Replacing a failed Robertson AP300DLX. The hydraulic pump works fine so I'll continue to use it - it's RPU160 and it's always seemed sufficient for the boat, with my old Robertson computer having an output of 10A. The RPU160 is spec'd at 6 to 10A drive current
The question arises since Simrad
documents recommend, to drive an RPU160, an AC42 computer which has an output of 30 to 50A. This seems like extreme overkill. The Simrad
AC12 would seem to be a better, and much cheaper match to the RPU160. The AC12 specs say output current
8A continuous, 16A for 1 sec.
Simrad docs don't imply any other difference between these two AP computers
Especially like to hear from anyone using an AC12 to drive hydraulic steering
and even better if they have the RPU160 pump and with experience in downwind steering
