2.4 Function
The generator, which is powered by the motor of the vehicle, supplies a
variable three-phase-voltage with a speed-dependant frequency. The
electronic module adjusts a stable output voltage of the generator via
the field winding.
In the electronic units MB7500-110AC, this three-phase alternating
current is firstly rectified, and then, in an IGBT-module, transformed
into a one-phase alternating current of 110V 50Hz. At the output
terminal of the electronic module the sinusoidal- and the EMC-filter
ensure a sinusoidal voltage with low harmonic components.
The operating panel supplies the system with an auxiliary voltage from
the vehicle’s 12V or 24V electric distribution system.
The 110V power circuit has no low-resistance conductive connection to
the 12 / 24V electric distribution system of the vehicle (safe
separation).
The operator panel MB6001F-110 is connected to the electronic
module, via a shielded 12-strand control line. The operator panel
indicates current and voltage.
Four signal LEDs give information on irregularities or hazards.
The master button I/O turns the system on or off.
The green LED I/O signals, that the system is operational.
