Product Description
The FlatPAC family of user-definable offline power supplies provides a complete
power solution that incorporates one, two, or three standard Vicor DC-DC
converters and a front-end subassembly in a modular package. FlatPAC is available
with one, two, or three outputs and total output ratings of 50–600 W. These power
supplies feature an autoranging input, which automatically senses the input line
voltage and sets the power supply’s input range accordingly. FlatPAC’s unique
modular design accommodates over 10,000 different configurations.
FlatPAC power supplies that contain BatMod current source modules instead of
VI-200 converters are indicated by the suffix -BM following the FlatPAC part
number. BatMod converters provide a programmable output current, rather than a
regulated output voltage. Consequently, the output supervisory terminal functions
differ on FlatPACs with BatMod modules.

FlatPAC units are shipped with pins 11-12
and 14-15 connected via jumper plugs
(Vicor P/N 02589) for local sense. For
remote sense, remove these connections
and connect pins 10-12 and 14-16, as
shown in the Output Sense and Trim

All FlatPAC models are available
with a conduction cooled flat plate
instead of the top heat sink. Contact
factory for outline drawings.

Installation and Operation Guidelines
Fusing. The FlatPAC’s internal fuses are not user-replaceable. Please return the
unit to vendor if servicing is necessary.
Grounding. To satisfy IEC 950 Class I grounding requirements, connect a ground
lead to the terminal marked (GND). For one-up FlatPAC models (max. output
200 W), use 1.5 mm2 / #16 AWG wire; for two-up and three-up models (max. output
400 W and 600 W), use 2.5 mm2 / #14 AWG wire.
Input Voltage Connections. Connect the line voltage to L1 (hot) and L2N (neutral).
For one-up FlatPAC models (max. output 200 W), use #16 AWG input wire; for two-
up and three-up models (max. output 400 W and 600 W), use #14 AWG input wire.
Recommended connector screw torque is 5 to 7 in-lbs (0.5 to 0.8 N-m).
Recommended strip length is 8 mm. Use your FlatPAC model only with the
corresponding input voltages and frequencies shown in the table below.
Model 90–132 Vac 180–264 Vac
C– Grade VI–■■U–C ■■47– 63 Hz 47– 63 Hz
I– Grade VI– ■■U– I ■■47– 440 Hz 47– 440 Hz
Output Wire Gauge. Use the output wire gauge that corresponds to the output
current of your FlatPAC unit, below: Do not loosen bottom nut.
100 A–160 A : #2 AWG 30 A–50 A : #8 AWG 10 A–15 A : #14 AWG
75 A–100 A : #4 AWG 20 A–30 A : #10 AWG 6 A–10 A : #16 AWG
50 A–75 A : #6 AWG 15 A–20 A : #12 AWG 0 A–6 A : #18 AWG
Output Voltage Trimming. Do not trim the outputs higher than 110% of their
nominal output voltage. When an output is trimmed up, do not exceed its maximum
rated output power.
Operating Temperature. Do not allow the FlatPAC to exceed its maximum
operating temperature, which is reached when the heat sink is 85°C. (Full power can
be delivered up to this temperature.) Heat sink temperature is a function of the
output power and voltage of the supply, ambient temperature, and airflow across the
heat sink. Refer to the Vicor Applications Manual to determine the maximum ambient
temperature for your application. Always use worst-case conditions when
calculating operating temperature. Note 1: To ensure proper heat transfer from the
internal module(s) to the heat sink, the mounting holes through the heat sink (2, 3,
and 4 holes on one-, two-, and three-up models, respectively) must contain torqued
screws at all times during operation, whether or not the unit is mounted. If the unit is
operated unmounted, insert a #6 or metric panhead screw through each hole from
below and secure with a nut on top, torqued to 6 in-lbs (0.7 N-m). Note 2: All
FlatPAC models are available with a conduction cooled flat plate instead of the top
heat sink. Contact factory for outline drawings.

Input/Output Retrofit Connections. A hardware kit available from Vicor allows
the input and output supervisory terminals to be connected in the same manner as
for the earlier style FlatPAC (two-up model only). The retrofit output terminals are
sized to accept AMP Faston®insulated receptacle #2-520184-2.

Sicherungen. Die internen Sicherungen im FlatPAC können nicht vom Anwender
ausgetauscht werden. Für Servicearbeiten schicken Sie das Teil bitte an den Händler
zurück.
Erdung. Um den IEC 950 Klasse I Erdungsforderungen zu entsprechen, muß ein
Erdungskabel an den Anschluß (GND) angeschlossen werden. Für FlatPAC
Modelle mit einem Modul (max. Leistung 200 W) benutzen Sie bitte 1.5 mm2AWG
16- und für Modelle mit 2 und 3 Modulen (max. Leistung 400 W und 600 W) bitte 2.5
mm2AWG 14-Kabel.
Betriebstemperatur. Die maximale Betriebstemperatur des FlatPAC-Gerätes darf
nicht überschritten werden. Dies ist gegeben, wenn der Kühlkörper eine Temperatur
von 85 Grad Celsius erreicht hat. Die Kühlkörpertemperatur ist eine Größe, die sich
aus der Ausgangsleistung und Spannung der Stromversorgung, der
Umgebungstemperatur und der Luftzirkulation über dem Kühlkörper ergibt. Bitte
bestimmen Sie mit Hilfe des Vicor Applikationshandbuches die maximale
Umgebungstemperatur Ihrer Applikation.
Weitere Informationen. Das Vicor Applications Manual und Produkt-Datenblätter
enthalten ausführliche Informationen über FlatPAC AC-DC Wandler. Fordern Sie
bitte Unterlagen bei Vicor oder Ihrer nächsten Vicor Vertretung an.
