Cutting Energy Costs by up to 20% and ensuring we all do our bit for the environment. An Ashley-Edison VOLTSTREAM Automatic Voltage Optimiser (AVO) reduces your energy usage by optimising the electricity supply voltage significantly reducing your ongoing electricity costs and, through the need for less energy, greatly assists in the quest for reducing your carbon footprint.
Cutting Energy Costs by up to 20% and ensuring we all do our bit for the environment.
An Ashley-Edison VOLTSTREAM Automatic Voltage Optimiser (AVO) reduces your energy usage by optimising the electricity supply voltage significantly reducing your ongoing electricity costs and, through the need for less energy, greatly assists in the quest for reducing your carbon footprint.
In addition, a VOLTSTREAM AVO protects electrical equipment against damaging power surges and voltage transients. Through ensuring an optimised supply voltage, your electrical load equipment should be able to operate more efficiently and be more able of obtaining intended design life – with the added benefit of reduced ongoing equipment maintenance costs.
