Switching power supply generally how long the aging time is reasonable?
If you do not often overload, overpressure, humidity is too high, the ambient temperature up and down 30 degrees Celsius under the premise; switching power supply is often used, 3 to 5 years or more normal. Such as a long time to put it 1 to 3 years or so aging (electrolytic capacitor placed too long, the electrolyte will become solidification lead to capacitance degradation). This question involves a lot of things, not very good to determine the length of time.
See how you use it for long term load with high temperature.
Aging conditions: Ambient temperature 35 degrees Celsius.
Aging load: 80% of total power.
Time requirements a little higher, 8 hours. Requires a low 4 hours on it.
And some companies produce low-power power is not aging.
