  • Page 3: Overview Of Product

    Overview The FlatPAC-EN/EN MI is an ultra low profile switching power supply that provides up to 500 Watts from up to 4 isolated outputs. It operates on either 115 or 230 Vac nominal (47-63 Hz), or 250-380 Vdc. It can be populated with either VI-200/VI-J00 or Maxi/Mini/Micro Vicor converters.

  • Page 4: Mechanical Considerations

    2. For standard mounting (conduction cooling), use A1, A2, A3, A4, B1 and B2 mounting holes. 3. For a Vicor 2 Up FlatPAC retrofit replacement, use C1 and C2 as these two are identical to the recommended mounting holes on the FlatPAC.

  • Page 5: Technical Description

    FlatPAC-EN/EN MI Design Guide Technical Description The FlatPAC-EN/EN MI consists of an off-line single phase autoranging front end, EMI filter, customer interface, power supply control circuit, associated housekeeping circuits, a MiniHAM module and a selection of Vicor’s VI- 200/VI-J00 and/or Maxi/Mini/Micro DC-DC converters.

    USE CRIMP TOOL: MOLEX (11-01-0197) Note: The type of output connector a FlatPAC-EN has depends on which modules are used. E.g. if a two output configuration uses two half bricks (instead of a full brick and half brick) this two output configuration will have the 18 pin molex connectors, not stud connectors.

  • Page 13: Interface Connections

    Output Power Connections There are two types of output power terminals available in the FlatPAC-EN. Each slot has one of the following configurations: either 10-32 plated steel bolts or an 18 pin Molex connector (The type of output connector a FlatPAC-EN has depends on which modules are used.

    The operating mode setting is stored in a non-volatile EEPROM and requires an REON or REOFF command in order to switch modes. The default mode setting from the factory is in Manual mode. The FlatPAC-EN has an operating mode indicator LED, which is viewable through the left side vent hole nearest the CBJ1 E/D Interface Connector.
