EST transformers

 Energy Saving Transformers

The powersave â„¢ Energy Saving Transformer (EST) is a tapped auto-transformer which reduces voltage by up to 12%. This proportional reduction provides an effective way of prolonging the life of electrical equipment, reducing costs and cutting carbon emissions for sites with a reasonably stable mains supply.

At full load the powersave â„¢ EST Voltage Optimisation delivers efficiency of more than 99.5%. Many types of electrical equipment work perfectly well on a lower voltage than the standard mains supply, and indeed the performance of some equipment is actually optimised when the voltage is reduced. The EST can realise energy savings of up to 20% and help organisations meet their Carbon Reduction Commitments.

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)
