Two phases application for Single phase models
For All Single phase Models, S8VK-G
Basically OMRON single phase power supply can be used on two-
phases of a 3–phase-system when some of conditions satisfy like
below.
1.
The supplying voltage is below the maximum rated input.
OMRON Power supply allows the input voltage equivalent or less
than 240 VAC+10%.
Please confirm the input voltage between two lines if the input
voltage satisfies this condition before connecting.
2.
The external protector is needed on N input line to secure a safety.
N line has no protection of a fuse internally.
An appropriate fuse or circuit breaker should be connected on N
input line like the following.

15 W: 600,000 hrs
30 W: 580,000 hrs
60 W: 590,000 hrs
120 W: 450,000 hrs
240 W: 360,000 hrs
480 W: 230,000 hrs
Definition
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 yrs. Min.
Definition
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.
