Can CCR2004 be powered directly to the board using 24 volts?
Others CCR usually have written on the board 8-56v, so they can be powered ranging from 8v up to 56v, but this model (CCR2004) only have written12v.
I know could use the PW48V-12V85W power supply, but it's hard to find this model in Brazil at this moment.
My suggestion to Mikrotik is to deliver this model with one AC and one DC power supply from factory.
