How Does a Converter Hold its Voltage?
A solar controller uses PWM but how does a typical RV converter do it? How much play is there up and down to hold it there? I have a 12v mystery draw I am chasing down, but in the middle of this, ...

From too much experience, I can safety state that no large cheap power supply I have seen will maintain rock solid voltage regulation from no load to full load.
The best of my bunch is a Lamda which within range varies an astounding .02 within a wide input and output range. It's cost induces sticker-shock.
Meanwell and Megawatt all droop .2 to .3 volts open/circuit vs a 2 amp load. My Chinese bench 0-60vdc 10 amp power supply droops to the hundredths of of volt.
