Current slew rate is defined as the change in current over time. A programmable slew rate

allows a controlled transition from one load setting to another. The actual transition time is

defined as the time for the input to change from 10% to 90%, or 90% to 10% of the

programmed current values. The graph below illustrates slew rate measurements.

Figure 8 - Slew Rate Measurement

Between the 10% and 90% region, the slew rate can be measured by observing the steepest

slope portion. In case of very large load changes, e.g. from no load to full load, the actual

transition time will be larger than the expected (measured) time. For this reason, the firmware

allows the user to program slew rate values outside of the specified slew rate ranges. The

minimum transition time for all programmable slew rates is also limited in cases where the

transition from one setting to another is very small, due to bandwidth limitations of the load.

Constant Voltage (CV) Mode

In this mode, the electronic load will attempt to sink enough current to control the source

voltage to the programmed value.
