8.2 Electrical characteristics
8.2.1 Power supply
Table 8: Electrical characteristics
Operating Voltage
ranges
5.5 V to 32 V DC (GSM or DCS or GPRS).
Maximum current 480 mA Average at 5.5V.
1.7 A Peak at 5.5 V.
Note: the modem is permanently powered once the power supply is connected.
The following table describes the consequences of overvoltage and undervoltage
with the Fastrack Modem.
Table 9: Effects of power supply defect
If the voltage : Then:
! falls below 5.5 V ! The GSM communication is not guaranteed.
! Voltage over 32 V
(Transient peaks)
! The modem guarantees its own protection.
! Voltage over 32 V
(continuous overvoltage)
! Protection of the modem by the fuse (the
supply voltage is disconnected).
The following table provides information on power consumption of the Fastrack
modem, assuming an operating temperature of +25 °C and using a 3 V SIM
card.
