Power Supply
-
Input Voltage Range: 10.6 – 32 VDC
-
Consumption:
-
Tx On (i.e. IP connection active and transmitting): 300 mA/12 VDC,
150 mA/24 VDC, with maximum transmitter power -
GPS*: +45 mA/12 VDC, +25 mA/24 VDC
-
Idle: 70mA/12 VDC, 35 mA/24 VDC
-
Sleep mode: 50 mA/12 VDC, 25 mA/24 VDC
-
Power Off: <0.1 mA
-
* Power consumption increase caused by GPS receiver. E.g. Idle power consumption with GPS active: 70 mAh (Idle) + 45 mAh (GPS) = 115 mAh at 12 VDC.
