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).
