Power Supplies


[link to this post]
 
Has anyone come across a power supply - 400W or above that will work on a low voltage DC supply?

We are looking at a project in an environment where nothing over 50v is permitted. There is an excellent 12v supply - with very high current capability along with other voltages that could be used.

Laptops/notebooks are NOT suitable and the PC will need to be built with an appropriate supply.

Get a 12V DC to 240V 50Hz AC Inverter with adequate wattage! I am sure you may get this through the Amazon or other On-line Stores. One good point from Amazon is you may get some users' comments.

Good luck

And how will that solve the problem?

There are some here from a US supplier, so they do exist.

Those look interesting - just need to find a European importer.

Your Google searching actually achieved something! Mine didn't!

(although only 250w, you may be able to use a separate one for ancillaries )

dont forget most lcd monitors run a high voltage for the backlights, - might need to specify led backlight

They are sorted - they are LED backlit and have a 12V input!

I think you might struggle to get 400W at 12v input. Is there a 48v rail?

If so this might do the trick.

Otherwise if 300W isn't enough have a look at this site which has units going up to 700W

If you're really stuck with 12v and could actually manage with a smaller power budget then there's a 160W pico-psu which runs on a 12v supply, plus the car pc psus which have already been mentioned.

And how will that solve the problem?
It won't - I suspect that OCdragon didn't notice that the problem wasn't to run a PC on a 12v input but to avoid anything > 50v

There's loads of 48v stuff as that's the standard telecoms DC rail (see my other post) is that any use?
