-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.
