VIPAC combines application specific Power processing units (PPU), a choiceof chassis styles and remotelylocated hold up capacitors to provide fast, flexible and highlyreliable Power solutions for a wide range of demanding PPU is the core element of the system and may be specified for 115/230 Vac operation.

2 The PPU incorporatesVicor s autoranging FARM modular front-end to provide transient protection, EMI filtering and inrush current limiting. The web-based PowerBench enables designers to configure thePPU with up to three independently regulated outputs havingpower levels from 50 to 500 W and with as much as 900 Wtotal output Power . Vicor s Maxi, Mini, Micro Family DC-DCconverters, in industry standard quarter, half and full brickpackages, are used to deliver output voltages from 2 to 48 , the wide trim range of the modules can provideoperating voltages as low as 500 mV.

3 The PPU is comprised of: AC input modular front end Vicor s Maxi, Mini, Micro Family high densityDC-DC converters Coldplate or finned chassis Choice of output termination stylesThe VIPAC is offered in several chassis configurations facilitatingits use in a variety of applications using either conduction, convection or forced convection cooling. The low profile, conduction cooled version may be mounted to an existing cabinet wall, coldplate or heat sink. The " or 1" finned versions, available in longitudinal or transverse configurations,are ideal for use in free or forced convection environments.

4 Theuse of standard chassis footprints allows different input voltageconfigurations of the VIPAC to be used interchangeably dependingon system and market use remotely located capacitors to facilitate packagingand placement options not previously available. The low profilePPU can be placed closer to the load or attached to cabinetwalls while the capacitors may be integrated into the host systemaway from heat sources for improved reliability. System hold up /ride-thru requirements can also be tailored for specificapplications via different value capacitors. The hold upcapacitors may be obtained from Vicor as a prepackaged hold upbox (HUB).
