Output Voltage External Control (PV)
Output voltage external control function is available. Output
voltage can be varied by applying an external voltage (1–6V) to
"PV" terminal and "COM" terminal. Please consider the follow-
ing characteristics.

Auxiliary Supply

Auxiliary supply (12V, 0.1A max) is provided to ease customer
application. Aux voltage is functionally isolated from all other
signal terminals and output terminals, and it is always available
as long as input power in the specifi ed voltage range is present.
