The Energy Policy Act of 2005 (H.R. 6) requires Distribution Transformers manufactured after January 1, 2007 to meet specific energy efficiency requirements. EPAct 2005 defines the term "distribution transformers" as any transformer which:

• Has an input voltage of 34.5 kV or less
• Has an output voltage of 600 V or less
• Is rated for operation at a frequency of 60 Hz
• Has a capacity of 10 kVA to 2500 kVA for liquid-immersed units and 15 kVA to 2500 kVA for dry-type units

Hevi-Duty encapsulated transformers are rated for Hazardous Locations (Class 1, Division 2, Group A-D) as well as harsh industrial environments. Encapsulation and rugged NEMA 3R enclosures protect the transformer from dust, moisture, and provide extra shock and vibration resistance. Hevi-Duty UL listed transformers fully comply with the latest addition of the National Electrical Code for Class 1, Division 2, Group A-D locations when installed in compliance with NEC 501-2(b).

The SBE series (encapsulated and open style) Sola transformer is available from 50 - 5000 VA, 55°C Rise and features copper windings and encapsulation (through 1000 VA) for longer life and protection from the environment.

Sola Hevi-Duty's low temperature rise transformers feature a 220°C insulation system and temperature rise of only 80°C or 115°C under full nameplate load. The result is 13-21% lower operating losses than conventional 150°C rise units.

• Shielded for quality power
• UL-3R outdoor enclosure with optional weather shield
• Thermal reserve allows for continuous overload operation at 150°C rise
• Aluminum windings for greater insulation life
• Class 220°C insulation system, 115°C or 80°C rise
• Single and three phase availability

Sola/Hevi-Duty buck-boost transformers are designed to supply power to low voltage lighting circuits, control panels or other systems requiring 12, 16, 24, 32, or 48 Volts. When connected as an insulating transformer, the transformer's capacity matches the nameplate KVA rating. Sola Hevi-Duty buck-boost transformers are also suited for low voltage landscape lighting. They are UL listed for outdoor service and their compact size makes them the perfect solution for providing power to accent lighting applications. When using dimmers for low voltage applications, use only dimmers designed and rated for use with magnetic loads.
