Dry type distribution transformer
max. 7.5 kVA, 12 - 48 V | Buck-Boost
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 trans form ers
can be connected for a wide range of voltage com bi na tions.
The most common use is to buck (lower) or boost (raise)
the supply voltage a small amount, usually 5 to 27%.
Buck-boost trans form ers are in com pli ance with NEC
