Characteristic curves for alternator type Iskra, AAK3139
14V 80A
The curves have been detected with electronic voltage regulator
after thermal stabilization at23 ± 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
