David,
I've read with interest most of your's and other's Megawatt/Meanwell/Etc. power supply posts.
I love the adjustable output voltage of these units - assuming their specs actually mean that they can in fact deliver their maximum amps while at the same time being set to, and hold, their highest specified output voltage.
Now ... here's what I would REALLY like if I could afford it: A power supply with adjustable output voltage AND simultaneously ... set-able input current draw.
The reason being I'd like to buy, say, a 50 amp Megawatt, set it to 14.6 output volts, AND set it's input current draw to 30 amps maximum so my little 550 VA Honda generator could drive it - and later set it to 50 amps input current draw if I should happen to later buy a 1600 watt Honda generator. In other words, have an RV battery charging power supply that could maintain any desired battery charging voltage on it's outputs while at the same time be usable with any restricted-size 120V AC input power source.
BTW, this concept does not violate any laws of any physics that I know of ... because my engineering group centuries ago had to program our automatic testers that had in them "full four-quadrant" power supplies: Up to their maximum power supply specs, the power supplies could be programmed to supply any output voltage at any output current that the load could take (positive or negative).
Does such an animal exist that you don't have to be an RV-loving Bill Gates to afford?? :h
