Max ampere will blow my device?

Question

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.-- Regards,   Robert Monsen"Your Highness, I have no need of this hypothesis."     - Pierre Laplace (1749-1827), to Napoleon,        on why his works on celestial mechanics make no mention of God.

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.
