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.

The UST Electronic Voltage Regulators feature:

Fast voltage regulation corrects under/over voltage, sags, and swells

High fault-clearing capacity permits reliable operation of other

protective devices

Built-in surge suppression for surges and spikes

Line isolation minimizes transients

Transformer shielding reduces line noise to deliver clean power

Independent phase regulation to correct voltage imbalance

Input circuit breaker protects against damaging over-current and

short circuits

Automatic failsafe electronic bypass keeps the load powered
