SolaHD™ Buck-Boost Transformers

Buck-Boost Transformers provide a compact, energy efficient, low cost means for raising or lowering voltage by a relatively small amount – usually 5 to 27 percent. Buck-boost transformers are typically used to power control panels, landscape lighting and other loads with specific voltage requirements that differ from the available line voltage. The proper buck-boost transformer can maximize the performance and life of the connected equipment.

Features

  • cULus
  • Small, single phase, dry type distribution transformer
  • Dual voltage primary and a dual voltage secondary
  • Transformers can be connected for a wide range of voltage combinations
  • In compliance with NEC Article 210.9, Exception 1 when field connected as an autotransformer. They can handle loads up to 20 times the nameplate rating
  • More efficient than equivalent isolation transformers
  • When the primary and secondary windings are connected it becomes an autotransformer, allowing it to supply a load with a much larger kVA rating than the nameplate indicates
  • Connected as an insulating transformer, the transformer’s capacity matches the nameplate kVA rating
