Notes:
1)
MDL252: User can allocate up to 250 W to either channel up to 300 W total (e.g. 50 W/250 W, 250 W/50 W, 150 W/150 W).
2)
Fast pulse trains with large transitions may not be achievable.
3)
The slew rate specifications are not warranted but are descriptions of typical performance. The actual transition time is
defined as the time for the input to change from 10% to 90%, or vice versa, of the programmed current values. 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 time. The
load will automatically adjust the slew rate to fit within the range (high or low) that is closest to the programmed value.
