UK mains voltage is, on average, 242 volts, but most electrical equipment is designed to operate most effectively at 220 volts.
Voltage optimisation (VO) systems work by reduce the incoming mains voltage to an optimum level, resulting in reduced energy consumption, as well as protecting electrical machinery and equipment.
VO generally offers a good return on investment, and can be applied to many sectors including manufacturing and industrial sites, education facilities, offices, retail outlets and leisure facilities.
