Reference Value
Item Value Definition
Reliability (MTBF) 135,000 hours 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
10-/25-/50 (5, 12 V)-/100 (5,
12, 15 V)-/150-W Models
8 yrs. Min.
The life expectancy indicates average operating hours under
the ambient temperature of 40 ° C and a load rate of 50%.

300-/600-W Models
10 yrs. Min.
Normally this is determined by the life expectancy of the
built-in aluminum electrolytic capacitor .
