Overview
The FlatPAC-EN/EN MI is an ultra-low-profile switching power supply that provides up to 500W from
up to four isolated outputs. It operates on either 115 or 230V
It can be populated with either VI-200/VI-J00 or Maxi/Mini/Micro Vicor converters. The use of these
converters gives the FlatPAC-EN/EN MI the inherent power flexibility typical of all Vicor products. With
dimensions of 1.4in H [35,6mm] x 5.0in W [127mm] x 9.2in L [233,7mm], the FlatPAC-EN/EN MI provides
a power density greater than 7W/in
Note: The FlatPAC-EN/EN MI does not have an internal fan.
The MI version is a rugged chassis designed specifically for COTS and harsh environment applications.

    Thermal Curves converters gives the FlatPAC-EN/EN MI the inherent power flexibility typical of all Vicor products. With dimensions of 1.4in H [35,6mm] x 5.0in W [127mm] x 9.2in L [233,7mm], the FlatPAC-EN/EN MI provides Current Share Boards a power density greater than 7W/in .
  • Page 2 This feature is implemented in all converter slots (except with Micro modules). Autosense allows automatic local sensing when remote-sense connections are not made. The FlatPAC-EN™/EN MI will operate in remote-sense mode when remote-sense connections are made. Refer to Page 18 for more information on Autosense.
  • Page 3 For standard mounting (conduction cooling), use A1, A2, A3, A4, B1 and B2 mounting holes. 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. For increased ruggedness, additional mounting holes can be used to secure the power supply.
  • Page 4 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 VI-200™/VI-J00™ and/or Maxi/Mini/Micro DC-DC converters.

    CRIMP TOOL: MOLEX (11-01-0199) Output Power Connections There are two types of output power terminals available in the FlatPAC-EN™.

  • Page 14 Power Supply to be a slave via the RS-232 interface. Operating Modes The FlatPAC-EN has two operating modes, remote and manual, which can be set using the RS-232 interface feature. The operating-mode setting is stored in a non-volatile EEPROM and requires an REON or REOFF command in order to switch modes.
  • Page 15 The protocol is an ASCII character stream that will be sent back and forth between the power supply and the user. The FlatPAC-EN™/EN MI in the remote mode will be considered a slave in that it will only respond to commands and requests and will not initiate conversations. Communications are half-duplex in that only the FlatPAC-EN/EN MI receiver or transmitter may be active at one time.
  • Page 16 TON1, TON2, TON3, TON4 Turn On commands for modules 1, 2, 3, or 4. These commands turn on the module identified by the trailing digit. If an automatic sequence is in effect at the time this command is received, a reply of "Inv Command" is returned; otherwise "OK"...
  • Page 17 These pins should be open circuited or allowed to exceed 4.5V when enabled. Do not apply more than 5V to these inputs. Figure 4 Enable/Disable mode FlatPAC-EN™ A TTL "1" applied to the base of the transistor turns output OFF. Pin 1 (or Pin 7 for GSD) is pulled Low with respect to Signal Ground.
  • Page 18 – simply hook up the outputs and the FlatPAC-EN will automatically operate in local-sense mode. To check if an output has the Autosense feature, measure the impedance from the +OUT to +SENSE and –OUT to –SENSE pins. If the impedance is 5Ω, then the output has Autosense and does not require local sense jumpers.
  • Page 19 External Trim (Not applicable when using BatMod™ current source) The TRIM pin can be used for external control of the output voltage. TRIM connections on single- and dual-output connector for output M1 is J1-1 while for output M2 is J2-2. TRIM connections on triple-output connectors for output M1 is J2-6, for output M2 is J3-6 and for output M3 is J3-14.
