Meanwell SE-200-15
For those who don't know, this is a regulated DC power supply up to 15V. Got one, to charge my car battery "properly" :)... All is good, adjusts volts all the way to 15. One question: Is there an...

My Meanwell RSP-500-15 had a 1K OHM potentiometer, which I removed and replaced with wires which lead to a 1K ohm 10 turn potentiometer of dubious quality. Some Caig f5 Fader lube mostly cleared up the dubious factor, but I think I will need to open it back up and respray it every so often, so that dialing in voltage to 0.01 is as joyful as it is at present.
My Cheapowatt, also used the 1K ohm potentiometer, and this was much simpler to remove the potentiometer and add wiring leading to the 1K ohm 10 turn potentiometer, compared to the MeanWell.
How I wish there was a good plug and play 3 stage charger I could recommend when asked to do so. The B&D/ Vec1093 seems to be the favorite here but it is not inexpensive, nor always available. My Schizo Schumacher sc2500a could not be trusted to either fully charge, or not seriously overcharge when left alone.
My Bluesky sb2512i solar controller with IPN pro remote at least gives me the option of choosing absorption voltage/ duration and has a threshold of amps which triggers an adjustable float voltage. Unfortunately my roof space is limited, and 200 watts is not quite enough to achieve the 'recommended' 10% rate for most of the year of my still screwy 31 USbattery.
I've often thought of feeding the solar controller with a power supply for its ability to program a more desirable charge algorithm.
