Fiche technique Aunilec Regulateur REG EN - 1

REG stabilisers are particularly suitable for applications that require: • high reliability. For example they can be installed in areas with difficult access, subject to critical environmental conditions due to cold, high temperatures, humidity, atmospheric discharges; • capability to compensate wide mains voltage variations. This is a typical requirement of equipment installed in areas that are far from the distribution transformer substation and in fast developing countries. • high precision of the stabilised voltage. Ideal condition for calibration and inspection stands, electric furnaces, professional lighting equipment: • stabilisation of high power users or with high inrush currents like e.g. motors, air conditioners, compressors, pumps; • simple and limited maintenance. Very important feature where it is difficult to find qualified personnel for servicing; • wide range of models. According to the ambient conditions, the stabilisers can be supplied in enclosures with protection degree IP00, IP2I, IP54 INDOOR, IP54 OUTDOOR. Automatic voltage stabilisers - REG Series Automatic voltage stabilisers - REG The electric energy producers generate a correct voltage. However, failures on the distribution lines, atmospheric discharges, continuous load variations and disturbances generated by the users make it impossible to guarantee always a steady voltage within the tolerance bandwidth stipulated in the supply contract. Very often this tolerance is insufficient for more sensitive equipment. Other times the mains voltage reaches levels that exceed the foreseen rated value by 15, 20 or even 30%. Power supply and professional users The voltage fluctuations are particularly treacherous interferences since they are not seen and can only be detected by using specific instrumentation. When such interferences are present, the electrical equipment seems to maintain correct operation but disguises serious problems that at times are beyond repair. Even an ordinary light bulb, if overpowered by 10%, continues to give light, but halves its operating life; if underpowered by the same percentage it loses 30% of its brightness. The situation becomes much more serious in the case of voltage variations on more complicated equipment: • a computer may become damaged or make unexpected errors: • a laser cutting machine undergoes changes in the "laser beam mode", resulting in cutting burrs or the shutting off of the beam; • an electric drive causes undesired changes in the speed of the powered motor and damage to the data storage and power terminals; • an "electromedical" device gives incorrect results, wastes expensive reagents and loses the samples to be analysed. proposal The REG stabilisers are registered names of two series of electrodynamic voltage stabilisers that offer a reliable and tested economic solution to inconveniences caused by voltage fluctuations. Their use is a real investment because the elimination of the inconveniences means a reduction in costs and an increase in productivity. Very often it is only necessary to avoid a few minutes machine downtime or just one failure to repay the cost of the stabilisers.

Automatic voltage stabilisers - REG Series Automatic stabilisers Operating principle A motorised variable transformer supplies a series transformer the voltage -in phase or phase opposition- necessary to bring the mains to the rated value. The three-phase models are available in two versions: REG-T models, which regulate on the average of the three phases and are suitable for balanced lines and a maximum load unbalance between the phases up to 50%: REG-Y models that, having three separate control circuits, individually regulate each phase and ensure a high precision both in case of an...

Automatic voltage stabilisers - REG Series Automatic stabilisers Cooling natural air convection This is the distinctive characteristic of all models with protection degree IP2I; it dramatically increases the reliability as the cooling of the magnetic components and the electronic control boards is ensured by natural convection without fans. Fans and the relevant filters must be constantly checked, cleaned and periodically replaced. Moreover, the absence of fans avoids sucking of dust which would deposit on the copper tracks reducing the contact surface between the electro-graphite rolls and...

Automatic voltage stabilisers - REG Series Square section linear variable transformer The linear variable transformers are the heart of Aunilec REG series voltage regulators. They are the most extraordinary, particularly sophisticated to manufacture and technically worked out component. As a matter of fact the mobile contact ensuring the stabilisation is flown by currents of some tens of Ampere. The square section winding is characterised by a much higher "filling factor" than the typical round section winding. The pictures show in both types of winding the large difference in surface...

Automatic voltage stabilisers - REG Series Warranty Extended warranty to 5 years. Reliability The criteria used to dimension the electrical and electronical parts guarantees greatest reliability. The declared performance always consider the worst conditions simultaneously: nominal power with minimum input voltage of the mains and maximum ambient temperature for unlimited time. Automatic stabilisers Natural convection The cooling is obtained in the IP21 models by natural convection into the air only. The total absence of fans (Fan-Free) increases the reliability of the product enormously and...
