HPS Sentinel G ventilated stand-up distribution transformers meet the latest energy efficiency standards as outlined by DOE and NRCan. These transformers offer significant energy savings and environmental benefits.
Dry-type encapsulated 3-phase distribution transformers from Acme Electric offer a UL listed, CSA certified and UL type 3R enclosure, which meets or exceeds all listing criteria including NEMA, ANSI and OSHA standards. Models over 9kVA offer an extra-large front access wiring compartment; 15kVA models offer top access for easier installation and cooler case temperatures. Completely enclosed style makes this series suitable for indoor/outdoor service.
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:
Hammond HPS Spartan® industrial open core and coil control transformers offer an efficient and economical solution for applications where high inrush or machine tool duty are not necessary. The units are well suited for HVAC applications, signal and alarm systems, motor control circuits, lighting and circuit isolation. Four series of open core control transformers are available:
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:
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:
