Control Transformers
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 come in open, molded and general purpose enclosed styles.
Control Transformers
Designed for industrial panels, motor control, and automation systems, HPS control transformers are built to keep your systems running safely and efficiently. These units come in open, molded and enclosed styles.
Drive Isolation Transformers
HPS Drive Isolation Transformers (DIT’s) are mandated to meet NRCan 2019 efficiency standards in Canada, but are exempt in the U.S. from DOE 2016 efficiency standards.
Drive Isolation Transformers – NRCan 2019 Efficiency
Compliant to the latest NRCan efficiency standards. Meets the demands of both AC and DC variable speed drives while providing the required voltage change.
Drive Isolation Transformers – Low Efficiency
Designed to meet the rugged demands of both AC and DC variable speed drives and provide the required voltage change.
Reactors & Filters
HPS offers line reactors that can significantly enhance the performance, life expectancy and efficiency of both the motor and the drive.
SineWave Filters
Condition the pulse width modulated (PWM) output of a variable frequency drive (VFD) into a nearly perfect sinusoidal waveform
Reactors
Offers improved performance and reliability that delivers protection for your motors and drives.
dV/dT Filters
Minimizes the damaging peak voltages that occur along the motor cables and within the motor windings.
dV/dT Filters – Legacy
Offers improved performance and reliability to protect your motors and drives.
Motor Starting Autotransformers
Motor Starting Autotransformers are combined with other controls to produce a reduce voltage starter.
Motor Starting Autotransformers
