2.6 Power Supply
2.6.1 Supply voltage requirements
The DC power supply must be connected to the POWER input:
• Input voltage range
9 - 24V DC
• Nominal Voltage 12V DC
NOTE: these are the absolute maximum ratings – for use e.g. in trucks with 24V nominal voltage,
an additional DC/DC converter has to be used.
• Power Supply current rating:
min. 1,2A @12V
• Power Supply ripple:
max. 120mV
• Input current in idle mode:
8mA @ 12V
• Input average current in communication mode:
110mA @ 12V
NOTE: In case that power supply equipment is to be ordered, its conformity needs to be verified
with the mains supply voltage, frequency, connector type and other national requirements (e.g.
certifications) in the countries of its use.
2.6.2 Power Connector
The power connector is on the left side of the terminal is Molex 4-pin connector (part no.:43045-
0400 male)
