3.9 AC Load Simulation -- Rectified Load Mode
The general AC products like UPS and AC SOURCE often use rectified load to test their
features as Figure 3-8 shows. Based on the load network, rectified load mode is designed into
three sub modes – RLC mode, CP mode and Inrush Current mode.
The operating frequency should be lower than 70Hz under Rectified Load
Mode.

3.9.1 RLC Mode
For switching RLC mode, the procedures are as below:
1. Press RLC/DC RECT key to go into the Rectified Load Mode.
2. Press 1 , then press ENTER to enter RLC mode.
