S8VK-G
Therefore, connect bypass diodes (D1, D2) as shown in the
following figure.
If the list of models that support series connection of outputs says
that an external diode is not required, an external diode is also not
required for positive/negative outputs.

 Use the following information as a guide to the diode type, dialectic
strength, and current.
 Type: Schottky barrier diode
 Dielectric strength (VRRM): Twice the rated Power Supply output
voltage or higher
 Forward current (IF): Twice the rated Power Supply output
current or higher
Backup Operation
Backup operation can be performed with S8VK-R.
Refer to the S8VK-R Datasheet for detail.
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, 180-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.
