3.12 GENERATOR (S/N 88539 TO PRESENT)
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:
Continuous rating:
6.2 HP
0.6 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 alterna-
tor.
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
This fuse protects the dynamo output; it is located on the
left side of the engine.
Rating: 20ADC
Control Fuse
The control fuse provides power to the engine/generator
controller and the relays for start control, fuel control and
glow plug.
Rating: 15ADC
This fuse is located on the right side of the engine.
