Dynamic voltage optimisation

Energy Saving Stabilisers

The powersave â„¢ Energy Saving Regulator (ESS) is proven to achieve greater energy savings than any other available approach. It reduces supply voltage to a controlled, site-adjustable level to ensure your equipment is operating on the optimum voltage and not consuming excess power, delivering energy savings of up to 25%. And as each kWh of electrical energy saved is equivalent to 0.43kg of CO2, it also helps organisations reduce their carbon footprint and meet their Carbon Reduction Commitments.

powersaveâ„¢ ESS Voltage Optimisation technology provides energy savings over and above fixed ratio transformers through greater voltage reduction. It is able to maintain a regulated output even during power dips, so it’s ideal for locations where mains supply quality fluctuates.  The stabilised voltage supply can be set at the optimum level for the equipment it powers, and it will stay at that value as the incoming voltage varies.  By ensuring that electrical equipment isn’t consuming more power than necessary, the ESS not only reduces overall energy bills - it also prolongs the life of equipment.

UK Established Since 1918

The Claude Lyons Group was founded in the UK in 1918 and is still in private ownership. Since our early days we have been innovators in areas related to voltage and power control and more recently in energy saving and harmonic mitigation. Operating as a global exporter with many years experience we can justifiably call ourselves a world leader in the field of voltage stabilisers, power conditioning and uninterruptible power supplies (UPS)
