I'm pretty sure the 4011 doesn't have an internal power supply. I think it's just got a normal AC adapter, like 2011 and 3011. it'll also take 12-57v (same as the 1100AHx4, I think).
There's at least one model of CCR (a 1009, I don't know if they ever did that with anything bigger) that's made for DC and doesn't have an internal power supply.
