ACME TRANSFORMER TYPES
AC Line Reactors
Acme Line Reactors prevent equipment failure and costly downtime.
They protect your sensitive equipment from harmful line disturbances
and add years to your equipment.
AC Refrigeration & Appliance
Transformers
The transformers in this section are autotransformers
designed to change a wide range of voltages to the standard
motor voltages for domestic appliances, air conditioners
and related equipment.
Transformer Accessories
Acme offers a wide array of accessories for your transformers such
as
lug kits, space parts, standard taps, thermal switch kits, wall
mounting brackets and weather shields.
Buck-Boost Transformers
These
transformers provide
tremendous capabilities and flexibility in KVA sizes and
input/output voltage combinations. Basically, you get 75 different
transformers... all in one convenient package.
DC Power Supplies
Acme, with its new line of DR series, offers you an
innovative solution for many of your control applications.
Acme DC power supplies provide you with optimal performance with the
least impact on installation time and space.
Drive Isolation Transformers
The Acme Drive Isolation Transformers are
specifically designed to accommodate the
special voltages and KVA sizes unique to AC
and DC motor drive applications.

Selecting an Acme
Industrial Control Transformer
Five easy step
selection process:
1. Determine the voltage and frequency of the
supply circuit: Example: 460 Volts, 60 Hz.
2. Determine the total inrush VA of the
control circuits from the manufacturer’s
data or the contactor data table. Do not
neglect the current requirements of indicating lights and timing
devices that do not have an inrush VA but are energized at the same
time as the other components in the circuit. Their total VA should
be added to the total inrush VA.
3. Refer to the regulation data chart. If the
supply circuit voltage (Step 1)
is reasonably stable and fluctuates no more than 5%, refer to the
90% Secondary Voltage column. If it fluctuates as much as 10%, refer
to the 95% Secondary Voltage column. Go down the column you have
selected
until you arrive at the inrush VA closest to, but not less than, the
inrush VA of your control circuit.
4. Read to the far left side of the chart, and you have selected the
continuous nominal VA rating of the transformer needed. The
secondary voltage that will be delivered under inrush conditions
will be either 85%, 90%, or 95% of the rated secondary voltage —
depending on the column selected from the regulation data chart. The
total sealed VA of the control circuit must not exceed the nominal
VA rating of the transformer selected from the manufacturer’s data
or the contactor’s data table.
