The current industrial processes cohabit with multitude of loads that we could define as “difficult” – with high inductance character, high inrush currents (i.e.: motors), etc. - and furthermore they are very sensitive to the power supply fluctuations.
In those cases, the voltage stabilization should be carried out by means of the use of devices with enough robustness and with suitable overload capacity to make front to these loads without requiring an important power oversizing.
If to the above one we add a high output voltage accuracy (up to ± 1%), the result is the servomotors stabilizers EMi series of SALICRU, based on autotransformers of continuous regulation (ARC) and manufactured in a very wide range of power rates from 2 to 30 kVA in single phase structure and from 6 to 400 kVA in three phase (higher power rates under request).
Besides the three phase equipments can be manufactured in common regulation or independent phase regulation, which redounds in a better stabilization accuracy of the loads connected to each phase. Every equipment is controlled through a powerful microprocessor and monitored by a complete synoptic.
The current transformation industry uses the denominated machine-tool profusely, which most of the times, are highly sensitive to the voltage fluctuations: Milling machines, devastating machines, press machines, winch, polishers, electro-erosion machines and a long etc., they are in charge of giving shape to solid materials.
The switching and the electric manoeuvres, the numeric control, electric ovens or telecommunication transmission are other inherent applications to this type of equipment.

TDC series Features
This model represents the " top " of the range. Exactly thought in order to filter critical conditions generated from frequency converters, denotes attenuation values extremely elevates in the frequencies range from 150 to 600 KHz, normally most difficult to obtain. The highest levels of attenuation are obtained also maintaining the leakage current to extremely low values.

The REOTRON MEK 7711 provides a stabilised voltage within ± 6 % of nominal for a wide range of different supply voltages. It is possible to accommodate a variation on the supply of up to ± 25 %. The unit is delivered with plug-connectors fitted and is ready to operate with the equipment that requires a stable supply.
The output voltage is adjusted in 6 steps so that the input voltage range of 75% to 125% is stabilised to 94% to 106% of the effective 230V output. This is achieved by using an auto-transformer with a primary winding that has multi-tappings which correspond to different supply voltages. On the secondary side there are a further six tappings, which are connected to the output circuit through solid state switches (triacs). A microprocessor controller determines the appropriate tapping, depending to the input voltage level. In this way a constant output voltage is maintained.
Externally, a row of LED's are used to indicate whether the voltage is outside the allowable limits and which tapping has been selected. A soft-start prevents false tripping when the unit is powered-up.
Surge suppression is available as an optional extra.
