WARNING
If the setting value of of P
AC load will not load the UUT. For example, when voltage is 50V
users set P
loading current should be 20A
the AC load will not load the UUT, please adjust P
higher to the reasonable range value.

3.9.3 Inrush Current Mode

The RLC load network (Figure 3-10) can test the inrush current output of UUT. First, input the
load network parameter (R
can simulate the input angle during maximum inrush current output. I
needed to be set as well for the subsequent loading. (For the detailed information please refer
section 3.4.7.)
For switching to Inrush Current mode, the procedures are as below:
1. Press RLC/DC RECT key to go into the Rectified Load Mode.
2. Press 3 , then press ENTER to enter Inrush Current mode.
