3.2.4 Constant power operation mode (CW)
Under CW mode, the electronic load will consume a constant power, as shown
below. If input voltage rises, the input current decreases and power P (= V * I)
will maintain at setting power. As shown in Fig. 3-4.

Under CW mode, the electronic load provides three ways to modify constant
power.
