This is a beefy switching supply, for when you need a lot of power! It can supply 12V DC up to 5 Amps, running from 110V or 220V power (the plug it comes with is for US/Canada/Japan but you can use any plug adapter for your country, or just replace the cable with a standard 'figure-8' cable)
The output connects to a 2.1mm DC plug. There's a green indicator light to let you know its working
These will be great for people who want to power LED strips or a lot of motors for a CNC project. Using a separate supply like this can be better than trying to modify a ATX power supply because the 12V outputs of a PC power supply is not stable across all current draws, unless you're also using the 5V supply heavily, as well.
Some customers have asked us why the label seems to say ".5A" instead of "5A" - there is a comma in front of the 5 that looks like a dot! It is really a 5A supply.
