200amp alt question.... first of many to come

[coachgeo]

going to install hummer 200amp alt in my LMTV (200AMP 14/28 DUAL VOLTAGE; Niehoff ; N1225-1 1244710).

general question... what is the amperage output split? 100 amp for each 14 and 28 (50/50 split)?? orrr varies on demand with max 50/50 or is it 60/40 orrr is amp output not limited to either side and whatever has highest draw just leaves the remaining potential left for the other ???? or am I totally confudled and looking at this entirely wrong.



PS- yes searched.. did not find answer but would be happy to search more if anyone can throw out potential keywords to search by and I'll try again.

200 amps of 24v and 50 amps of 12V is what the HMMWV 200 amp alt will put out to my understanding.

see page 2 description of operation in the N1225 TG https://www.ceniehoff.com/Documents/Ctrl_Hyperlink/TG0017B_uid882013200562.pdf
so 200 28v no 14v load and less than 200 28v with 50A of 14v(basically the 14v robs the 28V side)
as a note the 12v/14v taps the come out of the regulator their made to handle 50 amps but can output a little more BUT they will overheat if you put too much load on them. so make sure you don't have too many 12v/14v loads on there

Did you ended up installing the 200A alternator ? I'm on the same page as you looking to use it to charge my LIFEPO4 bank while driving as a backup for days with no sun.
