I have not noticed any speed regulation on the fan.
Inside the Dell EPS-470 there is an ATX connector with 12V supply. Iâm going to use it to power a 120mm fan.
For those that want to use an ATX or other simular low voltage power supply this same company just released a new buck/boost version of the power supply module.
It outputs 0-32V and the input is 6-40V with a 5A max current.
This really opens the door for more compact and easier to build power supplies if you do not need the higher current and voltage abilities of the DPS5015
It is on sale during the introduction for $28.99 for 3 days, grab it while you can, they always do this when released and the price DOES go up after that.
Great, glad to see an official test. Basically what I figured it would show.
Please post how those projects go. I already have people asking what can be done with COBâsâŚ
FINALLY
my power supply arrived.
Not that hard, the magenta curve shows the power loss in it. The maximum is about 10W in all the test I have done, the only significant exception is when I am very close to the current limit.
Here is the Design for the Acrylic case I made in case anyone wants to make one. It is cut out with a laser cutter from standard hardware store .08â acrylic sheet (âplexiglassâ). Thicker acrylic would be stronger but costs a lot more and is much harder to find.
Proper acrylic glue will be stronger and look better but hot glue or super glue works just fine as well.
It has been over 3 months since I posted my plans for this âbuild it yourselfâ power supply in Post# 73 of this thread. Here it finally is.
Parts Used:
Dell EPS-470 Power Supply, output rating 4mVdc, 9.6amp (Added power switch) $27.
DPS5015 buck controlled power supply $38.
Cooling Fan, 50mm 5v $8.
Connectors for test leads $10.
Misc. scrounged box and hardware $0.
I am quite pleased with it and thanks Texas_Ace for all your assistance.
Looks good! It is always interesting to see peoples different build styles with these.
I am impatiently waiting for my DPS5015 to arrive.
I contacted the seller through AE and asked if he was still doing BLF348 discounts,he said not officially but he would sell me one for $34.
I submitted an eBay âmake offerâ on one of the EPS-470 power supplies and scored one for $25.
Looking forward to putting it together, mine is also going to be assembled in a âcaseâ made of whatever I have laying around.
Big thanks to all in this thread and elsewhere who dream/scrounge up these great budget ideas for the rest of us to steal.
With the DPS3012 is that a power supply supplied with the control unit, ie I donât need to buy a separate supply for it?
All of the modules in this thread need a separate power supply for them to work.
I received mine in the mail earlier this week and havenât had a spare minute to even unbox and test it! Itâs driving me crazy!
This weekendâŚ
Is the DPS5015 the highest power unit of this brand?
No DPS over 750W?
It is the highest at this point that I know of.
Ah right. So Iâm guessing the external board connected to the DPS3012 is just because the control unit isnât big enough to contain the beefier components?
Yeah, for that kind of amperage you need way better heat sinking then the self-contained display setup allows.
Thanks, suddenly all becomes clear.
