Rated 5 out of 5 by from 12vdc power adapter 3aI'm using this to power up a home built led lighting project. It does the job very nicely. I built an led light array with micro switches to give lighting for lower kitchen cabinets. Lights come on when the doors are opened. All doors can be opened turning all 66 led bulbs. It powers them all just fine.

Rated 5 out of 5 by from Parts Express Cannot Be OutdoneAs usual, when I need a component I turn to Parts Express and they never let me down. They always have the items that a serious tech buyer requires. This case is no different. I needed a solid 12V @ 3ADC supply, and yes! there is was at Parts Express. The product fits my needs perfectly and the shipping is always fast!

12 VDC 3A AC Power Adapter with 2.1 x 5.5mm Plug

I have an RCA DECK215R 22 inch TV with power supply Model CP1240. input:100 -240VAC, 50/60Hz 1.8A. Output: 12V 4A. Will this power supply work for my TV?

Asked by: kjcamara
Unfortunately no. If the power supply you need is 4A, you will want to replace it with something that is 4A or higher, as long as it is a regulated power supply. Something like below will work but we cannot guarantee the plug size is correct.http://www.parts-express.com/12-vdc-5a-switching-power-supply-with-25-x-55mm-plug--120-056

Will this power cord work with Lepai LP- 269FS 4x45W mini amp?

Asked by: Zoey
yes.
Answered by: TomI
Date published: 2015-04-05

will this fit on all lepai amplifiers?

Asked by: jo marble
Yes for most of the Lepai amps the parts express carry. (2.1mm connection.) The large class D LP7498E uses the 2.5mm plug.

Is this power supply regulated? Is that what over-current and over- voltage protection mean? I need a 12v DC 2.5A supply capable of handling 20W with a 2.1mm adapter barrel. Would this one work?

Asked by: landerson
This is indeed a regulated supply. That just means that this maintains 12 volts no matter what the current draw is. That is what the over voltage protection is. The over current will shut down the unit if too many amps start to flow in case of a short or something of that nature.This sounds like it will work well with your stated application.

I just purchased the SURE 2x15W @ 4 Ohm TA2024 Class-D Audio Amplifier Board. Will this be compatible with it? A friend recommended a vudu power supply but I am not sure which model or how to get one as alternative. 

Asked by: MindfulMoz
Yes this power supply will work well with that amplifier.

I need a new power supply for my Acoustic Authority 5.1 A5640 5.1 Speaker System. I'm looking at Part Express PS-SP11111. The input of Acoustic Authority power supply is 120VAC, 60hZ, 65w and output is 15VDC 2450mA. Will it work?

Asked by: MikeinKannapolis
Unfortunately no, you will need a power supply that has 15V output with 2450 mA capacity or higher. The only 15V power supply we have is for a Peavey product and only offers 1000 mA output.
