MegaPAC Family

Configurable AC/DC Power Supply with 1-24 Output and up to 2400 Watt

Description

The MegaPAC Family from Vicor’s Westcor Division consists of eight fan-cooled, configurable power supplies that enable users to factory configure almost any set of output requirements by combining appropriate slide-in output assemblies called ConverterPACs, with the appropriate chassis. The MegaPAC chassis has a standardized feature-laden front end with slots to accept the ConverterPACs. Models are available with single or three-phase AC inputs. MegaPACs will also operate from high-voltage DC input. Features include EMI / RFI filtering, enable / disable, general shut down, output sequencing. and AC OK.

* Westcor’s Vantage Line is priced at approximately 15% below standard one piece price. It provides a new, affordable power option for power designers who may not need to meet certain specifications.

Description ConverterPACs

ConverterPACs are the family of slide-in output assemblies used in MegaPAC Power Supplies. There are currently 13 ConverterPACs available for use. Most ConverterPACs of the same length are interchangeable within a MegaPAC and between different AC input MegaPAC chassis. They can be added, moved, or changed as necessary.

ConverterPACs incorporate VI-200 or VI-J00 and / or Maxi Vicor DC-DC converter bricks. For additional power, ConverterPACs can be paralleled. Some ConverterPACs are available for low-noise applications (VXI options, RamPACs and QPACs) and as current sources (BatPACs). All ConverterPACs can be easily removed in the field by loosening a single screw and sliding the unit out of the chassis.

Specifications of ConverterPACs

Output Voltages:
  • 2 – 95 Vdc (higher through series arrays)
Output Power:
  • Up to 600 W
Efficiency:
  • 80 – 90%

Features of ConverterPACs

  • RoHS compliant (see individual data sheets for associated RoHS letter)
  • DC OK / Power Good option available
  • Adjustment ranges from 50% to 110% of nominal on some models
  • Low noise options to 10 mV p-p or 0.15% whichever is greater on some models
  • Current source outputs available
