Energy-saving regulators

March 2008 Electrical Power & Protection

Denver Technical Products in conjunction with Claude Lyons of the UK, now offer energy-saving regulators, which are topical products at the moment, in view of 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% (subject to load) reduction in energy consumption and in addition will extend the life of many types of electrical apparatus.

The reduction of the supply voltage to a controlled level, allows equipment to operate at optimum efficiency, thus lowering power consumption and overall running costs.

The Power Save has advantages over fixed ratio transformers, by providing additional energy savings through greater voltage reduction and more importantly, phase voltage balance and regulated output voltages. Increasing demand is expected to affect the stability of the supply and price increases are forecast. Both factors will make Power Save a solution that accommodates future deterioration by ensuring a safe and regulated supply, achieving savings and reduced carbon emissions from power stations.
