4. Technical Specifications
4.1. Power Supply
The Fastrack Xtend is supplied by an external DC voltage, DC-IN, with a voltage range of +4.75V ~
+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 Fastrack Xtend in Communication mode is
not guaranteed if the input voltage falls below 4.75V.
Refer to the following table for the Fastrack Xtend‟s operating voltage range and maximum current.
Table 7. Power Supply Electrical Characteristics
Operating Voltage Range
4.75V to 32V DC, nominal at 13.2V
Maximum Current (Typical)
600mA, average at 4.75V; 3A Peak at 4.75V on FXT002, FXT009
and FXT010
950mA, average at 4.75V; 3.7A Peak at 4.75 on FXT003
The Fastrack Xtend is permanently powered once the power supply is connected. In the case of
Alarm mode (Low Power mode), the user can set the Fastrack Xtend “Turn-on” time. Refer to section
6.1 Alarm Mode for more information.
Caution: The minimum input voltage specified here is the Fastrack Xtend input. Be mindful of the input
voltage decrease caused by the power cable. When using the 6-wire cable accessory that comes
with the Fastrack Xtend package, this input drop is at around 800mV at 4.75V and 220mV at 32V
(EDGE 4TX).
The Fastrack Xtend 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.
