2.4. Current DC Power Consumption
The following table lists the current consumption of the AirPrime HL8518, HL8528 and HL8529
modules at different conditions.
Note:
The following data is under the setup recommended in section 3.5 Power Supply Design.
The USB is disconnected for the lowest current consumption.
Typical values are measured at ambient temperature, and maximum values are measured over the
entire operating temperature range. (The measurements are done with a CMU200 and with a 50
Ω
load.) For a description of input voltage requirements, see section 2.1 Power Supply.
