NOTES
1. Maximum difference between the voltage magnitudes of outputs
2 & 3 for triples: 3 & 4 for quads.
2. All models except triples have provision for output voltage
adjustment. See connection table and external output trimming
information.
3. No minimum load required for operation
4. Any output.
5. REMOTE SENSE is provided on all singles, and on output #1 of
duals and triples. It will compensate for up to 1V drop between
converter and load. If remote sense is not being used, the
+Sense should be connected to its corresponding +Output, and
likewise the -Sence should be connected to its
corresponding-Output.
6. 5V output clamped at 6.8V,12V or 15V outputs clamped at 18V.
7. OUTPUT ISOLATION ON DUALS: The two outputs are isolated,
and can be referenced as either positive or negative, No load
sharing is possible.
