[BBLISA] Looking for a solution to power 120VAC device on 208/220VAC circuit

Hi all:

At one of my companies colo-centers, we have a 220/208 VAC power
distribution unit in the cabinet. I need to power a 120VAC wireless
access point which takes in 120VAC @ .3 amps (36 watts or so).  It's
not worth getting a 120 VAC circuit installed for this.

While I could probably jury rig a cable that just connected a hot and
the neutral, that breaks so many rules. So I am looking for a
commercial transformer that can do the conversion.

All the stuff I have seen has european style plugs and not US standard
plugs. Ideally the device would have an IEC C13 (shielded) plug on
it. To make it more fun, I think there is a short cord that connects
the IEC C13 to a NEMA 5-20R (yeah I know) since I seem to remember
plugging my laptop (which supports 120-240VAC) in there.

I suppose I could also try to find a 240 VAC transformer to DC and
just replace the 120VAC transformer that came with the access point.

Does anybody have any pointers/ideas/recommendation on how to power
the access point?
