dSPACE DS1103 User Manual

The DC–DC converter built into the AutoBox/Tandem-AutoBox lets
you operate a dSPACE system connected to a car battery. Due to the
high currents involved, special care must be taken when connecting
the AutoBox/Tandem-AutoBox power supply to the car. Wires with
high cross-section (6 mm
2
minimum) are mandatory to avoid poor
performance of the power supply and excessive heating of the wires.
