-i Extremely high reliability

-i Wide range of variation network compensation

-i Stabilized voltage with high precision

-i Stabilization of high power use

The wider use of equipment with non linear absorption such as

rectifiers, speed variators, drives, switching power supplies, has

caused, besides traditional and well known voltage fluctuations, the

spreading of a new insidious type of electrical fault: harmonic

distortion.

This fault "deceives" traditional stabilising systems that, in its presence,

read wrong input voltage values. As a consequence a voltage is

delivered with an efficient value that differs from the rated one,

becoming greater as the harmonic distortion of the mains increases.

REG-M/REG-T/REG-Y stabilisers are Aunilec's technological and

innovative answer to this problem, permitting to supply electric users

with a voltage stabilised to the rated value they have been designed

for even in presence of strong harmonic distortions.

Power supply interferences

and failures

Failures on the distribution lines, atmospheric

discharges, continual 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 with the

electric energy producer.

Very often the tolerance is insufficient for more

sensitive facilities. Other times the mains

voltage reaches levels that exceed the

foreseen rated value by 15, 20 or even 25%.

The voltage fluctuations are particularly

treacherous interferences since they are not

seen and can only be detected by using

specific equipment. 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.

Voltage variations

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 "laserbeam mode", resulting in cutting

burrs or the shutting off of the beam.

•a transmitter gives signal distortion and its

components age more quickly.

•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.
