Buck-Boost transformers are small, single phase, dry type distribution transformers designed and shipped as insulating/isolating transformers. They have a dual voltage primary and a dual voltage secondary. These transformers can be connected for a wide range of voltage combinations. The most common use is to buck (lower) or boost (raise) the supply voltage a small amount, usually 5 to 27%. Buck-boost transformers are in compliance with NEC Article 210.9, Exception 1 when field connected as an autotransformer.
- Applications
- Features
| 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. |
| Compact, Lightweight, Can be connected as an autotransformer. |
| Low cost, compact size and lightweight |
| They are more efficient and cost less than equivalent isolation transformers |
| They can handle loads up to 20 times the nameplate rating |
| A buck-boost transformer is the ideal solution for changing line voltage by small amounts |
