power supplys

possibly a little off topic for you guys but please humour me.
i've got this electrical device which requires a 5 volt input and 2A max
supply. what the hell does the max mean?? can i use a supply which provides
less current?? in general how important is it to match an exact power supply
for a component? for instance would the above device run fine with a 6 V 2A
supply?

cheers

5 volts may signify TTL logic circuits an it will need a regulated voltage.
The supply must be capable of 2 amperes or more current.

Supply should be 5 volts +- 10% and more than 2 amps, like 2 to 5 amps.

You can always use the "try it, fry it" method of electronics design.

thanks both. will haveto try the "try and fry" i guess. cheers

 

[Phil]

an interesting idea but this is a little beyond my electrical know-how. i'll
speak to one of my boffin mates to see if he can do what you suggest.
cheers.
