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...

Thick wires hanging from the screw terminals could really fatigue the solder joints on the circuit board.
I wanted to remove this stress, While I work toward a more permanent mounting on my cabinet door. All the pictures in this post are taken with my Samsung phone, not the Canon DSLR. Not too bad though.
Those rails it rests on, are actually aluminum screen frames I had left over from a job. Was kind of happy to find these in the scrap pile.
I definitely wanted some space behind/ under the unit for airflow and this is about a 3/8" gap.
I have the screws into the bottom of the MeanWell recessed into the rails so it sits nice and flush on the door. The m4 screws were a little long, but were the shortest available. I shortened them and deburred the threads with a fine triangular file.
I chopped up the cheapowatt case for the mounting feet. Not the prettiest, but I'm about function. Prettification can be delayed or ignored.
Here is the GTpower meter with the case removed. The Aluminum 12awg wire has got to go, along with one of the 45amp powerpoles. I have some tinned 8awg from genuinedealz I am going to replace it with:
The two circuit boards sandwich the Negative wire. I have acquired a solder sucker gun and spent some time practicing on the cheapowatt, as to get to that negative cable by separating the CB's
I'm still not incredibly confident in my soldering skills, but I really want this GTpower meter inline, and the 12awg aluminum just gets too hot passing 40 amps.
It is mounted and operating as I type this. I have another small fan blowing at the front opening from about a foot away. It is providing 6 to 8.5 amps while I hold the screwy 31 at 14.7v. The solar was 25AH shy of the goal today.
The fan is cycling on for about 1 minute every 12 to 15 minutes.
I am pretty sure, with the help of other quieter fans, I can keep the meanwell fan from turning on at any overnight float loads I am likely to employ, and for bulk charging at 40 amps, Well I don't really mind the fan that much then.
Eager to get Westend's heatsink fan goodie package and fit more heatsinks to the exterior adjacent to the transistors.
Playing with the 10 turn pot mounting location too, and leaving room for a 4 hour timer, and perhaps a couple 40MM fans on a PWM speed controller forcing air in the front.
But for now, it is fully functional and does not require all the extra tinkering. But it will get it anyway.
