The output voltage of the units can be increased to a maximum of 10%. This is comprised of a combination of the remote-sense and trim
adjustment. Do not exceed 10% of Vonom between +Vout and –Vout terminals. Also refer to ”O(jiān)utput Voltage Adjust” section and
Figures 31 – 35 for clarification.)
