Sure Electronics 12 VDC 8.5A 100W Regulated Switching Power Supply
May I assume this power supply is preset for 120 volt input? I downloaded spec sheet from your website, but should they be in the box? And the AC power cord included has a connector that doesn't mate to the unit.... Odd.
You will want to check the switch setting on the unit when you receive it, there is a yellow sticker on top pointing to the switch. The one I pulled from stock was set on 230V input, but this is easily switchable with a small screw driver through the holes in the aluminum case. The power cord included should have been bare on one end to plug into the AC input on the barrier strip.

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.
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.
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.
