2.4 Electrical Specifications
Input Voltage Range:
+3.6VDC to +5.3VDC or +6.0VDC to +32VDC
Main Input Voltage Ripple:
< 40mV peak-to-peak
Transmit Current (Average):
200mA @ 5VDC
Transmit Current (Peak):
1.5A @ 5VDC
Receive Current (Average):
45mA @ 5VDC
Receive Current (Peak):
195mA @ 5VDC

A @ 5VDC
Power Input Type:
DC power or LiIon battery
NOTE:
The DC power requirement was measured at the 9602-LP multi-interface connector
and not at the DC power supply. Users must take into account voltage drop across the power
supply cable to ensure adequate current provided to the 9602-LP during SBD sessions. If
input voltage does not stay above 3.0VDC during surge or high current demand, the 9602-
LP will reset itself.
NOTE:
The average current drawn during transmission may vary depending on the field-of-
view between the 9602-LP antenna and the Iridium satellite, the type of Iridium antenna
used and the cable loss.
