Overview
With a power density greater than 7W/in
3
,
Westcor's FlatPAC-EN is an ultra low profile,
compact, EN compliant autoranging AC-DC
switcher. It is capable of providing up to 500
Watts from up to 4 isolated outputs.
For maximum versatility and flexibility, the
FlatPAC-EN can be configured with standard
Vicor DC-DC converter modules - full, half
and quarter brick sizes. These modules cover
the entire range of outputs from 1 to 100Vdc
and 25 to 500 Watts, as well as an array of
non-standard voltages. The optimum FlatPAC-
EN solution can be factory configured based on
your exact voltage and power requirements.
For conducted EMI, the FlatPAC-EN conforms
with FCC Class A and B, and EN 55022,
Class A and B. Some configurations may require
our optional external in-line filter to meet
EN 55022 Class B. Further, besides meeting
the cULus, TV and CE safety agency
approvals, the FlatPAC-EN complies with
harmonic current limits per EN 61000-3-2,
Electrical Fast Transient/Burst per EN 61000-4-4
and Surge Immunity per EN 61000-4-5. For
harmonic current compliance to EN 61000-3-2,
do not exceed input current of 3.33 A rms at
230Vac, 50 Hz.

Autosense Feature
*
This is a new feature implemented in all converter slots in the FlatPAC-EN.
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 outputs utilizing Maxi or Mini size converters.

FlatPAC-EN Configurations
Vicor's DCDC converter modules are used to populate the
FlatPAC-EN. There are several configurations available
depending on module size, power limitation and location
of the MiniHAM*. The two-output FlatPAC-EN contains
1 Maxi and 1 Mini. The three-output FlatPAC-EN contains 3
Minis. The four output FlatPAC-EN contains 1 Mini and 3
Micros. See below.
Note: The FlatPAC-EN is limited to a maximum output power of 500W regardless of the module capability. For example, if three
Mini modules are used, the maximum output power for the FlatPAC-EN is still 500W irrespective of the maximum output power of
the modules. For EN 61000-3-2 harmonic current compliance, input current of 3.33 A rms should not be exceeded.
* The MiniHAM is a passive harmonic attenuator specifically designed for EN compliance. Unlike active PFC solutions, the
MiniHAM generates no EMI, greatly simplifying and reducing system noise filtering requirements. It is also considerably smaller
and more efficient than active alternatives and improves the unit's MTBF. It will provide harmonic current compliance at 230Vac
input at up to 425W of output power.
** For a single output configuration either M1 or M2 is used.
