                                      Buck-Boost Transformers
Buck - Boost Transformers

Buck-Boost transformers are single phase, four winding transformers designed for two purposes:
  1. A low voltage isolation transformer for use on 12, 16, 24, 32, or 48 volt circuits.
  2. Used to buck (lower) or boost (increase) line voltage to match required load voltage.

Buck-Boost transformers are used to correct consistently low or high voltage conditions, where the voltage difference ranges from approximately 5% to 27%. Dongan Buck-Boost transformers are simple and straigt forward to specify, size and connect. Each transformer shipped from the factory is equipped with a simialar chard to assure ease of use at the installations site.
