S8VK-WA
<Backup Operation>
Backup operation is possible if you use two Power Supplies of the
same model.
Even if one Power Supply fails, operation can be continued with the
other Power Supply.
Make sure that the maximum load does not exceed the capacity of
one Power Supply.
Use the S8VK-R or connect external diodes.
For backup operation with 240-W Power Supplies, use the S8VK-
R20.
