Cisco ASA 5505 directly wired to 48VDC

We need to install a few Cisco ASA's in our remote offices.  All of the equipment in those offices run on 48VDC.  We were told we would need to purchase 5510's with DC power supplies.  We though another option was to purchase 5505's and Wilmore 48VDC to 110VAC convertors.  Then, we looked at a 5505 and saw that the device was actually 48VDC, and the power supply that comes with it converts 110VAC to 48VDC.

So, we are trying to figure out if anyone out there ever wired a 5505 directly to a 48VDC power distribution panel?  Or, if anyone knows if this is possible?

I searched the internet for just a power picktail for the 5505, but did not find anything.

Unlike AC power supplies that produce a consistant power output, our batteries put out 53 VDC and below, depending on their charge.  We were hoping that the 5505 was like its big brothers and could work within the tolorance of 36 to 72 VDC.  Since I can't find that in writing, and no one seems to have tried it, it looks like we will just stick with the Wilmore invertors.
