Re: [Gumstix-users] Overo Power Supply *ONLY* works at 120 volts

[R. P. M. <log...@gm...>]

Don,

I think you should add the following to make it clear.

"For 120V/60Hz AC input power only. This power supply is not suitable
for 220-240V input".

I have seen other sites that say "for 120V/60Hz input" when the device
is capable of the full 90-264 volt 50/60 Hz input. Also, I though the
US used 110V? So your statement would seem to preclude use in the US.
Perhaps it would be even better to state the full input range as
specified on the PSU.

Your old CUI supplies were 90-264 volt input and I find that that
input range to be a requirement for our usage. Supplying only 120V
capable PSUs would mean we have to search for a compatible supply from
elsewhere.

Remember that other countries, like Thailand, use the US style
connector but with 220V/50Hz.
