PSU Project

We are in the process of developing a compact all-in-one 10 "meeting room panel pc, where we have a 10" open frame monitor and a PC to be installed in a kind of box and hang on the wall.

The problem is to monitor and PC each have their psu. Screen uses 12v (1200mA) and PC user 19v (2,1-a). Is there any way you can settle for 1 psu for both. Then we can avoid having two power cables into the box.

There are three solutions:
1: Internal splitter from one inboming power connector to two power plugs. The best solution.
2: One 19V PSU, capable of delivering at least 60W. Output is split and feeds both the PC and a 19V -> 12V stepdown capable of feeding the screen.
3: One 12V PSU, capable of delivering at least 60W. Output feeds both the screen and a step-up 12V -> 19V capable of feeding the PC.

As You quite clearly is developing a commercial product, You can PM the billig-information.

If we choose option no. 1. Are you able to guide us in the right direction where we could get / buy a splitter that could be used?

As it seems to be a commercial project my answer is: No.

If You undertake the development of a commercial project, You should be capable of actually do the job.
If You're not capable of it, You must get what You lack like everyone else: order and pay for it.

I would like to pay for it, but I really don't know what I need or who I can contact. That's why I ask in the forum.

You say: If You're not capable of it, You must get what You lack like everyone else: order and pay for it.

Where can I buy anything like this?

Can the PC be adapted to run on a lower voltage than 19 V, or the machine simply replaced with a 12 V version?
Laptops use 19 V or so mostly to be able to charge the battery, while all the internal components needs just 5 V or lower.
Most computers (?) will therefore run just fine on 12 V, but without charging function and probably putting some more stress on the internal converters.
Clearly not a good solution for a commercial product.

Your best bet would be to replace the hardware so they can share the same PSU, or to order or develop a custom PSU with dual outputs.
