1 About PowerBox PBX 190
The Bosch PowerBox PBX 190 takes the whole Power Control Module concept much fur-
ther than existing modules. It provides an effective and inspired alternative to conven-
tional relays, circuit breakers, fuses and wires that can so often be a tangle of complexity
and untidiness around a typical racing car’s power junction box.
Bosch PowerBox PBX 190 is a compact and light weight module, measuring 245 x 183 x 37
mm (including connectors).
Bosch PowerBox PBX 190 has 52 outputs. All outputs are protected against reversed bat-
tery polarity. Current draw can be measured on all outputs from 0 mA.
Any of these channels can be controlled by various types and combinations of inputs.
You’ll find more information at Technical Specifications [
}
36].
Instead of using a conventional control program, Bosch PowerBox PBX 190 benefits from
a 667 MHz dual Core Processor and a multitasking operating system, allowing simultan-
eous executions of operations.
Please note that the maximum recommended current draw per channel is limited by the
connector contacts (wiring loom side) - not by Bosch PowerBox PBX 190s driver stages.
We have rated the individual channel’s current draw in relation to the connector manufac-
turer’s specifications.
Bosch PowerBox PBX 190 is programmed to shut overloaded channels down if the current
draw or internal junction temperatures exceed pre-set levels.
A smart algorithm allows automatically turning-on of loads with a high inrush current.
The current draws and channel status can be logged internally and exported via one of
the three available CAN bus.
WARNING
Please note that the PowerBox PBX 190 is not intended to be used to
control safety-critical systems on a vehicle, such as ABS braking,
power steering, etc..
Bosch Motorsport shall not be responsible for any incidental or consequential damages or
injuries that may occur if the unit is used to control these, or similar, safety-critical sys-
tems.
