Hi,
I own a Whirlpool/Jacuzzi which among other things has a built in Stereo with 2 Speakers and a passive Subwoofer.
The Pool Manufacturer fitted a Marine Style Radio (looks just like a Car single Din Radio, but is waterproof) which obviously runs on 12V DC and a AC->DC power supply to get 12V from my 230V wall power.
They designed this thing in a way that you can conveniently switch on your music with the included remote.
For this feature to work they simply didn't switch the 12V power supply (Millenia Spa Power8, Boars says:LG 100W 1.1).
So this poor power supply was on since 2008. 24/7/365. It died end of last year.
I disassembled it. The thing is enclosed in a rather large black container that is secured with those bloody secure flathead screws.
The supply looks just fine, it's an LG 100W model. No blown caps, no obvious heat discoloration or anything.
But the caps & semiconductors are both no name, it doesn't lack any output or input protection though.
I don't really fancy working on an power supply that is connected to the mains and I don't own an isolation transformer (got a Fluke 17B+ though).
And this thing has done quite some hours probably (8 Years of 24/7)...
So I quickly looked up 12V 100W power supplies on mouser. Found a delta that looks fairly good and is cheap (30€). Should fit in my black box.

I guess the load I am applying will vary a lot. Is this Delta suited for this task?
Thanks a lot allready
