Input dip tolerance

In power supply circuits and similar equipment, this value indicates the limit at which the output voltage can maintain voltage regulation accuracy when the input commercial power supply momentarily drops due to external surges or other causes. It is defined by two factors: the lower limit of the input voltage at which constant voltage can be maintained, and the maximum allowable duration of the voltage drop. It is one of the indicators of performance for power supply circuits and similar devices. Regarding input dip tolerance, the lower the minimum limit of the input voltage and the longer the allowable voltage drop duration, the greater the resistance to momentary voltage drops.
