content: Anyone have any science project ideas for what to do with a 685 amp 12 volt DC switch mode power supply? Input is 240 VAC * 54 A... 12,879 W.

content: Voltage maybe a bit low for welding - perhaps spotwelding.However smps's aren't good at taking that sort of abuse without shutting downIf you can get some massive carbon rods it would maybe make an insane arc lamp.And yes, pics please, inside & out

content: Sell it to a coiner? Problem is that most who have "free" electricity (college students living in dorms) don't have access to 54A of 240V.If the PFC stage could be separated and used standalone, it could be hacked into a battery charger for a DIY EV.If it is synchronous rectified, hack it to work backwards and connect a VFD to the DC bus in order to get a really big inverter?
