Definition
Reliability (MTBF)
135,000 hrs min.
MTBF stands for Mean Time Between Failures, which is calculated according to the
probability of accidental device failures, and indicates reliability of devices.
Therefore, it does not necessarily represent a life of the product.
Life expectancy
8 yrs. min.
The life expectancy indicates average operating hours under the ambient
temperature of 40
°
C and a load rate of 50%. Normally this is determined by the life
expectancy of the built-in aluminum electrolytic capacitor.

Installation A
Note: When using the 7.5-W single-output
models within the input voltage range
between 90 and 110 VDC, the load
rate will become 90% or less.
When using the 90-W model at an
ambient temperature exceeding
25
°
C, the load rate will become 90%
or less.
