PFC Micro Design Guide
PFC Micro “Quick Install” Instructions
(For mechanical drawings, see page 8)
Mounting the PFC Micro
* The PFC Micro can be mounted on either of three sides.
* Use #8-32 or 4mm mounting screws. Maximum penetration should not exceed
0.25in. (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 MBJ1
* Input AC power is applied to connector MBJ1.
* Maximum torque is 5 in.lbs
* A fuse or circuit breaker in the input line is necessary for safety requirements (10A).
* Molex mating receptacle 39-01-4051, terminals 39-00-0090, crimp tool Molex
# 11-01-0199.
Output Connections
Note: Outputs with current molex connectors are limited to 9A/pin (27A per output). A
PFC Micro with DIFFERENT Molex connectors capable of 40A is available. Contact
factory.
Power Connections
Installing bus bars on output studs (when full size module 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 18 pin Molex connectors (when half size mod-
ules used):
* S1/S2 J1-7, S1/S2 J1-8 and S1/S2 J1-16 are Positive for output #1, while pins
S1/S2 J1-9, S1/S2 J1-17 and S1/S2 J1-18 are the Returns. S1/S2 J1-1, S1/S2
J1-10 and S1/S2 J1-11 are Positive for output #2, while pins S1/S2 J1-2, S1/S2
J1-3 and S1/S2 J1- 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.
Installing power connectors with 16 pin Molex connectors (when quarter size
modules used):
* S1/S2 J1-7 and S1/S2 J1- 15 are Positive for output #1, while pins S1/S2 J1-8
and S1/S2 J1- 16 are the Return. S1/S2 J1-4 and S1/S2 J1-12 are Positive for
output #2, while pins S1/S2 J1-5 and S1/S2 J1- 13 are the Return. S1/S2 J1-1
and S1/S2 J1-9 are Positive for output # 3, while pins S1/S2 J1-2, and S1/S2
J1-10 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.
Sense Connections
Sense Connections on output connections with studs:
* The PFC Micro is shipped with Autosense installed (For more information on
Autosense, refer to page 12)
* For Remote Sense, connect Remote Sense wires to Remote Sense/Trim Pin
Access Connector S1/S2 J2.
* Connector pin S1/S2 J2-2 is the +Sense and S1/S2 J2-3 is the -Sense.
* Use Molex mating receptacle #50-57-9403 with #16-02-0103 terminals.
