Max ampere will blow my device?

Hi guys. I have a LCD monitor. I lost the power adaptor for it.
I bought a replacement.

My LCD monitor power requirements are: 24V DC, 2.4A

My power adaptor is: 24V DC, 5A Max.

Question is, if the adaptor is 5A max, will it blow my LCD monitor?

Thanks

No, it's fine. Your monitor draws only what it needs, which is less than
2.4A.

Maybe, but not likely. It partly depends on whether the original
supply was regulated or not.

The question is how much voltage does the new unit produce with load
current much less than its maximum specification. If it is regulated,
no problem. I would want to test it for no load output voltage and
with a dummy load that pulled something near the rating of the old
supply (a big 10 ohm resistor, perhaps). If there is less than a
couple volts extra (10 extra) at no load, it shouldn't do damage.

Not likely. Amp requirement is a minimum, not a maximum. A
bigger-than-required amp capacity will simply go unused, doing no harm.
A lower-than-required capacity may very well cook the supply, but
*USUALLY* won't do any harm to the device. Note the stress on
"usually"...

I went through this excercise with an accountant that thought he knew
something about electronics. We installed a larger than necesary power
supply on a PC just for the reliability factor.I explained to him that is
was a power supply not a power demand.....I don't think he ever quite "got
it".
Yeah, it should be fine.....Ross
