Variable Voltage Optimization Systems

What is Variable Voltage Optimization Technology…?

Powerstar MAX. The latest technology in Solid State, Electronic Controlled Voltage Optimisation Systems designed and built to provide your facility with Stable, Constant, Perfect Power Supply and Energy Security. Powerstar MAX maintains the voltage supply irrespective of the fluctuating input voltage supply from the grid.

An example of this is visualised on the chart (right) with the voltage profile through a Powerstar MAX Variable Voltage Optimisation System characterised through through the green line.

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

Powerstar MAX Variable oltage Optimisation Systems do not supersede the Powerstar fixed Voltage Optimisation Range, they provide an alternative solution for businesses which are unsuited to Fixed Voltage Otimisation.

What are the Benefits of a Powerstar MAX Variable Voltage Optimization System for my Facility…?

The Powerstar MAX range of Electronic-Dynamic, Variable 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 Variable Voltage Optimization System are:

• Average savings in electricity consumption of 12% – 15%

• Capable of delivering greater savings than fixed voltage optimisation 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

Is Powerstar MAX right for my business?

The Powerstar MAX electronic-dynamic, variable voltage optimisation 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 optimisation systems have provided significant savings for healthcare estates, hotel and leisure facilities, supermarket chains, data centres and cold storage sites.

If the Powerstar MAX Variable Voltage Optimisation System does not fit your requirements then have a look at our POWERSTAR or POWERSTAR HV MAX range.

All Powerstar Systems and Installations come with 15 Years Warranty and 100% Guaranteed Savings & ROI’s


The Powerstar MAX variable voltage optimisation 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.
