ExportAPFC panel specification in PDF
PlatformWindows 10 and 11
What you get
- Step sizes chosen so the controller can reach the target at any load
- Detuning recommended from the measured or expected harmonics
- Savings shown against the tariff you enter
- Panel specification ready to send to the panel builder
- Capacitor current added back to Calc-Ax Cable for the incomer
