Input voltage refers to the voltage which users provide to power adapter and make power adapter work. Alternative current(AC) and direct current(DC)  are common input.
Input voltage has a range for the power adapter,AC 170Vac-264Vac/90Vac-130Vac/90Vac-240Vac and DC 12VDC-24VDC are common input range.
This parameter guarante power adapter can be used in the user's device.

Input frequency is the power adapter input AC frequency.47Hz-63Hz is common range.
This parameter guarrantee the power adapter can meet  the grid requirements of user's countries and regions.
