Instructions:
Buck 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%
Calculator will then calculate Proper Square D Buck Boost Transformer and wiring diagram.
OUTPUT from Tool:
- Step One: Single Phase or Three Phase Application
IF Three Phase:
- Three wire source: Must use Open Delta
- Four-wire source:
- Use Open Delta if only need three wires for load
- Use Wye configuration for all four-wire applications.
Note: Wye configurations offer expanded kVA Capacity - so try if Open Delta does not meet your requirment.
- Step Two: Input Source Voltage
- Step Three: Start changing the voltage change percentage until desired voltage appears in either the buck or boost windows (Exact voltage might not appear, please pick closes voltage: 240 required from 208, 236 is closest voltage)
- Step Four: Choose the voltage that will be used. (Buck or Boost)
- Step Five: Input Load Amps
Calculate Load Amps by inputting Load kVA - Step Six: If source is 50HZ click yes for required
Calculator will then calculate Proper Square D Buck Boost Transformer and wiring diagram.
OUTPUT from Tool:
- Part number
- Units required
- kVA capacity using the diagram
- Wiring Diagram
- Options for printing and e-mailing
