3.3 Electrical characteristics
3.3.1 Power supply
Table 1:
Electrical characteristics
5 V to 32 V DC (GSM or DCS).
Operating Voltage
ranges
5.5 V to 32 V DC (GPRS Class 10).
Maximum current
480 mA Average at 5.5V.
1.7 A Peak at 5V.
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 2:
Effects of power supply defect
If the voltage :
Then:
falls below 5V
The GSM communication is not guaranteed.
falls below 5.5V
The GPRS Class 10 is not guaranteed.
Voltage over 32V
(Transient peaks)
The modem guarantees its own protection.
Voltage over 32V
(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.
