HPS Imperator Encapsulated Core Control Transformers

1-Phase Encapsulated Core Industrial Control Transformers

HPS Imperator® control power transformers from Hammond are specifically designed for high inrush applications requiring reliable output voltage stability. Designed to meet industrial applications where electromagnetic devices such as relays, solenoids, etc. are used, these industrial power transformers maximize inrush capability and output voltage regulation when electromagnetic devices are initially energized. Encapsulated coils protect the transformer from moisture, dirt and other industrial airborne contaminants. Four series of encapsulated control transformers are available:

MQMJ Series - 240x480 VAC to 120x240 VAC
MGJ Series - 208x277x380 VAC to 120x240 VAC
PG Series - 120x240 VAC to 12x24 VAC
MLI Series - 480x240 VAC to 25x120 VAC

HPS Fortress Encapsulated Transformers

HPS Fortress™ encapsulated transformers provide an innovative design that is ideal for commercial applications where quality, ease of installation, and low cost are key. All Fortress units are encapsulated power transformers with electrical grade silica sand and resin compounds, which completely enclose the core and coil to seal out moisture, airborne contaminants and eliminate corrosion and deterioration. This type of power transformer is also sometimes referred to as a potted transformer. 480V transformers and 60Hz transformers are among the most popular models offered. Three series of encapsulated transformers are available:

C1F***LE Series (240x480 to 120x240 VAC)
C1F***WE Series (120/208/240/277 VAC to 120x240 VAC)
C1F***XE Series (220/208/200/190x440/416/400/380 to 240x120 VAC)

HPS Fortress Encapsulated Transformers are priced from

Jefferson Electric Buck-Boost Transformers

Buck-boost transformers are designed to maximize the performance and life of electrical equipment. They are typically used to power loads with specific voltage requirements that differ from the available line voltage. Buck-boost transformers can be connected as auto-transformers or isolation transformers. As an auto-transformer, these buck-boost transformers provide a means of raising (boosting) or lowering (bucking) a supply line voltage by a small amount (usually no more than 20 percent). When connected as an isolation transformer, these transformers can be used to step-down supply power to low voltage circuits at the nameplate rating listed. Two ranges of buck-boost transformers are available:
