 |
|
Without getting into the debate of IR vs Ext regulation, can a IR alternator be used in the Z12 system? Will the EXT regulator for the SD20 play nice with the IR of the main Alt? I have a buddy who has flown his RV8 for years, he is a EE major and loves the IR alternators. I respect his opinion and for cost sake I want to use the IR alternator, but I am designing my system with the Z12 diagram. My concern is will the SD20 regulator function properly with this, my guess is it will since it is just looking at the buss voltage to tell itself to start putting out power. Thanks for any help.

Sure . . .

They never have to play together. One works or the
other works. Not both.

You are correct. But consider too that IF the
reason your main alternator is down is
due to an OV condition and there's no
automatic and effective means for taking
it off line . . . having a standby alternator
may be a moot point.

My system on an RV-10 is very close to what you describe; a Plane Power
60 amp main IR alternator and a B&C 20 amp standby with B&C external
linear regulator. System is wired very close to Z-12 and is working
fine.
