I wonder if that is a misprint. I know a lot of power supplies that actually
"don't care" if the input is AC or DC. So inputting 120 VAC works more-or-less
the same are 120VDC. Off-line switching power supplies were a great innovation.

Unfortunately the prices (even assuming a discount) look prohibitive.
