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 UL approved! 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.   TECHNICAL DETAILS
