PFC MicroS Design Guide
PFC MicroS “Quick Install” Instructions
(For mechanical drawings, see page 8)
Mounting the PFC MicroS
* The PFC MicroS can be mounted on either of three sides.
* Use #8-32 or 4mm mounting screws. Maximum penetration should not exceed
0.25 in. (6mm) on the side and 0.125 in. (3mm) on the bottom.
* Maintain 2" (5,1cm) clearance at both ends of power supply for airflow.
Input Connections
Input Power MBJI
* Input AC power is applied to connector MBJI.
* Maximum torque is 5 in.lb.
* A fuse or circuit breaker in the input line is necessary for safety requirements (10A).
* Molex mating receptable 39-01-4051, terminals 39-00-0089, crimp tool 11-01-0199.
Output Connections
Power Connections
Installing bus bars on output studs (when full size and half size modules used):
* The right stud is Positive and the left stud is the Return on single output cards.
* Remove the nut and place ring lug over output stud.
* Replace and tighten the nut to a torque of 10 inch pounds.
Do Not Over-Tighten Nuts.
Installing power connectors with 16 pin Molex connectors (when quarter size
modules used):
* S1J1-7 and S1J1-15 are Positive for output #1, while pins S1J1-8 and S1J1- 16
are the Return. S1J1-4 and S1J1-12 are Positive for output #2, while pins
S1J1-5 and S1J1- 13 are the Return. S1J1-1 and S1J1-9 are Positive for out-
put # 3, while pins S1J1-2, and S1J1-10 are the Returns.
* For this 16 pin housing, use Molex mating receptacle #39-01-2160 with #39-
00-0039 terminals.
* Attach 18-24 AWG stranded wire using Molex tool #11-01-0197.
See page 10 for diagrams of output connections.
Sense Connections
Sense Connections on output connection(s) with studs:
* The PFC MicroS is shipped with Auto Sense installed (For more information
on Autosense, refer to page 12)
* For Remote Sense, connect Remote Sense wires to the Trim Connector (S1J2
connector for single outputs, and S1J1/J3 connector for dual outputs).
* Pin 2 is the +Sense and Pin 3 is the -Sense.
* 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 point where regulation is desired.
* Verify that sense lines are not cross-connected.
Note: Remote Sense is not available for triple output configurations.
Trim Connections
Trim Connections on output connection(s) with studs:
* Pin 1 on the Trim connector provides Trim access. (S1J2 connector for
single outputs, and S1J1/J3 connector for dual outputs).
* Use Molex mating receptacle #50-57-9403 with #16-02-0103 terminals.
* Attach 24-30 AWG stranded wire using Molex tool #11-01-0208.
