TTi MX100TP triple power supply teardown and review
Robaroni:
I just turned mine on. When it first comes on the fan is louder for a few seconds then it quiets right down, at least that's what I found and I'm a stickler for noise, I sold my Keysight bench meter because it was too noisy for me.
I think the noise is relative to current draw but I've run higher currents and still had no objection.

Evodad:
Thank you for your answer Rob !
I am allergic to Fan Noise >:(
My choice is between the MX100T / TP or the PL303QMD /P.
The latter i less flexible from a voltage, current and output perspective, but lower Fan Noise if any, heavier but smaller in depth.
(I would like both !)
One other question. I am quite a fan of being able to change one digit at a time when setting voltage or current, e.g. ramping up
the voltage in 1 V increments.
This is indicated as possible in the manual under 'Spin Wheel Action -> single digit increment. It just does not explain how ?
How do you jump to the digit you want to increment ?

single digit increment
"single digit increment" doesn't differentiate each specific digit. You can't, for example, select the volt's ten digit and just advance it. Example 8.374 volts, we can't just advance the "3" or or.1 place. "Single digit" basically stops acceleration, no matter how fast you spin the dial the digit change is only by one digit (starting from the LSD). The accelerator works very well but you can't go from 6.418 volts to 7.418 volts in one shot. The way to do that is with the touch pad or spinning the dial fast then slowing down to the voltage you want.

Thank you for a quick and clear answer ! :-+
I have some TTI units at work with Coarse, Fine knobs but I prefer some other units with digit increments.
The MX100 seems to be somewhere in between with 'acceleration' action.

P.S. Don't you sleep over there ? :)
