E4 Vs Transformer

Following the success of E-Four technology in Japan and the UK with several hundred thousand installations, there are now many companies selling auto-transformers as Voltage Power Optimisation.

The E-Four Corporation are the inventors of Voltage Power Optimisation, and E-Four is the only manufacturer of true Voltage Power Optimisation (VPO) - you should question the technology of anyone who claims to sell these products.

As in Japan and the UK, companies are claiming to sell VPO in Australia in order to capitalise on the current need for energy saving solutions. You should question why little information is available about how these units achieve the savings, where they are installed and how many are installed.

It is well documented that auto-transformers are the wrong technology for at-source voltage control as the sites entire electrical load is transferred through a unit which is prone to overheating.

Auto-transformers were not designed to be installed at source, which can be the most critical part of your electrical infrastructure. Incorrectly installed at source – auto-transformers have caused significant damage to sites in Japan, the UK and Australia.

Auto-transformers continue to be marketed across the globe as energy saving devices despite the obvious risks, which are routinely played down or “managed” through the inclusion of online temperature monitoring systems. 

No temperature monitoring is required for an E-Four VPO, which has been designed to sit at the most critical part of the electrical infrastructure and protect your site. 

With the success of E-Four VPO technology in Japan, other companies began marketing auto-transformers as energy-saving devices,  These ‘energy saving auto-transformers’ flooded the Japanese market, and after a spate of failures and fires Voltage Optimisation was given a bad name.

In Japan today, auto-transformers are no longer used for at-source Voltage Optimisation, while the E-Four VPO units continue to be installed by customers every year. The E-Four Voltage Power Optimiser is now recognized as the only safe means of at-source Voltage Optimisation.
