The HPS Imperator series of machine tool industrial control transformers are specifically designed to meet the high inrush industrial applications where electromagnetic components such as relays, solenoids, etc. are used. The HPS Imperator design, utilizing superior insulation systems and being constructed with high quality silicon steel laminations for optimum performance, will meet or exceed UL and CE standards. Backed by an industry leading LIFETIME warranty, the HPS Imperator industrial control transformer line offers superior performance, quality and value.
Note from Hammond Power Solutions: "At HPS, we rate the VA capacity of our transformers at the output... where it counts. Other transformer manufacturers rate their capacity on the input side of the transformer, which can result in a 5% to 20% lower actual VA at the output."

HPS Reactors are designed to address line-side issues associated with variable frequency drives. They mitigate voltage and current transients that can cause nuisance tripping of a drive. Reactors also minimize harmonic current levels within the drive supply circuit. When used on the output side of IGBT-based, PWM-type AC drives, HPS reactors reduce the motor operating temperature and audible noise by moderating line transients seen by the motor. Using HPS line reactors enhances the overall performance, life expectancy, and efficiency of the motor.

• Enclosures are rugged, steel construction with UL50 ANSI 61 Grey Paint
• NEMA 3R Enclosures Available Upon Request
• Includes Finger-proof Terminal Blocks or Terminal Pads

Buck-boost transformers offer an economical solution to the adjustment of line voltages that are slightly above or below normal. When a buck-boost transformer is connected as an autotransformer, only a portion of the load kVA is actually transformed. The majority of the load kVA is passed directly through to the source. For this reason a buck-boost transformer may be used to supply a much larger kVA load than is indicated on the nameplate.
Buck-boost transformers can be used to adjust stable voltages only.

• Ratings From 7.5 to 660 kVA
• 60 Hz Frequency
• Primary Voltage: 208D, 230D, 460D, 480D, 575D

Standard Drive Isolation Transformers, are designed to meet the rugged demands of both AC and DC variable speed drives and also provide the requried voltage change. The separate primary and secondary windings provide electrical isolation between the incoming line and the SCR load. The windings are designed to withstand overcurrent of 150% of the rated load for 60 seconds or 200% of the rated load for 30 seconds.
Drive Isolation Transformers are sized to match standard motor horsepower and voltage ratings. Standard sizes range from 5 to 600 HP in six standard voltages.

HPS Sentinel G general purpose distribution transformers are rated for 600 volts and below. They are generally used for supplying appliance, lighting, heating, motorized machine and power loads from electrical distribution systems.
For applications involving non-linear loads, please use our HPS Sentinel K product line.

By using a RM series line reactor many line problems can be eliminated. Additionally, performance, life expectancy and efficiency of both the motor and the drive itself are significantly enhanced. Due to the care in the selection of core material with its optimum flux density, RM line reactors will not saturate under the most adverse line conditions.
