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

can this power and amp and charge an ipod?
can this power supply be used to power the Dayton Audio DTA-2 Class T Digital Audio Amplifier Module as well as run power to an ipod dock to charge an ipod or iphone? perhaps with some extra parts?
The DTA-2 requires a 12 volt power supply that gives at least 2 amps. This will fit the bill nicely to power that amp.As for an iPod dock, it really depends on the dock. Most docks are designed to get power over USB, which is 5 volts at up to 1 amp.So, there are a few ways to do this.1-The easy way: Buy an iPod dock intended for use in an automobile. These are made to run off of 11-14 volts, so your 12 volt supply will work great. These can be found with a bit of Googling. Then you can wire the 12v power source right to the dock's power cord.2-The DIY (manly) way: Use a voltage regulator to change your 12v into 5v. I have linked the proper regulator below. Look up the 7805 datasheet for a proper circuit. This will require a bit of soldering, the regulator, a heatsink and a couple capacitors. This will allow you to provide 5v power to a regular USB powered iPod dock.3-The h4xx0r way: You could use an existing 12v->5v transformer, like those intended to allow people to charge USB devices in cars. I have one linked below. Wire your 12v power to the end that would plug into the cigarette lighter, solder securely. Then you have 2 available USB ports on the other end that can provide adequate 5v power to any USB devices that may need it, including a regular USB powered iPod dock.Whatever you decide to do, have fun and be safe!

Will this fit the Lepai TriPath amp? It seems to have more current
Yes, the connector on this power supply will fit the Lepai TA2020 amps.
