12 VDC 8.5A 100W Regulated Switching Power Supply
12 VDC 8.5A 100W Regulated Switching Power Supply is rated 4.6 out of 5 by 5.
Rated 4 out of 5 by from Compact, and adequate for Lepai 2.1!I found one of these at the PE Tent Sale for a great price to try out with the Lepai LP-168HA. Unloaded, the max VDC came out to 13.5 in my case, and 8.5A is perfect for the Lepai. They are only about 4.5" wide, so they fit most anywhere. Easy hookup. I do have a clear flip cover on my unit that is not pictured on this one, but that comes in handy. I gave it 4 stars, because the price can be hard to swallow for some instances.

Rated 4 out of 5 by from Decent little power supply.When I received the unit, it was a little banged up on the top grill cover, but I plugged it in and tried it anyway. It powered up and it worked like a champ. Instead of sending it back, I just pulled the dings out and it looks like brand new. I'm not using the full capacity of the power supply (about 5 amps) but it's operating cool and quite. The only drawback that I found was that there was no power switch. In some applications that will not matter, but I personally would like to have had one built onto the unit.

Rated 5 out of 5 by from Works fineI am running a small HF transceiver off mine. No problems with noise. The power supply has a nice set of screw-down terminals, well labelled. Nice quality item.

12 VDC 8.5A 100W Regulated Switching Power Supply

Should I put a fuse or some type protection between wall socket an the power supply if so what should I use a fuse or circuit breaker or power strip with surge protector

Asked by: cajunmal66

I'm building a amplifier and pre amplifier and i have been trying to use one dc output but get a hum i was wondering since this has 2 outputs would this work for my project or are the outputs connected inside the case to a single output.

Asked by: Computer Builder

Would it be possible to connect a 12V DC battery to this to power a Lepai amp? Looking to make a sealed portable boom box with a sub and a couple of full range speakers. 

Asked by: michelbrowngelo
The 12 volt battery should be able to power the amp by itself. This power supply would connect to 110 volt AC, which would be the outlet in the home

I just ordered this power supply and it had no manual, or any diagram on how to wire it up. any help would be appreciated? thanks.

Asked by: caifan21
The terminals labeled L & N (AC) are for the power coming from the wall. This is where the power cord gets plugged into. The Ground terminal is to the right of those and will not be used with the included cords. The -V and +V terminals are the positive and negative outputs for the device you want to plug into this. The small potentiometer to the far right is how you adjust the output voltage. A volt meter will be required to verify the output is where you need it.
