2.6.4 VOLTAGE CONVERTER
The voltage converter (DC-DC converter) converts the 80 V battery voltage into a constant 24 V direct current
voltage. This voltage is used to power the electronic controls, fan and steering axle proximity switches.
The output voltage of the converter is not separated galvanically from the input voltage. The maximum output
current at 24 Volt is 3.3 Ampere (equals 80 Watt).
The green LED on the voltage converter is illuminated when the converter supplies the 24 V power output.
The converter is short-proof.
