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 A and 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.

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.

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.
*Applies to converter slots utilizing Maxi or Mini size converters.
