Switching power supply start-up time, hold time, long time, fall time, which standard
Rise time: the output voltage from 10% to 90% of the time, the rise time is generally less than 50ms, too long may cause the machine malfunction.
Hold time: After the input power is turned off, the output voltage is maintained with 90% of the specification time.
Switching power supply start time is the power switch to close to the output voltage of 90% of the Uo up to that time;
Hold time is the power switch off, to the output voltage dropped to 90% of the Uo period of time;
Rise time is the power supply output voltage from 10% Uo up to 90% of the Uo period of time;
The falling time is the time that the output voltage of the power supply drops from 90% of Uo to 10% of Uo.
Start time: that is, since the input power input to the output voltage reaches 90% of the specification time, from the boot to the machine to work
time.
