Title: Power supply instable
Post by: HansNordsiek on August 30, 2017, 05:06:44 pm

Hello all,


My Pilotaware unit works OK when on battery only. When the alternator kicks in and other power users come on line, the Pilotaware stops.  Must be voltage variations. I do not want a separate battery for that with the hassle of needing to recharge that between flights. Just a smart voltage stabilizer would do the trick. Any suggestions?  Hans

This is very interesting, I think this is what a number of users have probably been seeing in some electrical installations.

The argument usually goes - it works fine for my iPad, but of course the power from your aircraft is simply topping up the iPad battery, in the case of a direct power feed, this is more critical

thanks for hilighting this

Thx
Lee

Fitting a big  reservoir capacitor and diode before the cigarette lighter may absorb the noise spikes? Needs investigating though.
