It senses the voltage on the output wires and controls a ac-dc type switch mode power supply to produce the voltage it is set for (it can be changed) on the output. I have heard that the newer air marines can also do multi stage charging.

I learned what I know from many sources and also from being a bit familiar with similar tech for other applications. > Do any of the manufacturers use adjustable pitched props. > Yes, that is a common thing to do. Again, it is problamtical. The Air Marine uses a prop that flexes and changes its pitch in higher winds, even this approach is not perfect as if that is the primary means of high blade speed regulation, a lot of noise can be produced! Now newer models use electronic blade braking as well to greatly reduce blade noise in high winds. -Ken > _______________________________________________ Liveaboard mailing list [email protected] To adjust your membership settings over the web http://www.liveaboardnow.org/mailman/listinfo/liveaboard To subscribe send an email to [EMAIL PROTECTED] To unsubscribe send an email to [EMAIL PROTECTED] The archives are at http://www.liveaboardnow.org/pipermail/liveaboard/ To search the archives http://www.mail-archive.com/[email protected] The Mailman Users Guide can be found here http://www.gnu.org/software/mailman/mailman-member/index.html
