Energy saving mains voltage regulators

20 February 2008 Power Electronics / Power Management

Denver Technical Products in conjunction with Claude Lyons of the UK, is offering energy saving regulators aimed at alleviating the electricity crisis in South Africa.

Electrical equipment is designed to accept a wide range of input voltages about its nominal design centre. However, if the actual supply is higher than necessary the equipment will consume more power than needed and in many cases, equipment life is reduced, effectively increasing the cost of ownership. A 230 V linear appliance operated at 240 V will consume approximately 9% more energy than necessary.

A voltage reduction within statutory limits, of up to 12,5%, can produce up to 25% reduction (subject to loads) in energy consumption and in addition will extend the life of many types of electrical apparatus.

Power Save regulators have obvious advantages over fixed ratio transformers, by providing additional energy savings through greater voltage reduction and more importantly, phase voltage balance and regulated output voltages. They are available in single-phase 7 kVA to 480 kVA and three-phase up to 2000 kVA.
