48V5A Power Supply Used for Equipment Such as POE Switch, CCTV Camera, LED Strip Light, DC Pump Fan, etc. (48V Power Supply 5a 240W)

What's more to say? This will squeeze more watts from your little Fosi Audio V3 amp. Nuff said.

I got this to use with a Fosi Audio amplifier in case I needed more power. This power supply is very expensive: it costs about as much as the amp itself. It is also very large and heavy. The Fosi comes with an adequate power supply and is plenty loud with the one included. Unness you know for sure that you need this, I would recommend that you skip it, and run with the power supply that comes with the amp.

I used this to provide power to an industrial PoE switch using the two-wire break-out connector. Not much to say other then it works and I'm happy with it.

I'm not an electrician nor do I know anything about electricity. I ordered this power Supply to power up some LED strip lights (I read LED strip lights in the description). Not exactly sure if it was the power supply having to many volts or just cheap LED lights, but the powered on for a min and then started smoking. So I quickly unplugged them and I ended up tossing them out in the trash. To dangerous for my liking, and now I'm a little weary about trying this power supply on anything else.I will say this power supple seems built well and has different size connectors, which is nice. It is a little pricy but again it seems heavy duty.

This power adapter seems pretty well built overall. None of the barrels fit my application unfortunately but the small test I did run make me think this is sufficient for POE applications or hobby interests. I measured 48.78 VDC output while it was on. The connectors shown in the picture measure as1: 5.5mm OD, no internal pin2: 6.2mm OD, no internal pin3: 5.4mm OD, no internal pin4: 5mm OD, internal pin5: 4.8mm OD, no internal pin6: 3.9mm OD, no internal pin7: 3.4mm OD, no internal pin8: 3mm OD, no internal pin9: 2.5mm OD, no internal pin10: screw terminal adapterThe only negative that I can find is that the power on indicator light on the power brick is very bright.

This PS literally popped up free on Vine for me just a few days after I had purchased the Fosi Audio 48V supply for my V3 amp. I figured I could compare side by side and send back whichever I don't want. Similar size and heft as the Fosi. If anything it sounds better than the Fosi. I swear the presentation is smoother and warmer and the soundstage deeper. Plus it has a standard ground IEC plug instead of the stupid, awful, terrible, no good figure 8 connection. The 48V headroom is definitely superior to the included 32V supply. I also have an Aiyima A07 so I might just keep both so I have one to lend out to friends I'm trying to convert to the hifi hobby.I'm running an OPPO transport>Denafrips Pontus II (v1.4), Fosi V3 with Sparkos Labs dual discrete opamps>GR Research Encore MTMs. All Monolith interconnects. This things sounds freaking amazing for <$300 all in. The Sparkos op amps are half that. Worth it IMO. With dual to single chip adapters, a quad of OPA1656s sound 70-80% as good as the Sparkos for 25% the price. My current reference amp is my Primaluna EVO 300 integrated with Amperex 7316s in the preamp section. My tube collection includes virtually every pair of desirable 12AU7s out there, too.Pro tip: the 1950's Tung Sols with the black glass are in my top 5 pair at only $100 a pair. That's compared to Tele smooth plates, Tele ECC802S, the Bugle Boy 7316s, Seimens silver plates, '56 Radio Technique 12AU7WAs, Mullard long and short plates, Tektronix selected RCA cleartops, etc.Still listening at loud volumes. It's definitely less fatiguing than the Fosi supply. Don't hesitate.

Have a few aiyima and a fosi bt20aPower supply makes a nice power bump for all with quite a bit of audio quality and quantity benefits.The fosi sounded like garbage to me with no power for speakers with the included PS. This PS at least makes it loud enough and improves quality to tolerable.Recommended

This seems like a heavy duty power supply but it didn’t work for me but the device might be blown so I won’t fault the power supply. It has a lot of plugs for options and might work for others.
