which power converter to buy?

[dwpang]

Hi i have a screen device which runs on the following specs:

[Us] rated supply voltage 24 V DC
Supply External source
Supply voltage limits 19.2...28.8 V
Inrush current <= 30 A
Power consumption 28 W

So i went to the electronics store, however, I am confused about buying which type of power converter. They have like 24vdc 1/2/3/4/5/10/15/20/30A power converter. So which power converter should i buy? the 24vdc 1A one as due to the power consumption of 28W? or the 24vdc 30A as due to the inrush current? or a 24vdc 20A would suffice?

Thanks

You would be best off looking at the original power adapter, but its better to go too big than too small, it shouldnt draw more than it needs at any give time so having the capability of going to 30A would be good, but I suspect that the 15 or 20 would be fine in most cases

Dont take my word for it, see if you can google the device and see what it had for a power adapter

Are you sure that you don't have a missing decimal point? Inrush current<=30A. That's 720W @ 24V!

What is the "Screen Device"?

hi ya i am pretty sure. i copy and paste the specs from the catalogue.

the device is a human machine interface.
