Load Current
Voltage-current Relation of CS Mode
Const Mode: load mode
Unit PF: Unity power factor
On: enable the UPF mode, at this situation, the current waveform changes
with the voltage waveform and this mode causes power factor to be as close
as possible to unity, useful when the input voltage is non-sinusoidal.
Off: disable the UPF mode, at this situation, the current waveform is not
affected by voltage Waveform, and the current waveform is subject to
defined in the config menu, the actual power factor is affected by voltage
Waveform, current Waveform, and phase shift.
Power setting: Constant apparent power value
Current AC Slew Rate: current slope
Waveform (phase shift range: -90.0~90.0): select the waveform. Under CC
mode, and Unit PF is off, Waveform can be select.
Crest Factor: CF range is 1.414~5, and the range is limited by peak value.
