Input frequency

In power circuits and similar systems, it refers to the frequency of the AC voltage applied to the input terminal. The input frequency is a crucial factor in determining the output when the power circuit includes components such as coils and capacitors. Therefore, it is necessary to apply a voltage with a frequency that falls within the rated range of the power circuit. If the frequency of the input voltage deviates from the specified value, it may cause malfunctions or failures in the power circuit or the load, so caution is required. Furthermore, in addition to the fundamental sine wave, the presence of high-frequency noise components may also lead to malfunctions or failures, requiring additional attention.
