Under the config menu interface, the user can select Const Mode item and set
the mode to CC.
⚫ 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.
⚫ Current AC: Const current value and current slope
⚫ Current DC: Idc setting value and Idc slope, Realize the function of AC+DC,
DC offset setting range is 10% of the rating.
⚫ 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.
Phase shift: Phase shift of voltage and current. Phase shift range within -
90°~90°. If programmed is positive it will be a leading power factor. If
programmed is negative it will be a lagging power factor.
Programming the load value (CC)
The user can press [Set] and set the input current value in the main interface of
CC mode. Directly set the present value through the knob or press numeric keys
to input the value. In case of wrong input by numeric keys, press to
delete the present input.
