Frequently Asked Questions
How does PhaseTec compare to transformer based power conditioners?
Compared to typical transformer based
power conditioners, PhaseTec's
digital power conditioner
wider input voltage range, tighter voltage regulation,
electronic power factor correction, provides better
protection for your equipment and offers many features
not available in any other power conditioner.
Most power conditioners are transformer
based equipment with differences in efficiency,
protection and the power quality they produce.
Transformers do not provide total isolation from adverse
power quality events. PhaseTec's
AC line conditioner uses double IGBT
conversion technology to convert
the incoming AC voltage to DC power, then back to AC. By completely reconstructing the AC wave form, it is
able to exert complete AC line conditioner control over power quality and
isolate your equipment from power problems.

voltage regulators are some sort of
transformer based power conditioner. Even if voltage
regulation is your only problem, PhaseTec's
line conditioner is a superior voltage stabilizer and
provides high efficiency and
unequaled protection for your equipment, all at a
UPS systems act as a power conditioner?
differences between UPS systems can be confusing. There
are a variety of types including standby, line
interactive, standby on-line hybrid, standby ferroresonant and double conversion on-line. In
general, double conversion on line systems provide the
best power conditioner Other types of systems may
provide varying degrees of power conditioning, or none
Are all double conversion systems the same?
double conversion systems are less reliable and less
efficient than others. When the incoming AC voltage is
converted to DC some systems step the DC voltage down to a
low value, usually to charge batteries. The DC to AC
inverter must step this voltage back up. This results in
lost efficiency and wear on components. PhaseTec's
conditioner does not
have batteries and has a high DC bus voltage resulting in
high efficiency and reliability.
Additionally, not all double conversion systems have
power factor correction on the input. If the
input power factor is not near unity (1.0), harmonics are
introduced into the input current that may cause power
quality problems for other equipment operating on the same
power source. Generators will also have to be oversized to
power a system that does not operate near unity. PhaseTec's
conditioner employs double IGBT conversion with electronic power factor
correction on the input module that results in a power
factor near unity with little distortion of the input
How do I know what kind of power conditioner
The need for
protection against adverse power events in general is poorly
understood. Many people have the mistaken impression that a
simple UPS and surge protector strips provide adequate
protection. Accurately diagnosing power quality problems
that are causing equipment malfunction can be difficult.
Many electric utilities have experts that can help you
diagnose your problems and offer solutions. Professional
power quality consultants may also be available.
simplest solution may be to get the most protection for
lowest cost. A PhaseTec
digital power conditioner with the optional isolation
transformer provides unequaled protection against everything
but a total loss of power, usually at a cost competitive
with even the most basic power conditioner solutions.
Should I buy a UPS system to get the power
conditioning I need?
initial cost of UPS systems has declined, they have become
more cost competitive with transformer based power
conditioners, leading to their increasing use as power
conditioners. The main function of a UPS is to supply
uninterrupted power to downstream equipment. It may or may
not provide adequate power conditioning, if at all. Power
outages are generally a rare occurrence, with the vast
majority of power disturbances comprised of other types of
events. If your application can afford to be down during
the occasional power outage, a good power conditioner can be
far more cost effective.
UPS generally has a higher initial cost and higher
maintenance than other power conditioning solutions. UPS
batteries are a significant up front cost and require
expensive maintenance. Certain on-line UPS will also have
low operating efficiency, resulting in high operating cost.
conditioner is essentially a high-end
UPS without batteries. PhaseTec's
conditioner is highly
efficient, reliable and requires no maintenance. And it
costs significantly less than most UPS and transformer based
Why does PhaseTec come with an
optional isolation transformer?
transformer provides a center tapped neutral for dual
voltage such as 240/120 volts. Most homes and facilities
require both voltages to operate a variety of electrical
equipment. The isolation transformer also has an
electrostatic shield to provide protection from common mode
noise in an electrical system.
