Powerstar is the only voltage optimisation system in the world to be granted a patent on its design. The electronic Powerstar MAX is a dynamic voltage optimisation system that features advanced technology to automatically adjust the voltage output and maintain at the optimum level.

 Other benefits include:

• Over 95% of sites will achieve greater energy consumption savings than provided by simple double-wound voltage reduction transformers
• Record energy consumption savings of 26.1% have been achieved
• Average savings of 12% - 15% on energy consumption
• Provides a constant, stable voltage to maximise energy savings and increase protection to the building supply
• Capable of delivering greater savings than any fixed VO/VPO system on the market
• No moving parts, therefore no maintenance is required
• Reduction in maximum load demand (kVA) resulting in lower electricity bills
• The set voltage can be changed by site managers at any time
• Patented triple-wound system provides exceptional stability to protect against spikes and surges- eliminating harmonic distortions- thus providing added protection and improved power quality
• Voltage remains stable in the event that a site drops below 220V, which minimises the risk of equipment failures
• Intelligent interface to track product and site performance in real time
• Improved life expectancy of site equipment, therefore reduced maintenance costs
• Vertified savings, 100% guaranteed as per proposal

Most electrical equipment manufactured for Europe and the UK is rated at 220v and may indeed operate at an  even lower voltage.  One of the reasons Powerstar MAX is so effective is that the average voltage supplied from  the National Grid is 242V, whereas the nominal voltage is 230V. So in most cases you are being supplied more voltage than you need – and you’re paying for it,  whether you want it or not.

Powerstar MAX can optimise the voltage to bring it in line with the characteristics and loading of the site or through electronic-dynamic variable reduction, dependent on the demands of the site.  From our experience, for a 5% voltage reduction we expect at least 10% in energy savings. 

Powerstar MAX is a vital feature for sites with critical loads, secure data and important operations that require greater reliability and security.  Example sites include data centres, hospitals, hotels, cold storage, education facilities and retail outlets.
