Industrial Control Transformers for
Harsh Environments
Designed for Control Panels where Internal
Installation of Control Transformers is prohibited.
Some specifications require installation of large control transformers, usually 1000
to 5000 VA outside the control cabinet. This means the transformer must be in a
sheet metal enclosure instead of the usual open core and coil construction method.
Acme meets this need by providing all of the power, protection, regulation and
performance of our standard industrial control transformers in one UL -3R enclosure.
These transformers are wound with copper magnet wire, deliver full nameplate
capacity, and provide the high regulation required in control applications.
Voltage combinations available are: 240 x 480V primary, 120V secondary and
240/480/600V primary, 120/100V secondary. Ratings available are 1000, 2000,
3000 and 5000 VA. All units are UL listed, CSA certified, and covered by Acme’s
exclusive 10-year limited warranty.
