1
7 - 21 VDC on units with serial numbers from 15020000 to 15029999.
Make sure all devices connected to the i50’s
VOUT lines (especially via serial ports) can handle the supply voltage.
2
Internal fuses are slow acting. Some over-voltage conditions may cause permanent damage.
3
Includes power for typical active GPS antenna.
4
Average TX power shown. Instantaneous peak cellular or satellite modem power usage can reach 12 W.
5
Power usage will increase when external I/O, VOUT, or serial lines are connected.
6
Protection against 2J pulse. Larger pulses or extended over-voltage conditions may cause permanent damage.
7
Ublox modem used in version 3.2 boards. These units can be distinguished by the externally accessible SIM card.
