7. The life expectancy
The life expectancy of the power supply is as follows.
The life of the power supply depends on the life of the built­in aluminum electrolytic capacitor.
The life expectancy is not a guaranteed value, please consider as a reference.
Please do not use the product which passed over the life expectancy.
There is a risk of unexpected output shutdown and specifications may not be satisfied.
Please contact us for maintenance or exchange the product which passed over the life expectancy.
The life expectancy of power supply is calculated in condition of rated input voltage and 24­hour continuous
operation.
Load (%) is percent of maximum output power or maximum output current, do not exceed its derating of
maximum load.
