E-Four energy saving devices have been reducing energy consumption since 1993. This "true" VPO technology addresses the common problem of over voltage supply.  

 

Voltage Power Optimisation is unique technology only available in E-Four products. It is not the same as voltage reduction – the design is not based around conventional transformer technology – beware of imitations.

* Absolutely no maintenance. Absolutely ‘fit and forget’. Our unit has no moving parts - no fans, no thermal alarms, no monitoring systems and no oils.
