The statutory supply band for Australia is 230V +10% to -6% or 216V-253V – this means that your voltage must be delivered between 216V and 253V, but on average it is delivered at 242V.

Electrical equipment manufactured for Australia is designed to work most efficiently at 220V – if voltage is supplied at a higher level than 220V, consumption will increase and maintenance on electrical equipment will increase.

Over voltage causes your electrical equipments lifespan to decrease – with motors suffering particularly bad when incorrect voltage is delivered.

Various technologies can be used to reduce voltage – but there is a need to do this efficiently so that the energy savings that result from correcting the voltage and not offset by energy wasted in the device itself.

The E-Four VPO optimises the voltage and simultaneously improves power quality for a whole site—this delivers a kWh and energy bill reduction. Uniquely, the E-Four VPO uses magnetic interaction to optimise voltage and improve power quality—no moving  parts or electronics are required.
