Replacement for diode array

[fliier]

A question. . .

When I built my RV6A back in the 90's I followed a Bob Nuckolls Schematic that called for a Primary and Secondary bus that relied on a diode array to power the primary bus during normal operations. It actually works well but with one drawback, the diode array pulls the voltage down over a full volt.

With the original avionics installation there was rarely an issue, but some of the newer avionics I've installed are giving me low voltage warnings. Essentially I now have to throw both the aircraft master and the Primary master to adequately power the avionics.

My question is, is there a more efficient alternative to the diode array that I originally installed?

Thanks.

This might work better:

He says it's 0.5 volts drop at 30 amps.

Try one of these:

Power Schottky Rectifier:
MFG: IXYS
Part: DSS 2x121-0045B

Should give you back .7-.9 volts

Just replace your diode pack with above.
