This chapter describes assembly of the different electrical components of a CloudLink 5G Modem.
6.1 Power Supply
CloudLink 5G Modem supports external power supply and battery connection that connects the
device to Lithium battery pack with a voltage rating of 7.2V (±5%).
a. Humidity: Max 95% rH, non-condensing
b. Peak current during transmission: 0.8A @ 5V
c. Duty cycle (GSM) during communication: 0.577ms every 4.6ms
d. Operating voltage (external power supply): 5V to 15V
e. Dynamic Response and Low Ripple
Figure 6.1 - Power Port for External Power Supply/ Battery Pack
The power port on the CloudLink 5G is common for both external power supply and battery con-
nection. So, either you can connect the external power supply or battery pack to the power port at a
time.
