An internally or externally mounted low-pass or band-reject filter at the power supply input which reduces the noise fed into the power supply.
A band-reject or low-pass filter on a power supply's input designed to reduce the level of line noise being introduced to the supply.
Typically an internally located low-pass filter used to remove the unwanted noise generated by a converter from being transmitted to the input wiring.
A power filter placed on the input to a circuit or assembly that attenuates noise introduced from the power bus. The filter designed to reject noise within a frequency band. Typically these are low pass filters, meaning they pass low frequency signals, such as the DC power, and attenuate the higher frequency signal, which consists of mainly noise.
A low-pass or band-reject filter at the input of a power which reduces noise fed to the supply or created by the supply. This filter may be external to the power supply.
A low-pass or band-reject filter used to decrease the noise fed to the supply. Input line filters are located at the input of a power supply and may be external.
An internally or externally mounted low-pass filter or harmonic traps located at the battery charger or power supply input or output to reduce conducted or radiated emissions.
