Mean Well RSP-500-15 Switching Power Supply
IT just arrived. Initial impressions: Much heavier than the cheapowatt 1/2" wider, 1/2 inch longer and almost 1/2 inch less High than cheapowatt. The casing is about 50 to 75% thicker aluminum t...

Well, Mex gets special leeway for crossing over into obtuse tangent land :)
I'd love to see the cheapowatt infused borg/frankencharger have its own picture rich thread, and a performance breakdown when complete.
My modification abilities are limited to better heat dissipation and a 10 turn voltage pot, so I needed a more capable soup stock to begin with. The cheapowatt was a fun learning tool/ experiment, but i ultimately needed something that does not require constant twiddling to keep it from blowing itself up, and the MW met those demands admirably, for 127$ delivered.
I've no real issues extending this thread on tangents, but I have found in the past that finding certain information at a later date to be difficult when thread drift occurs, and memory, and the search function fails.
Once I get the heatsinks shaped fitted and thermal adhesived in place, and the 10 turn pot mounted a little more permanently, there is not really anything more to add to this thread.
I won't be doing any more data logging until a battery change, and I need to assuage my curiosity as to how much for how long a new battery can handle the MW's power.
For now I have quite a feeling of satisfaction knowing I can deliver 40 amps anytime I desire and when the battery can accept that much, and have grid power available. My schumacher was an untrustworthy 25 amps that had to be tricked whenever the solar had batteries above 12.8v, but still well from full. The Schumacher was a very poor power supply, with wild voltage swings occurring with a cycling fridge or mattress heating pad. Granted a task for which it was not designed.
The MW can hold any voltage rock steady under those same loads.
The MW is plug it in, and dial up the trim pot, and watch that SG rise. In 2 hours or so I can do a 50 to ~95% with some observation and voltage pot tweaking to hold constant current a bit longer.
The Schumacher needed to be monitored too, as it would occasionally blow past the high 14's and bring a battery to the mid 16's at an abusive rate.
