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.

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.

ECOsine™ Active is the new generation of active harmonic filters (AHF). It reliably mitigates harmonics and compensates voltage dips as well as reactive power.
ECOsine™ Active's functionality can be compared to waves in the ocean: If two waves of the same height and intensity meet, they cancel each other out. The same principle can be applied also to power networks. The AHF analyzes network disturbances and provides an opposing compensation current. In doing so, ECOsine™ Active actively adapts to fluctuations and responds in less than half a millisecond. Its compact dimensions, simple installation, and digital intelligence allow for a quick and staight forward integration in the most diverse applications.

Protection Filters are used on distribution networks which have a high THD (Total harmonic distortion), when the final target is to compensate the power factor at the fundamental frequency.
Its purpose is to avoid overloads due to harmonic currents in the capacitor, deflecting them to the network.
Protection filters are made with serial reactors and capacitors. The tuned frequency of each unit is adjusted between the fundamental and the lower harmonic present in the net, which usually is the 5 th order.
In this way, the filters present high inductive impedance for all the harmonic frequencies.

The usual practice for reactive energy correction in industrial electrical systems, consists in connecting capacitors, some times fixed or generally controlled using automatic power factor regulators. However, directly connecting capacitors to the system is not always possible for several reasons, such as:
The existence of harmonic currents, generated by non lineal loads.
The possibility of resonance between capacitors and certain inductive loads or even the reactive dispersion of the supply transformer.
Generation of microcuts or other disturbances in the voltage at the time of connecting the capacitors, if the system's short circuit power is insufficient.
Lessening high frequency command signals transmitted through the system.
It is necessary to add reactances for each of these cases, sometimes to filter disturbances or others to obtain an appropriate rejection of harmonics or high frequency signals and to meet international standards on these events.
CIRCUTOR has developed a complete manufacturing program for power filters to correct the following problems:
Correcting resonance problems
Harmonic rejection in certain parts of the installation
Absorption of harmonics to reduce THD in the installation

Metal Enclosed Harmonic Filter Banks should be considered when power factor correction is desired in a harmonic environment. The filter bank consists of an enclosure containing power factor correction capacitors connected in series with iron core harmonic compensated reactors. The resonant frequency of the filter equals that of the harmonic to be eliminated from the power system. The capacitors, reactors and auxiliary equipment are installed in the welded galvaneal enclosure and are shipped ready for interconnection. The reactors are typically tuned to the 4.7th (nominal 5th) harmonic to reduce the more severe 5th harmonic current in systems with large amounts of 6 and 12 pulse non-linear loads present. Equipments for filtering other harmonic frequencies are also available. Our engineering staff can help chose the design and harmonic tuning frequency that best fits your specific requirements, including automatic designs.

Three-phase and neutral line filters are a compact solution for the interference suppression on the mains input of cabinets and control units of equipment, ranging from industrial applications like machine tools to sensitive medical installations. These typically involve separate and often
insufficiently filtered frequency inverters and SMPS, causing current imbalance and significant interference problems. As individual elements they may be interference-suppressed already. The conjunction of several switching components in the same cabinet and a non-EMC conscious cabling will rise the demand for an additional EMC filter on the mains input of the whole installation. Many times this is the only way to get the CE mark for the cabinet in accordance with the EMC directive.
