Energy Saving

Powersave-logo-tm-png-400px
Electrical equipment has to be designed to accept a range of input voltages about its nominal design centre, but if the actual supply is higher than necessary for proper operation, the equipment will consume more power than needed and also in many cases life is reduced - both increasing the cost of ownership.

Substantial savings in power consumption and improvements in operating life can thus be obtained by a reduction of the supply voltage.  Where the mains supply is stable, a fixed-ratio 'energy saving transformer', dropping the voltage by a suitable amount, typically 5-8%, is suitable.

However, where the mains supply is unstable, and particularly if the electricity supply company enforces its own 'energy saving' by voltage reduction, the result may be to reduce the equipment supply below acceptable operating limits.  This may be overcome by using a mains voltage stabiliser in 'energy saving mode' where the output is stabilised at a lower than nominal value, e.g. 220V on a 230V nominal supply.

PowerSave™ Voltage Optimisation is an innovative technology which helps companies slash their energy bills by up to 25%. It works by reducing the mains voltage to the level required by electrical equipment, which is often considerably lower than the standard 240V. This eliminates wasted power and provides organisations with a simple way of reducing carbon footprint and contributing towards their Carbon Reduction Commitments.

A division of UK-based Claude Lyons, the longest established company specialising in voltage control technologies, PowerSave™ Voltage Optimisation is backed by over 75 years of experience in the field of high quality power control solutions.

Energy Saving Stabilisers
The PowerSave™ 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.

PowerSave™ 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.

Applications

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)
