We reduce your electricity bill, extend the service
life of your electric and electronic equipment and limit
repair and maintenance costs.
The power company has to feed extra voltage to the grid to guarantee that
electricity is provided satisfactorily to all users. The incoming voltage can go up
to more than 250 Volt, while you often only need 215 Volt. You still have to
pay for the extra voltage. What’s more, your electrical equipment is loaded
unnecessarily, which reduces the service life and increases the costs of mainte-
nance and repair.
UST manufactures a full line of industrial-grade power conditioners - electronic
voltage regulators (EVR) with patented microprocessor-controlled tap switch-
ing technology - that offer far more reliable power protection and energy
saving.
When you place a UST power conditioner between the grid and your critical
equipment, you can be assured that common electrical anomalies, of any
intensity or duration, will be stopped and corrected within, depending on
your needs, one, two or three cycles and an efficiency of 99%.
At an incomming voltage of 230V +/- 10%, the nominal output voltage can be
set to 215V +/- 1%.
The UST power conditioners com-
bine the best qualities of typical
mechanical and electronic voltage
regulators while eliminating their
weaknesses.
Mechanical voltage regulators are
valued for their high overload
capacity and good voltage regula-
tion, but these qualities are offset by
their slow correction speed and the
need for regular maintenance of
moving parts. Similarly, electronic
voltage regulators are known for
their fast correction speed, but
suffer from poor overload capacity.
The UST power conditioners provide
high overload capacity for loads
with large inrush-current require-
ments. At the same time, it provides
consistent voltage regulation and
fast correction without regular
maintenance or moving parts.
Within the last decade, UST power
conditioners have proven capable of
reliably and efficiently compensating
for variations in incoming voltage.
UST power conditioners minimize
and balance variations in voltage to
protect equipment, ensuring consis-
tent voltage and saving money.
Non-linear consumers frequently
lead to serious problems with regard
to power quality. Therefore, it makes
sense to measure consumption levels
and loads together with the general
power data in the stores, collect the
data and benchmark the stores with
each other.
Many loads in commercial facilities
have inductive or mixed characteris-
tics, such as: refrigeration systems
and air conditioners. These types of
electric devices include either a
single phase or three phase induc-
tive motor.
When inductive motors work at
nominal power level they are very
efficient (typically >90%); however,
in many cases these motors are
oversized and are actually operated
under partial load conditions. In this
regime the inductive motor is
inefficient, since the power factor is
low and the working current is high
- as a result, the motor produces
more internal and network losses
and emits more heat.
For motors running at loads below
the nominal, voltage reduction in
the allowed range will change the
motor working point and bring the
motor to a more efficient position in
the Load vs. Efficiency curve.
A similar improvement can also be
detected at the power factor.
Increase of the power factor will
actually reduce the working currents
and reduce conduction losses in the
facility electric network.
Stable output voltage (215V +/- 1%). Fast response time of up to 20 ms (no risk of undervoltage) and an efficiency of 99%.

We Save Power performs energy
audits including all aspects of power
quality and EMC.
Based on measurements, we can
translate our knowledge and under-
standing of electrical installations,
electrical equipment and electronics,
motor- and drive-technology into a
clear reporting about the ‘health’ of
your power supply, including advice
for any necessary improvement.
Neither power control and power
quality protection, nor the lack of it,
are without cost. An important part
of assessing power quality related
costs is determining what specifically
is being affected and where, or in
what aspects of business operations,
these costs show up. The benefits of
good power control and power
quality vary from energy savings up
to damage protection. Prevention is
relatively cheap ranging from simple
good practice to the installation of
support equipment.
