Outback Power Systems FX SERIES 3. OutBack Series, 4. OutBack Series/Parallel

24
3. OutBack Series
• 2-10 FXs are wired to two 120VAC output legs producing 240 VAC between them.
• This system requires an FW-X240 or PSX-240 Auto Transformer.
• 240VAC can be produced on one leg if the load is ten amps or less; an FX on one leg can power
loads on the other leg, helping to balance loads.
• The AC input source (generator or grid) must be 240VAC between both legs.
4. OutBack Series/Parallel
• Unique to OutBack, the loads are balanced between two 120VAC legs, changing between series and
parallel as needed.
• An FW-X240 or PSX-240 Auto Transformer is required to balance the loads.
• This system allows for larger AC loads without overloading either of the FX 120 VAC outputs; it also
allows for 240 split-phase using only one FX.
