2.9 OPTIONS
2.9.1 LIGHTING, WIPERS AND HEATER
2.9.1.1 VOLTAGE CONVERTER
The options such as heater, lighting or wipers operate with a power supply of 12 V. The battery voltage of
80 V is reduced to this value by the voltage converter.
The voltage converter functions according to the chopper principle. This means that the battery voltage is
converted into a 20 kHz rectangular voltage. This rectangular voltage is reduced by a transformer and
subsequently rectified.
The input side is galvanically separated from the output side and is not connected to ground. The output is
not regulated, i.e. the output voltage varies with input voltage and load. The output voltage is indicated by
a light emitting diode. The output fuse makes the converter short-proof. There is a false pole protection at
the input side of the converter.
CAUTION: The maximum power of the voltage converter is 200 W. If the required power is higher, a second
voltage converter must be installed. This voltage converter must not be connected in parallel
to the existing one. The two voltage converters must be separated on the secondary side at the
fuse socket.
Maximum load for a voltage converter (200 Watt) corresponds to
- 3 working lights with 55 W each
or
- 2 working lights with 55 W each and front and rear windscreen wipers
or
- truck lighting and traffic options
