Time-nutters--

I was successful at getting 2 small Mean Well 15 V switching supplies
adjusted down to 12 volts.   On these particular models the output voltage
pot was in series with a resistor which limited the output adjustment 
range.
Swapping out the series resistor allowed trimming the output voltage down
to 12.0 V.

However, a different model Mean Well switching supply had no resistor in
series with the adjustment pot and I was unable to figure out how to drop
the output voltage down to anything lower than 14.2 VDC.
