Time drift

This represents the relationship between time and output voltage after power is turned on in power supply circuits and similar applications. Evaluation is based on voltage fluctuation from 30 minutes to 8 hours after the power is turned on, under rated input and output conditions. The first 30 minutes are excluded due to initial drift. Typically, the rate of increase in output voltage becomes more gradual over time and eventually stabilizes at a constant value. A shorter time to reach that constant value is preferable for output stability.
