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...

Thanks. I've learned a lot through this forum over the years. Thanks to all who have contributed to my knowledge.
Feels good to be able to minimize degradation of a Lead acid battery whilst cycling it deep and often, and this AGM's capacity retention is surprising me. The voltage it maintains for AH removed simply blows away and flooded batteries I've cycled before even much higher overall capacity of flooded battery. Whenever its performance seems to decline, 40 amps from the meanwell from 50% wakes it back up, and 2 high amp recharges back to back from 50%, even more so.
I was looking at pics of the meanwell interior I posted earlier in this thread and it appears there are two temp sensors internally. Certainly the easiest location to attach one of my thermocouples would be on an internal heatsink. I could attach more than one in different parts, but am not sure it is worth the effort. It is merely that i will be opening it up to clean the dust from the fan blades and internal components and reverse their flow when I solder the new Bourns potentiometer to the Pot leads.
I got one of these for measuring temperature of 4 different sensors at once:

Much more convenient that the DMM.
Perhaps trying to keep the Meanwell's 40MM fan coming on at all is wasted and unneeded effort, I just find experimentation, results and interpretation of them interesting.
My house loads never approach the level that the 40Mm fan needs to come on when the fan's noise would annoy me, it is only at 25+ amps that it comes on at all, and that basically only happens when the battery is depleted and can ask for everything. I put some self sticking cork 'feet' on the base of the meanwell where it attaches to the cabinet door which greatly reduced noise transmission, and with the door closed, the 40Mm fan is not really that loud, but the cabinet definitely warms more.
Anyway, I think it is awesome to turn a dial and have dial a voltage on both The Meanwell and the vehicle's voltage regulator.
Soon I will wire up my hall effect sensor ammeter to monitor total alternator output, measure its temperature at different load levels, vehicle speeds. Preliminary data shows that Idling with a hot engine and a well loaded alternator has its temp skyrocket compared to moving at higher speeds with rpms in the 1200+ range.
