Characteristic curves for alternator type AAK3570 28V
35A (for 24 V outfits)
The curves have been detected with electronic voltage regulator
after thermal stabilization at 23 ± 5°C;test voltage 13 V.
I = Current in Ampere
Note: The alternator rpm is equal to the rpm shown in the table
Characteristic voltage curve for regulator type AER 1528
The electronic voltage regulator is built into the alternator.
The curve changes depending on temperature.
A = Max. voltage curve
B = Min. voltage curve
Workshop Manual LDW CHD _ cod.
The alternator has a W terminal for a speed indicator.
multiplied by 1000.
Ratio between engine/alternator rpm = 1:1.8.
