Safely transfer electricity among circuits with a control transformer. Also known as industrial transformers, these are essentially isolation transformers that provide good voltage regulation, as well as a high degree of secondary voltage stability in conditions characterized by occasional, brief periods of overload (AKA “inrush current”). Often used with lighting and heating systems, control transformers can also be used with various motors. 12v and 110v transformers, high voltage and industrial control transformers, Square D and power transformers are available.
