24-61-01 Alternator-Regulator Adjustment E4A-91-200-000
There is no regulator adjustment (e.g.: by potentiometer) required to establish a stable voltage
regulation.
24-61-02 Paralleling for twin engine system E4A-91-200-000
A current-regulator is implemented, which enables the adjustment of the load balancing in twin-
engine applications with high accuracy and fault-tolerance against single faults at the load-balancing
adjustment structure. The set point of this current regulator is generated dynamically as averaged
load current of both alternators.
The set point of one voltage regulator in the system is modified continuously to compensate static and
dynamic asymmetries of the system.
