The Electric Power System.
In the new EPS, the truck-mounted pump is driven in the
conventional way directly via a power take off. A second
power take off is used to drive a new kind of high-power
generator, which supplies electrical energy independently
of the rotational speed to a 600 V DC on-board supply
system in the detachable unit. From this DC supply, the
individual loads are supplied with traditional 400 V AC
through inverters.
The generator starts automatical y when the pump is start-
ed. Independent operation is also possible. With up to 140
kVA, it delivers sufficient energy to supply al the required
electrical equipment in the truck. For the first time, electri-
cal y driven devices can be flexibly supplied with current
in the vehicle and simultaneously pressure proportioning
systems with high output and compressed air foam systems
