Pulsed Transient Operation
Example 1:
Assume that the load is in external triggering mode, set the load current value to periodically switch between 1 A and 5 A;
set the time for rising edge (TimeR) to10 ms; set high level time (TimeH) to 200 ms; set time for falling edge (TimeF) to 10 ms; the load
is in pulsed transient operation, and a trigger occurs at this time.
