Energy-Efficient Harmonic Mitigating Transformers

Providing clean, energy-efficient electricity to power loads and are cost-efficient in the electrical distribution system. These transformers reduce harmonic content in electrical systems can result in a more reliable electrical system, lower maintenance costs, less downtime, fewer equipment malfunctions, and lower cooling system capacity. Components are available in a variety of phase-shift configurations that allow for flexibility to target specific families of harmonics.

General-Purpose Encapsulated Transformers

Typical transformer loads include lighting, heating, air conditioners, fans and machine tools. Loads are found in locations such as commercial, institutional and industrial structures. Applications are suitable for indoor and outdoor use and have an encapsulated design. Transformers are totally enclosed and a non-ventilated enclosure. (NEMA 3R rated)

Motor Drive Isolation Transformers

Drive Isolation drives are designed for use with AC/DC adjustable speed drives.

Mini-Power Centers

Type 3R enclosure is a main breaker, an encapsulated single-phase (Type EP) or three-phase (EPT) dry-type transformer, and secondary distribution load-center with main breaker.

Totally Enclosed Non-Ventilated Transformers

For special application for adverse atmospheric conditions it’s desirable to use a dry-type non-ventilated transformer vs. the ventilated standard unit which has openings in its enclosure to allow air to flow directly over the core coil.

Class I, Division 2, Groups C and D Transformers

Type EPZ and EPTZ are designed for installation procedures rated under 600V nominal operation.

  • Encapsulated design
  • Indoor and Outdoor use
  • Totally enclosed, non-ventilated enclosures

Open-Type Core and Coil Assembly Transformers

Typical transformer loads include lighting, heating, air conditioners, fans and machine tools. Loads are found in locations such as commercial, institutional and industrial structures.

Marine Duty Transformers

Typical transformer loads include lighting, heating, air conditioners, fans and machine tools. Loads are found in locations such as commercial, institutional and industrial structures.

  • Encapsulated design
  • Indoor and Outdoor use
  • Totally enclosed, non-ventilated enclosures

Buck-Boost and Low Voltage Lighting Transformers

Used to provide economical method of correcting a lower or higher voltage rating. This method is more suitable for efficient operation of electrical equipment. Type EP buck-boost transformers are small kVA single-phase transformers with dual primary and dual secondary windings, and are usually connected as autotransformers by using one unit for single-phase applications and 2 or 3 units banked for three-phase operation. These components are usually used for motor operation and are suited for low voltage lighting systems, such as outdoor lighting.

  • Encapsulated design
  • Indoor and Outdoor use
  • Totally enclosed, non-ventilated enclosures
  • NEMA 3R rated Enclosures

Medium Voltage Distribution Transformers

  • Ventilated, Standard NEMA 3R enclosure
  • Indoor or Outdoor application use
  • Upright mounting only 

Industrial Control Transformers

Transformers provide stepped-down voltages to machine tool control devices, enabling control circuits to be isolated from all power and lighting circuits. The control transformer line is adaptable for compact construction applications.

  • Type MTE
  • Type MTK
  • CE Marked
  • Type AP
