Control Power Transformers
Control Power Transformers
Acutran is designer and manufacturer of standard and custom control power transformers. We specialize in control power transformers that are single-phase and used to supply control power in switchgear, motor starters and distribution equipment. We also offer complete customization on you CPT design, with some of the standard features.
An Acutran control power transformer, or CPT for short, is an isolation transformer that is built to withstand short periods of inrush current while providing stable secondary voltage.
Transformers are manufactured in a variety of options to meet many applications. Control transformers are available in a variety of primary and secondary voltage combinations from 120/240, 240/480, 480/600, or any special combination.
CPTs are primarily used to supply voltage to a load. They require significantly more current when initially energized than under normal steady state operating conditions as in starter motor applications. Control Power Transformers are designed to reduce supply voltages to control circuits in switchgear. Or CPTs can be used by Original Equipment Manufacturers for their equipment to control voltage to secondary systems.
Acutran CPTs are designed and manufactured with the highest quality insulation, build using high quality grain-oriented core steel with copper conductors and all Acutran CPTs are VPI’d with UL approved varnish Acutran CPTs meet the requirements of IEEE C57.12.01.
We provide CPTs of all shapes and sizes – low or medium voltage, low run quantities with custom accessories like fuses, shields, or special terminal connections.
