The dwindling fossil fuel reserves, the need to reduce carbon dioxide emissions and lower availability of financial resources has spurred energy production from renewable sources and strongly boosted the development of technology for optimising (limiting) electricity consumption.
Ecostab automatic voltage optimisers are one of the solutions offered by new technologies to users.
These devices comply with the requirements of IEC 60038 for electric equipment operating tolerances and supply an operating voltage which minimises consumption without impairing performance or reducing reliability.
Ecostab automatic voltage optimisers deliver a stabilised voltage which can be set to the minimum tolerance established in IEC 60038, i.e. -10% (207V). This value is guaranteed also in presence of significant mains voltage variations. Interestingly, these devices are also excellent mains voltage stabilisers.
• Standard single-phase models can deliver a variable voltage from 230 to 207 V with input voltage comprised in the 207-253V range.
• Standard three-phase models can deliver a variable voltage from 360/207 to 400/230 V with input voltage comprised between 360/207 V and 440/253 V.
Models capable of broader input voltage variations may be built on demand. These may be needed because voltage may sometimes exceed the 10% tolerance specified in the supply contract.
Automatic voltage stabilisation is a key function that sets ECOSTAB voltage optimisers apart from simple autotransformers, which also reduce voltage but cannot guarantee certain savings due to the continuous voltage variations of the mains.
