Overview

The PFC MicroS, PFC Micro and PFC Mini are
members of the new low profile, high-density
LoPAC series of power factor corrected AC-DC
power supplies. Available as a one, two or three
slot package, respectively, each LoPAC slot
can be configured with standard Vicor DC-DC
converter modules enabling up to six user
specifiable isolated outputs in a package only

1.75'' (44.5mm) high with a power density

of 11W/in3.

For maximum versatility and flexibility, the
LoPAC can be configured with Vicor 1st
Generation VI-26x (full brick), VI-J6x (half
brick) or 2nd Generation V375 Series full, half
and quarter brick modules. These modules
cover the entire range of outputs from 1 to
100Vdc and 25 to 600 Watts. We will factory
configure the optimum solution based on your
exact requirements.

All units comply with FCC Class Aand certain
configurations meet FCC & EN55022 Class B
for conducted EMI. Harmonic current limits
per EN61000-3-2 and Surge Immunity per
IEC61000-4-5 Level 3, in addition to a wide
variety of safety agency approvals, further
enhance the LoPAC flexibility.

Autosense Feature

*

This is a new feature implemented in all converter slots in the
LoPAC family. If remote sense connections are not needed or
are inadvertently not made, no local sense connections are
necessary. Simply connect the output(s) to the load and the

converter(s) will automatically operate in the local sense mode.
If remote sense connections are made, the unit will operate in
remote sense mode.

LoPAC Slot Configurations

The DC-DC converter modules are used to populate each
LoPAC converter slot. Each slot can be configured in different
ways depending on module sizes and power limitations.

The following table summarizes the available slot
configurations for each of the three LoPAC packages.

DC Output Selections

The versatility of the LoPAC series is due, in large part, to the
wide array of Vicor modules available to be configured into the
different package formats. Slots can be populated with 1st or
2nd Generation modules in full, half or quarter brick sizes.
Vicor’s full VI-26x, VI-J6x and V375 standard product

matrices are available to choose from. In addition, the full range
of non-standard voltages and powers from 1 to 100Vdc and 10
to 600W is also available for inclusion. The table below is just a
sampling of some of the most popular standard outputs that can
be configured into LoPAC slots.
