That's correct. My 160 amp alternator is cold rated at 160. At operating
temperature (too hot to touch) it only puts out around 135 or so. The
160 figure is really a marketing figure.
Another fine example of a tinker toy alternator.
Most of the so called marine alternators are just that, tinker toy
alternators.
Define a tinker toy alternator?
Most are cold rated, strictly a marketing gimmick.
Most are rated bath cold and hot.
A true heavy duty alternator is hot rated, not cold.
As are most marine alternators. Both figures are useful.
At least they were when I was involved in their design a long time ago.
Welcome to the 21st century.
If you want to see some real alternators, look at Leece-Neville.
Do they make one suitable for marine applications? If so, then I will
take a look at them.
A 200 amp alternator is truly a hot rated 200 amp alternator, not some toy
that has to be derated if you read the fine print.
Doesn;t matter as long as on understands what is going on.
Of course, it will cost more, there ain't no free lunch.
Cost doesn;t amtter when it is a boat.
