Appendix C: Notice
Appendix C: Notice
1. CC and CP mode:
When loading under high frequency, for CF>1.8 and the minimum PF, if the voltage
drops under 7.5V, the loading current will decrease automatically to ensure the voltage
is kept above 7.5V. At this moment, no warning message will be shown on the display.
The specification for I
p
(max) is 135A, when the I
rms
x CF > 135A, then both of the I
rms
and CF will not be able to meet the setting values. For example, when setting I
rms
= 45A
and CF = 4, the actual loading may not reach the setting values.
When there is an inductor in series with the AC load, under high frequency, high current
and high CF, OVPP(over shooting) will be occurred. OVPP will be occurred when the
Vpeak is over 600V.
2. RLC mode:
When changing the PF value under Load ON, due to the AC Load algorithm, the response
time of changing the PF value may be slow, taking as much as 5 seconds before the PF
value is changed to the setting value. However, when changing the PF value under Load
OFF, the PF value will be immediately set at Load ON. Therefore, we suggest changing
the PF value under Load OFF instead of Load ON.
