Backup Operation
Backup operation is possible if you use two Power Supplies of the
same model.
Even if one Power Supplies 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.
For backup operation, connect the S8VK-R as shown in the figure.
Refer to the S8VK-R datasheet (Catalog No.: T059) for S8VK-R
specifications and the model number for each capacity.
In Case There Is No Output Voltage
The possible cause for no output voltage may be that the overcurrent
or overvoltage protection has operated. The internal protection may
operate if a large amount of surge voltage such as a lightening surge
occurs while turning ON the power supply.
In case there is no output voltage, please check the following points
before contacting us:
•
Checking overload protected status:
Check whether the load is in overload status or is short-circuited.
Remove wires to load when checking.
•
Checking overvoltage or internal protection:
Turn the power supply OFF once, and leave it OFF for at least
3 minutes. Then turn it ON again to see if this clears the condition.
Audible Noise at Power ON
(120-W, 240-W, and 480-W Models)
A harmonic current suppression circuit is built into the Power Supply.
This circuit can create noise when the input is turned ON, but it will
last only until the internal circuits stabilize and does not indicate any
problem in the Product.
