Appx.
Constant-Resistance (CR) Mode
In constant-resistance (CR) mode operation, the current flow is proportional to
changes in the voltage.
The PCZ1000A operates as a resistive load as shown in Fig.A-6, within the range
shown in Fig.A-1. If the input voltage changes, the current flow changes
accordingly based on the specified resistance R, such that RMS input voltage/RMS
input current = resistance.

CR Mode
Transition points in CR mode operation
In Fig.A-7 below, the line F-G represents operation in CR mode, the line G-H
represents operation in CC mode, and the line H-I represents operation in CP mode.
As the RMS value of the input voltage (V1) increases, the operating point of the
PCZ1000A in CR mode starts from point F, then changes to operation in CC mode
on reaching point G. As the voltage increases further to reach point H, the
PCZ1000A operation changes again to CP mode (see the above explanation of CR
mode operation). Note that, depending on the PSET and RSET values, the operating
point may change directly from CR mode to CP mode.
