1.1.1 Operating Modes
The operating modes of the SLD-series Electronic Load include Constant Current (CC) mode,
Constant Resistance (CR) mode, and Constant Voltage (CV) mode. The wide range dynamic
load with rise/fall current slew rate is available in CC mode only.
CC Mode:
(Constant Current mode)
With the operating mode of constant current, the SLD-series Electronic load will sink a
current in accordance with the programmed value regardless of the input voltage (see
Figure 1-5).

At constant resistance mode; the SLD-series Electronic Load will sink a current linearly
proportional to the load input voltage in accordance with the programmed resistance
setting (see Figure 1-6).
