3.1 Intelligent power distribution SCS1000/3000 and
PDUsetup
Especially the system size and high load currents are important within an ever more
demanding vehicle architecture, where space in the vehicle is at a premium. The
SCS1000 and SCS3000 series are extremely compact power distribution systems with
integrated logic. The modules provide considerable functionality combined with high
efficiency in one of the smallest form factors. The SCS1000/3000 are ideal in terms of
their upgradeability for fleet modernisation and projects where space-savings are of
the utmost importance.
The SCS3000 modules are ideal for a centralised system approach. Power distribution
and control functions, such as logical connections, PWM and soft start are combined
in one module. Multiple individual components can be replaced by a single one.
The SCS1000 is the ideal entry-level solution for small and decentralised system
architectures and is the first step to vehicle digitisation.
Besides power distribution, the SCS1000 and SCS3000 provide more transparency
on the load side, by feeding back the current and condition values. Additional safety is
guaranteed by the integral electronic load protection, the enhanced inrush handling, the
current limitation and the soft start functions. The inputs of the SCS modules can be
configured as analogue or digital inputs and are ideal for detecting sensors installed in
the vicinity of the device. Logical links between inputs and outputs can also be realised.
The SCS1000 and SCS3000 modules have comprehensive communication interfaces.
The connection to the vehicle system is made via up to three CAN channels. Via
Ethernet, using a PC, live data from the system can be requested and observed for
diagnostic purposes.
The SCS3000 and SCS1000 modules can be configured via the PDUsetup graphical
programming interface. A comprehensive symbol library and communication settings
guarantee flexibility. In addition, the PDUsetup enables simulation and diagnostic tools.
Fig. 1 shows how the SCS3000 can be integrated into the on-board electrical system.
