2. Technical Specifications
2.1.
Power Supply
The modem is supplied by an external DC voltage, DC-IN, with a voltage range of
+4.75V to +32V.
The main regulation is made with an internal DC/DC converter in order to supply all
the internal functions with a DC voltage. The correct operation of the modem in
Communication mode is not guaranteed if the input voltage falls below 4.75V.
Refer to the following table for the modem's operating voltage range and maximum
current.

Maximum Current (Typical)
The modem is permanently powered once the power supply is connected. In the
case of Alarm mode (Low Power mode), the user can set the modem "Turn-on" time.
Refer to section 4.1 Alarm Mode for more information.
Caution:
The minimum input voltage specified here is the modem input. Be mindful of the input voltage
decrease caused by the power cable. When using the optional 6-wire cable accessory, this input
drop is at around 800mV at 4.75V and 220mV at 32V (EDGE 4TX).
The modem is designed for use with the original power cable, and the fuse that came with the
original cable is a 2A/250V Slow Break fuse 5.2mm*20mm.
