Introduction Sorensen SLD-Series DC Load
1-4 M540075-01 Rev C
CV Mode: (Constant Voltage Mode)
At constant voltage mode; the SLD-series Electronic Load will attempt to sink enough
current until the load input voltage is equaled to the programmed value (see Figure 1-7).

Dynamic Waveform Definition:
There are six parameters to generate dynamic waveform or pulse waveform: High Load
Level, Low Load Level, T
HIGH , T LOW , and Rise and Fall Slew Rates. The SLD-series
Electronic Load will sink current from the power source proportional to the dynamic
waveform, the definition for which is shown in Figure 1-8. The period of dynamic
waveform is T-high + T-low.
Dynamic frequency = 1 /( T-high + T-low )
Duty cycle = T-high / ( T-high + T-low )
