Invented in 1993 by Japanese Scientist Kunio Shimazu of E-Four Corporation, he designed the technology from a blank canvas, with the sole purpose of reducing energy consumption by correcting over voltage and addressing a common number of power supply problems.

Unique to an E-Four Voltage Power Optimiser, the savings and improvements in power quality are achieved the through the internal interaction of magnetic fields meaning that moving parts or electronics are not required.

Voltage Power Optimisation is a unique technology only available in the E-Four Voltage Power Optimiser, it’s not the same as voltage reduction – the design is not based around conventional transformer technology – beware of imitations.

* Absolutely no maintenance and ‘fit and forget’ means that the unit has no moving parts - including any fans, thermal alarms or monitoring systems
