I read, and reread the instructions to decide which mode of operation I wanted. I set both potentiometers to the full counter clockwise position. (The potentiometers are 20 turn devices.) Then I fed it the maximum voltage to which the unit is exposed, at 16v, and set the voltage 'in' pot to match that voltage, on the display. Then, I set the current limit pot until the unit supplied full speed (Required current)to the fan needed in my application. Then, I set the input voltage to the 12.0 volt minimum voltage the fan will see. The result is exactly what I want. I cycled the voltage input, several times. I powered the unit 24hrs, and tested hi & lo input voltages. It works perfectly. The output voltage and current remained constant. Note: If a person was careless with setup, he/she could burn the unit, in my opinion.

Forgive me for a too detailed explanation. I am a retired electronics technician by trade.

Perfect

Product functioned as described. No hardware to mount the unit in my project.

The supply seems to work well for its intended use. No mechanical drawings/CAD models available to incorporate into a prototype design, though.
