Fiche technique Aunilec Economiseurs EcoREG EN - 1

Automatic voltage optimisers EcoREG series Automatic voltage optimisers Automatic voltage stabilisation is a key function that sets EcosREG voltage optimisers apart from simple autotransformers, which also reduce voltage but cannot guarantee certain savings due to the continuous voltage variations of the mains, in order to prevent the delivered voltage from dropping excessively low as a consequence of mains fluctuations, autotransformers can never provide maximum savings. Power supply and professional users A common misconception about VO is that a reduction in voltage will result in an increase in current and therefore power consumed will remain constant. This is true for certain fixed-power loads, however most sites have a diversity of loads that will benefit to a greater or lesser extent with energy savings aggregating across a site as a whole. The benefit to typical equipment at three phase sites is discussed next page.

Onduleurs • Redresseurs • Batteries Onduleurs • Redresseurs • Batteries Automatic voltage optimisers EcoREG series Voltage optimisers THREE PHASE AC MOTORS: The three phase induction motor is one of the most common types of three phase loads and is used in many items of equipment including refrigeration, pumps, compressors, fans, air conditioning, conveyor drives and lifting systems. Overvoltage results in flux saturation of the iron core, wasting energy through eddy currents. Increased hysteresis losses. The drawing of excessive current results in excess heat output from copper losses. The...

Automatic voltage optimisers EcoREG series Voltage optimisers proposal Voltage optimisation is a term given to the systematic controlled reduction in the voltages received by an energy consumer to reduce energy use, power demand and reactive power demand. While some voltage "optimisation” devices have a fixed voltage adjustment, others electronically regulate the voltage automatically. Voltage optimisation systems are typically installed in series with the mains electrical supply to a building, allowing all its electrical equipment to benefit from an optimised supply. Overvoltage leads to...

Saving and return on investment There are many factors which contribute to saving energy and reduce the payback period: a.Mains voltage which is not always close to rated value. Voltage is usually higher late at night: 10% higher than the rated value is a common condition. This level is often exceeded when the user is located near an electric substation. Saving increases to approximately 20% when the voltage exceeds 10% of the rated value. b.Type of powered device. Some devices allow higher saving than others and some electric devices do not provide any significant saving at all. Voltage...

Automatic voltage optimisers EcoREG series HIGHLIGHTS Voltage optimisers 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. EcoREG 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...

Automatic voltage optimisers EcoREG series 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 EcoREG voltage optimisers apart from simple autotransformers, which also reduce voltage but cannot guarantee certain savings due to the continuous voltage variations of the mains. In order to prevent the delivered voltage from dropping excessively low as a consequence of mains fluctuations, autotransformers...

Voltage optimisers Automatic voltage optimisers EcoREG seriesOperating principle An electronic control circuit detects the voltage delivered by the voltage optimiser and compares it to a reference voltage. If the difference between the output voltage and the reference voltage exceeds the preset tolerance limits, an error signal is generated; this signal may be either negative or positive according to whether the output voltage is lower or higher than the preset value. This signal activates the servomotor which moves the mobile contacts (electrographite rollers / brushes) of the variable...
