Would this run Kessil A360X's and MP-10s?

No the Kessil runs on 19 Vdc, and the MP-10 runs on 24 Vdc. You may be able to get a 24 Vdc Power Supply from Amazon. Adjust the trim pot to 19 Vdc, and and run the MP-10 off of another 24 Vdc Power Supply. I never run a Power Supply at more than 90% of its rated Output. So the output rating would have to be above all your devices hooked to that particular power supply. BTW, for the CNAweb Cabinet, you’ll have to call their 800 number, to get that particular cabinet. If you aren’t familiar with working with Electronics and Power Supplies, don’t do it! I have close to 30 years of building control systems, and at one time held an employee UL certification.

Anyone see this, I’m going to check the prices at ACE, with my coupons. I already have the EGO batteries.

Returning to the hobby after 22+ years away I was surprised with so many power connections/ bricks. I originally ordered one CRST metal power strip with switchable outlets for both tanks not paying all that much attention. Well the main tank now has three strips for 18 plugs and most are full. Plus a UPS with the return pump connected to it.

Some of the supplies shown here are great. If I ever build a real tank again (this one is only 112 gallons) I will surely consider. There is of course a risk of single point of failure but also with a centeralized supply or two I can get higher quality supplies and maybe even more stable output so the DC returns are more stable (darn Red Sea downfall and DC pump looking at you). Thanks all for sharing your systems

Depends on the vintage... I have older

This. I ran something similar, just with a bank of cheap 12-24vdc online control relays to handle some basic on/off switching.

I use my Robo-tank controller running reef-pi for on/off switching. The 12vdc power supply feeds the Robo-tank directly and 24vdc is switched via the ground wire.

I really like the idea of running a DIN rail with various DIN mounted power supplies as needed. They're typically cleaner power, and certainly more reliable than the stupid bricks that are supplied with our various hardware. I think this'll be my next project.
