Generator; Engine; Alternator; Dynamo And Dynamo Voltage Regulator - JLG E450A Service And Maintenance Manual

3.9 GENERATOR

NOTE: Throughout the Generator section, the abbreviation RBS is
used. RBS stands for Rotary Battery System, which is the
generator system.
The engine-driven generator is designed to produce a DC
output directly without the need of a separate rectifier.
Included in the RBS unit is the engine, generator, engine/
generator controller, harness and related components.

Engine

Peak rating: 6.2 HP
Continuous rating: 5.6 HP at 3600 RPM
Refer to the Engine Manual for a complete description of
the engine.

Alternator

The RBS is equipped with a brushless DC output alternator.
The 3-phase AC output of the alternator is full wave recti-
fied and presented to the output terminals.
Output rating: 58.0V at 45A
Voltage regulation and current limiting is provided by the
RBS Engine/Generator Controller.
The rectifier diodes and output current sensor are located
in the alternator endbell.

Dynamo and Dynamo Voltage Regulator

The engine is equipped with a dynamo and dynamo volt-
age regulator.
Dynamo output: 12V
7A DC
Refer to the Engine Manual for a complete description of
the dynamo and dynamo voltage regulator.

Dynamo Output Fuse
