PFC Micro Design Guide
Interface Connections
Chassis Input Power Terminals (MBJ1)
Input AC power is applied through connector MBJ1 using Molex mating connector 39-01-4051. Use 16 AWG
wire with Molex Socket Pin 39-00-0090 and Crimp Tool 11-01-0199.
A fault clearing device, such as a fuse or circuit breaker, with a maximum 10A rating at the power supply input is
required for safety agency compliance. It should be sized to handle the start-up inrush current of 8.5A peak at 115
Vac and 17A peak at 230 Vac.
Output Power Connections
There are three types of output power terminals available in the PFC Micro. Each slot has one of the following
configurations: 10-32 plated steel bolts from outputs using full size converters, an 18 pin Molex connector for out-
puts using half size converters and a 16 pin Molex connector for outputs using quarter size converters. Note: The
Molex connectors are limited to 9A/pin (27A/output)). The positive polarity of the single output termination is the
right bolt when viewed from the output end. Each power output is isolated, so outputs of positive or negative
polarity can be configured through proper selection of the output reference terminal.
In order to minimize parasitic cable inductance and reduce EMI, the output power cables should be routed in close
proximity to one another, and large current loops should be avoided. To avoid excessive voltage drop, do not
undersize power cables, especially for high current outputs. Do not bulk input AC wires with the output wires
because this can couple output noise into the input wires which can increase EMI. Excessive cable inductance
coupled with large capacitive loading can introduce instability in switching power supplies. This problem can be
avoided with proper system design. Consult Vicor’s Applications Engineering Department for assistance with
applications that use long cable lengths and excessive load capacitance.
