Buck and Boost Transformer Calculator - Schneider Electric United StatesBuck Boost Electronic Calculator, Calculates proper Square D Transformers to use when doing small changes in voltage: 5%, 6.6%, 10%, 13.3%, 20%, and 26.6%. Single Phase or Three Phase Application. Must use Open Delta. Use Open Delta if only need three wires for load. Use Wye configuration for all four-wire applications. Wye configurations offer expanded kVA Capacity - so try if Open Delta does not meet your requirment. Choose the voltage that will be used. (Buck or Boost). KVA capacity using the diagram.
