  • Supplies voltage at a constant level regardless of input instability, providing additional security
  • The set voltage can be changed at any time by site managers
  • Increases life expectancy of machinery and reduces electricity costs
  • Can significantly reduce harmonics
  • Guaranteed savings

Is Powerstar MAX right for my business?

The Powerstar MAX electronic-dynamic, variable voltage optimization system is 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 volatile or fluctuating voltage profile
  • The site has critical equipment on site that requires additional security
  • The site has high night loads as electricity is still consumed as other uses reduce demand
  • Powerstar MAX variable voltage optimization systems have provided significant savings for healthcare estates, hotel and leisure facilities, supermarket chains, data centers and cold storage sites.

If the Powerstar MAX variable voltage optimization system does not fit your requirements then have a look at our Powerstar or Powerstar HV MAX range.

What is variable voltage optimization?

Powerstar MAX variable voltage optimization systems maintain the voltage at a constant, stable level.

An example of this is visualized on the chart (right) with the voltage profile through a Powerstar MAX variable

voltage optimization system characterized through through the green line.

In many sites the voltage levels vary by as much as 30V per day, making fixed voltage optimization less suitable. Likewise those businesses who have critical services or equipment on site may benefit from the additional security of a constant, stable supply offered by variable voltage optimization.

Powerstar MAX variable voltage optimization systems do not supersede the Powerstar fixed voltage optimization range, they provide an alternative solution for businesses which are unsuited to fixed voltage optimization.

Product range specifications

Powerstar MAX variable voltage optimizationThe Powerstar MAX variable voltage optimization system is available in a range of sizes from 50kVA to 2,500kVA. Using intelligent electronic-dynamic technology it is capable of providing stable voltage to an accuracy of (± 1.5V).

Included in the Powerstar MAX  variable voltage optimization system is the HMI (Human Machine Interface), and automatic voltage reduction bypass. Additional options include harmonic mitigation winding and manual switch bypass.

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