What is Voltage Optimisation?

A Voltage Optimiser simply reduces the voltage applied to electrical equipment to make energy savings.

All electrical equipment intended for use in Europe must carry a CE mark to show it complies with the European Harmonised Voltages between 207-253V

How does Voltage Optimisation work?

How does Voltage Optimisation work?

VO works by reducing voltage from the UK average of 242 incoming volts to an acceptable operational 220 volts

Electricity that is not needed is returned to the grid, meaning you do not pay for the excess electricity, saving you money

Has no affect on the performance output of your electrical equipment and appliances as it is still operating within the 207-253V range
