dSPACE DS1103, Hardware Installation And Configuration Manual

Page: 288 / 302

Parameter Specification
Power supply Remote control Overvoltage protected remote on/off input. The remote
voltage should not exceed the supply voltage.
Overvoltage protection of the remote pin is also 100 V.
If you connect the remote pin to the car battery
directly, the AutoBox will always be turned on, and the
car battery will then soon be exhausted if the engine is
not running. A switch is therefore highly
recommended.

The input resistance also protects the remote input if
the remote signal is switched on while the supply
voltage is missing due to a blown fuse, for example.
Remote on voltage > 4 V
Remote off voltage < 1 V

Test conditions: Sinusoidal vibration, 3-axis test,
5 … 2000 Hz, up to 9 g, 30 minutes per axis
n
During the test AutoBox continuously executed a
program, including I/O without any failures.

During the test AutoBox continuously executed a
program, including I/O without any failures.
Heater (optional) Operating principle The heater is a PTC thermistor (PTC = positive
temperature coefficient). It regulates the heat output
power itself, depending on the temperature of the air
flow from the upstreamed fan:
n
Low temperature -> high current -> high heat
output
n
High temperature -> low current -> low heat output
The PTC is switched on automatically by the AutoBox
power supply, if the temperature of the air flow is
below 0 °C (32 °F).
