SCHOTTKY DIODES
Posted: Tue Apr 19, 2005 5:32 pm
Hi,<p>Looking to Schottky diodes, I think, for split charging system on a barge. Main engine alt output is 24V 50A, and I then plan to use a advanced alternator controller which will tweak the alt to make it effective a 4 stage battery charger. Forward voltage is not really an issue as the controller senses battery voltage, but I guess low voltage drop would still be beneficial to reduce strain on alternator. 60A diodes would probably do. <p>Perhaps a diodes like this:<p>http://uk.farnell.com/jsp/endecaSearch/ ... 7449&N=401<p>
The next problem is that the engine battery is a sealed unit, so cannot tolerate the higher voltage that the lead acid battery will take -
actually 12 x 2v 920Ah C10 cells weighing a total of just under 600kg empty - will take a further 120kg of acid to fill them. <p>
So also looking for a single pole voltage sensitive relay that will switch off the feed to the engine battery at the appropriate voltage -
approx 28v I think, letting the domestic battery to rise to 31v when
equalising. <p>
