That part was called a "Univolt" as it was Airstreams first venture into using something for low voltage other than the battery.
It's really nothing more than a "transformer" with a dual voltage output.
It provides a 12 volt
and 19 volt AC output.
The 12 volt
output is used for the lights.
The 19 volt output is used for the ceiling fans.
The ceiling fans are 12 volt
DC motors, that work perfectly on 19 volts AC.
The 19 volts AC effective DC equivalent is 19 X .70711 which is 13.44 volts.
Replacing that transformer with a true Univolt is very easy. Simply connect all the output wires to the Univolt, making sure that you create separate circuits.
