This is a beefy switching supply, for when you need a lot of power! It can supply 5V DC up to 10 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 computer/appliance power cord) The output connects to a 2.1mm DC plug. There's a green LED indicator lamp as well. These will be great for people who want to power 5V LED strips or a lot of motors for a CNC project. Using a separate supply like this can be easier than trying to modify an ATX power supply as its smaller, quieter and has a plug on it ready to go!Technical Details Note: As of Wednesday, January 20th 2016, we are now selling this product with a 3 prong adaptor. * 5V up to 10A output * 110V-220V input * 3 prong adaptor for US/Canada/Japan - for other countries use a basic plug adapter. 112cm (44in) long cable * 2.1mm 3 prong output plug. 110cm (42in) long cable * Body size is 5.5" x 2.4" x 1.3" (14cm x 6 cm x 3.3 cm * Weight: 0.925 lb / 420g https://elecena.pl/product/22722244/5v-10a-switching-power-supply-discontinued 2023-03-07 https://elecena.pl/product/22722244/5v-10a-switching-power-supply-discontinued 2024-09-19
