General Purpose Transformers
For over eighty-eight years, Acme Electric has been manufacturing Power Conditioning Equipment for use
in industrial, commercial and OEM applications. Built on a reputation for superior service, quality and
technical expertise in the transformer market, Acme is regarded as a true industry leader.
Dry Type General Purpose Transformers
Acme Electric is a full line manufacturer of low voltage (600V
and below) dry type distribution transformers using both copper
and aluminum conductor, offering an array of products between
0.05 -1000 KVA.
All Acme products are designed, constructed and rated to
meet or exceed the standards established by NEMA, ANSI and
IEEE. With few exceptions, all ACME transformers are
UL Listed.
K-Factor Transformers
Non-sinusoidal harmonic currents are created by much of
today’s electronic equipment. In fact, the switch mode power
supply found in desktop computers, data processors and other
office equipment is a major source of harmonic currents. Other
sources include electronic ballasts, variable frequency drives,
heating controls and rectifier circuits.
These non-linear loads can cause the transformer’s neutral
conductor to overheat, requiring special transformer design.
Acme’s non-linear load isolation transformers use special
winding techniques to minimize the eddy current losses
generated by harmonic currents. A double-sized neutral
conductor handles the excessive neutral current found in
non-linear load applications, preventing the transformer
from overheating.
Harmonic Mitigating Transformers
Harmonic currents can sometimes cause equipment to
malfunction, motors to burn out, circuit breakers to trip, and
fuses to blow. In such a case, there is an advantage to specifying
a transformer that treats the harmonic anomalies versus simply
tolerating them. Acme’s Harmonic Mitigating Transformers offer
the best solution for combating harmonics associated with non-
linear loads.
These foil wound transformers will, by nature, be smaller, more
efficient, and have lower eddy current losses than their wire
wound counterparts. Acme’s Harmonic Mitigating Transformers
utilize a time proven zig-zag connection in the secondary circuit
that results in a phase shift of the triplen harmonics and causes
them to cancel one another. This technology not only results in
cooler operation and “cleaner power”, but also provides a more
energy efficient means of dealing with harmonic problems.
CSL-3 / NEMA Premium Transformers
The Acme POWERWISE C3 sets a new standard for
efficiency and reliability. Due to the use of more efficient core
material and higher-grade electrical steel, POWERWISE C3
transformers are the most efficient commercially available
transformers. With a 30% increase in efficiency performance
over standard TP-1 transformers, these energy-efficient units
exceed the requirements of the US Department of Energy
Candidate Standard Level (CSL) 3 performance standard.
POWERWISE C3 transformers achieve the lowest life cycle
costs by reducing annual energy costs. Depending on the size
of the transformer, this can mean thousands of dollars saved
per transformer. And, because they generate lower losses, they
reduce power drawn from generating stations, resulting in lower
greenhouse gas emissions and less smog.
Acme POWERWISE C3 transformers are copper wound,
3-phase common-core, dry-type ventilated isolation
transformers. Each transformer is meticulously constructed
to ANSI/IEEE Standards and is UL and CSA listed. The
POWERWISE C3 transformer is a perfect choice for K
through 12, college, university, healthcare, governmental and
commercial buildings where the total life cycle cost of the
facility and its electrical system is a priority.
