8.2 Electrical Characteristics
8.2.1 Power Supply
Table 13: 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.
2.1 A Peak at 5.5 V.
Note
:
The M1306B is permanently powered once the power supply is connected. The
following table describes the consequences of over-voltage and under-voltage with
the Fastrack M1306B.
Warning:
All the input voltages specification described in this chapter are at the M1306B input.
While powering the M1306B, take into account the input drop caused by the power
cable. With the delivered cable, this input drop is around 700 mV at 5.5 V and 220
mV at 32V.
Table 14: Effects of power supply defect
If the voltage then
falls below 5.5 V, the GSM communication is not guaranteed.
is over 32 V
(Transient peaks),
the M1306B guarantees its own protection.
isover 32 V
(continuous overvoltage)
the protection of the M1306B is done by the
fuse (the supply voltage is disconnected).
The fuse is a 800 mA / 250 V FAST-ACTING 5*20mm. See Chapter 10 for
recommended references.
The following table provides information on power consumption of the Fastrack
M1306B, assuming an operating temperature of +25 °C and using a 3 V SIM card.
