How do I select a Buck Boost Transformer for a direct-connected motor load?

Selection of Buck Boost Transformers for Motor Loads

Product Line:
LV Transformers

Applies to Buck and Boost Transformers by SquareD/Schneider Electric

Motor Loads can have high inrush or Locked Rotor Current when starting


Buck Boost units can be sized based on the full load current and voltage differential. Since the impedance presented to the circuit by the Autotransformer connection is low, a locked rotor current condition will not cause a large IZ voltage drop across the Transformer(s).
