Motor Auto Starters & Boosters
An auto transformer has only one(1) winding and therefore, is smaller and economical than conventional two(2) winding transformers; they can be used in banks on three-phase circuits or single phase to perform the same functions as transformers, with the exception of two(2) isolating circuits. Single unit Three-phase auto transformers are available as well.
REDUCED VOLTAGE AUTOSTARTERS
Auto transformers as motor starters are also available at 220 & 440V ratings. Voltage taps are standard at 50%, 65%, and 80%. Auto transformers with special voltages up to 4160V can be fabricated upon customer's request.
