HPS Control Transformers are Isolation Transformers designed to provide a high degree of secondary voltage stability (regulation) during a brief period of overload condition (also referred to as “inrush current”). These units are also known as Machine Tool Transformers, Industrial Control Transformers or Control Power Transformers.

HPS also offers Drive Isolation Transformers (DIT's) to meet the rugged demands of both AC and DC variable speed drives and also provide the required voltage change.  DIT's are mandated to meet NRCan 2019 efficiency standards in Canada, but are exempt in the U.S. from DOE 2016 efficiency standards.

In addition, HPS offers line reactors that can significantly enhance the performance, life expectancy and efficiency of both the motor and the drive.

Motor Starting Autotransformers are combined with other controls to produce a reduce voltage starter.
