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 outputs 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 the Vicor
Applications Engineering Department for assistance with applications that use long cable lengths and
excessive load capacitance.
