Voltage optimisation reduces the supply voltage applied to an entire building, a specific area of a building, a lighting system or just a single piece of machinery. If the reduction in supply voltage is carefully matched to the needs of the connected electrical equipment it is possible to make a substantial energy saving.
The electrical supply voltage in the UK is between 235-245V, yet all electrical equipment across Europe is designed to operate between 220-230V to comply with current CE regulations. A large proportion of this equipment consumes more energy the higher the supply voltage applied to it.
Voltage optimisers intelligently monitor your incoming supply voltage and automatically reduce it to an optimum level to maximise energy saving. Whilst it is true to say that the higher the supply voltage the greater the potential for savings, your actual savings will depend on the type of electrical equipment used.
