Vicor FlatPAC-EN MI EN Compliant Autoranging Switchers - Manual (Page 8)

Installing power connectors on outputs with 18 pin Molex connectors
(only half and/or quarter bricks used):
• The output M1 slot only accepts a Micro module. J2-7, J2-8, J2-13 and
J2-16 are positive, while pins J2-9, J2-15, J2-17 and J2-18 are the
returns.
• The output M2 slot only accepts a Micro module. J2-1, J2-4, J2-10, J2-
11 are positive, while pins J2-2, J2-3, J2-5 and J2-12 are the returns.
• The output M3 slot only accepts a Micro module. J3-7, J3-8, J3-13
and J3-16 are positive, while pins J3-9, J3-15, J3-17 and J3-18 are the
returns.
• The output M4 slot only accepts either a Mini or a Junior module. J3-1,
J3-10 and J3-11 are positive while pins J3-2, J3-3, and J3-12 are the
returns.
• For this 18 pin housing, use Molex mating receptacle #39-01-2180 with
#39-00-0039 terminals.
• Attach 18-24 AWG stranded wire using Molex tool #11-01-0197
• Note: The molex connectors are limited to 9A/pin (27A per output)
See page 11 for detailed diagrams of output connections.
Sense Connections
The FlatPAC-EN/EN MI is shipped with Autosense installed (For more informa-
tion on Autosense, refer to page 16)
Sense Connections for stud outputs (only full and/or half bricks used):
• For Remote Sense, connect Remote Sense wires to Remote Sense/Trim Pin
Access Connector J1 or J2 for single output and J1/J2 for dual outputs.
* Connector pins J1-2 and J2-2 are the + Senses and J1-3 and J2-3 are
the -Senses.
• Use Molex mating receptacle #50-57-9403 with #16-02-0103 terminals.
• Attach terminals to 24-30 AWG stranded twisted pair wire using Molex tool #
11-01-0208.
• Attach opposite end of sense lines to their respective outputs to point where
regulation is desired. Verify that sense lines are not cross-connected.
Sense Connections on 18 pin molex output connectors (only half bricks used):
• If Remote Sense is desired, connect Remote Sense wires to the sense lines of
Connector J2 for output 1 and J3 for outputs 2 and 3.
* For Output M1, J2- 13 is the +Sense and J2-15 is the -Sense.
* For Output M2, J3-13 is the +Sense and J3-15 is the -Sense.
* For Output M3, J3-4 is the +Sense and J3-5 is the -Sense.
• 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.
Sense Connections on 18 pin output connectors (only half and/or quarter bricks
used):
• If Remote Sense is desired (available only on output M4), connect Remote
Sense wires to sense lines of Connector J3
* Remote Sense is NOT available for Micro modules and hence is not
available on outputs M1, M2 and M3.
* On output M4, J3- 4 is the +Sense and J3-5 is the -Sense.
• 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
