Buck Boost Transformer

Buck-boost transformers shift line voltage up or down by a narrow margin, typically five to twenty percent, bringing a supply into the range the equipment was built for. Electricians drop one in when a 208-volt supply has to feed 230-volt equipment, when a long run has sagged the voltage at the far end of a line, or when replacing a whole transformer costs far more than correcting a few percent.

 

As an authorized electrical distributor for multiple manufacturers, we stock buck-boost transformers from Acme Electric, Hammond Power Solutions, ABB and more across competing lines, in single and three-phase with a range of enclosure types and frequency ratings, so you can match the voltage shift the load needs, compare enclosure ratings and dimensions across brands, and mount one in the space the panel has.
