Startup time

In power supply equipment, when the input voltage is turned on, a slight response delay occurs in the output voltage due to the characteristics of the circuit. The time it takes for the output voltage to reach 10% is called the delay time. The time it takes for the output voltage to rise from 10% to 90% is called the rise time. The sum of the rise time and the delay time, that is, the time from when the input voltage is turned on until it reaches 90%, is called the startup time, and it serves as one indicator of equipment performance.
