### Power Supply
14 14
15
-当模块在 LTE 模式下以最大功率发射时，电流峰值瞬间最高可达到 1A，从而导致在 VBAT 上有较大的电压跌落。为保证电压跌落小于 300mV，必须保证外部电源供电能力不小于 1A。
15
+When the module transmits at maximum power in LTE mode, the instantaneous peak current can reach up to 1A, resulting in a large voltage drop on VBAT. To ensure the voltage drop is less than 300mV, the external power supply must be capable of providing at least 1A.
16 16
17
-当电源能够提供 1A 的持续电流时，外部供电电容总容值，建议不小于 200uF；若不能提供 1A 的持续电流，则建议外部电容总容值不小于 600uF，以保证任何时候 VBAT 上电压跌落不超过 300mV。
17
+When the power supply can provide a continuous current of 1A, the total capacitance of the external power supply capacitor is recommended to be no less than 200uF. If a continuous current of 1A cannot be provided, the total capacitance of the external capacitor is recommended to be no less than 600uF to ensure that the voltage drop on VBAT does not exceed 300mV at any time.
