Parameter Specification
Shock and
vibration test
EN 600068-2-6 n Mechanical test of resistance to vibration
n 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.
EN 600068-2-27 n Mechanical test of shock resistance
n Test conditions: Shock, 3-axis test, 11 ms at 15 g
n 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).
Power consumption n 60 W … 200 W, temperature‑controlled
n From car battery
Mounting positions n Horizontal position (with shock mounts below)
n Vertical position
n Not allowed: upside down position
Grounding Circuit ground is connected to ground of the
backplane, which is isolated from car battery ground.
Physical size Refer to AutoBox Dimension Drawings on page 277.
Weight (without boards) Approx. 5.3 kg (11.7 lbs)
Ambient temperature n 0 … 55 °C (32 … 131 °F)
n –10 … 55° C (14 … 131 °F) with optional heater
