regulation is desired. Verify that sense lines are not cross-connected.
Sense Connections on output connections with 18 pin Molex connectors:
* The PFC Micro is shipped with Autosense installed (For more information on
Autosense, refer to page 11)
* If Remote Sense is desired, connect Remote Sense wires to sense lines of
Connector S1/S2 J1.
* Connector pin S1/S2 J1- 13 is the +Sense and S1/S2 J1- 15 is the -Sense for
output #1. S1/S2 J1- 4 is the +Sense and S1/S2 J1- 5 is the -Sense for output
#2.
* Use Molex mating receptacle #39-01-2180 with #39-00-0039 terminals.
* Attach 18-24 AWG stranded twisted pair wire using Molex tool #11-01-0197
Note: Remote Sense is NOT available for triple output slots.
