8.2 Electrical characteristics
8.2.1 consumption
Table: Electrical characteristics
Once the power supply is connected, the modem is permanently consuming.
If the battery option is present, prepare the modem for storage or transport phases in order to
limit high discharges of the battery. For that, see the §
The following table describes the consequences of over-voltage or insufficient voltage on the modem.
Table: Effects of a power supply defect
The following tables show the modem consumption without/with the GPS antenna and without the RS232
connected.
The power supply consumption may vary by 5% depending on the temperature range (-20 °C
to +55 °C).
Power supply range
- 6.5V to 32V DC (GSM or DCS or GPRS)
Average consumption
- GSM 900 MHz : 154 mA @ 12V en communication
- GSM 1800 MHz : 146 mA @ 12V en communication
- Mode repos :
20 mA @ 12V (GPS désactivé)
- GPS : 20 mA @ 12V en recherche de position
16 mA @ 12 V en fixe
Then:
▪ Voltage falls below 6.5V
▪ The functioning and the GSM and GPS
communication are not guaranteed.
▪ Voltage above 32V
( Punctual peaks)
▪ The modem guarantees its own protection.
▪ Voltage above 32V
( Continuous over-voltage)
▪ The modem is protected by the fuse
(the modem is put in c.c. via a para surtensor internal
varistance).
