Testing monitors that need power packs

[Amraks]

I am after something that will enable me to test monitors I have with out having to buy power packs and waste money if these monitors never go again.

Any idea's what I can use?

Re: Testing monitors that need power packs

Do you have any variable power supply?
What is the voltage and current requirement for the monitor?

Re: Testing monitors that need power packs

No I don't have a variable psu
14v 2.14a

Re: Testing monitors that need power packs

any suggestions would be good

Can you get the variable psu with DC plugs?

Re: Testing monitors that need power packs

The DC plug will be the problem since they are not standardized. You may be able to run it using fully charged car battery, but you will have to find the DC plug.

You could get a universal power adapter designed for laptops. Get one of those with tons of tips. Chances are at least one of the tips will work on most of the monitors.

I was thinking this but most range from 15v

Re: Testing monitors that need power packs

I've seen plenty of universal adapters with 14-24V (I think?) which should be enough for most monitors.

Besides, a 14V power supply should work for a 13V monitor just as well. And a 24V supply would work for a 25V monitor, if you know what I mean. The tolerances are not that tight anyway.

so I could just a dc variable power supply and use the clips?

Neg on chassis of monitor positive on the positive side of things?

Recycle a 19v DC adapter for laptops and then buy one of those LM2576 or LM25** dc converters from eBay : http://www.ebay.com/sch/i.html?_odkw...erter&_sacat=0

You can set any voltage between about 1v and input voltage, so you can do 12-14v no problems at all up to 3A.

Just forget about the jack, you can just open the monitor and solder the two wires straight to the board.

Re: Testing monitors that need power packs

I think I have it

cable pigtail 5.5x2.1mm jack

And

5.5x2.1mm Jack to 28 jacks


Would be what I am after to run off a variable power supply.

Re: Testing monitors that need power packs

You can buy the jacks separately, just search for "power jack set mix" in ebay.

The power supply in the ebay link is a very cheap and crappy adjustable power supply. I wouldn't recommend it even if you have the money.
