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 up to 600 W. The two-up and

three-up models (maximum output 400 W and 600 W) 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 switchers 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 controlled

output voltage. Consequently, the output supervisory terminal functions differ on

FlatPACs with BatMod modules.

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. For safe operation, the FlatPAC unit must be grounded. Connect a ground lead to the terminal marked (GND). Use the same wire gauge as that specified for your FlatPAC unit’s input voltage connections, below. Input Voltage Connections. Connect the line voltage to L1 (hot) and L2N (neutral). For one-up FlatPAC models (max.

If the unit is operated unmounted, insert a #6 or metric screw through each hole from below and secure with a nut on top, torqued to 6 in-lbs (0.7 N-m). Output Terminal Connections. A hardware kit with parts for output terminal connections is provided with each FlatPAC unit. The following drawing shows the assembly of those parts for the proper connection of metal power terminals. Assembly for PCB power terminals is the same except that they do not require an external tooth lockwasher.

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 200W) benutzen Sie bitte AWG 16- und für Modelle mit 2 und 3 Modulen (max. Leistung 400 W und 600 W) AWG 14-Kabel.
