[caution]
Remote switch is
connected to–output,
so do not connect to
the other remote switch
simultaneously.
[caution]
Please keep all the settings
of voltage the same. Output
current will be the summation
of each current.
And, please keep OVP level of
power supply maximum to
prevent any damage.
[caution]
Total output voltage is to be
up to 250V. Therefore for
models with output voltage
of over 250V, series operation
cannot be conducted.
Output current is to be the
smallest current of those.
Additionally, the remote
switch is connected to
–output, so do not connect
to the other remote switch
simultaneously.

It is isolated by optical communication. It makes it possible to prevent
malfunction caused by transient phenomenon such as surge, lightning,
induction, and external noise due to perfectly isolated by optical fiber.
