8.2 Electrical characteristics
8.2.1 Power supply
Table: Electrical characteristics without battery option
Power supply range
- 5.5V à 32V DC (GSM ou DCS ou GPRS)
Average consumption
- GSM 900 MH : 109 mA @ 12V in communication
- GSM 1800 MHz : 97 mA @ 12V in communication
- Idle mode
: 18 mA @ 12V
Once the power supply is connected, the modem is permanently consuming.
The following table describes the consequences of over-voltage or insufficient voltage on the modem.
Table: Effects of a power supply defect
Then :
▪
Voltage falls below 5.5V
▪
The functioning and the GSM 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 short-circuited by an internal surge
suppressor ).
The following tables show the modem consumption without the RS232 connected.
