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.
