Power Measurements

Multi-Tech Systems, Inc. recommends that you incorporate a 10% buffer into your power source when determining
product load.
Note:
The following notes apply to the following tables.
Tx Pulse: The average peak current during a GSM850 transmission burst period or HSDPA/LTE
connection. The transmission burst duration for GSM850 can vary, depending on what transmission
scheme is being deployed (GPRS Class 8, Class 10, GSM, etc.).
Maximum Power: The continuous current during maximum data rate with the radio transmitter at
maximum power.
Inrush Charge: The input current during power up, or a reset.
