Dongan offers a broad range of products for buck boost applications. These transformers are shipped as low voltage isolation transformers that can be easily reconfigured to buck or boost a wide range of voltages. The beauty of these transformers is that, in addition to being an inexpensive solution to isolation transformers, they are easily adaptable to most minor voltage corrections and will work on single or three phase applications. Buck boost transformers are physically smaller and lighter than the corresponding kVA of an isolation unit.
A 2 kVA buck boost transformer can do the work of a 7.5 to 32 kVA isolation unit depending upon how it is configured. Dongan offers the 85 series, which is encapsulated with 115°C rise; the 80 series which is ventilated with 115°C rise; and the 35 series, ventilated with a 55°C rise. All wiring is done in the field by a licensed electrician. If you prefer a pre-connected auto transformer instead, please consult our catalog for 34 and 84 ODY series products, or call us for assistance or further information. We will also help you through the connection of the buck boost transformers.
