ConverterPAC Functional Description

ConverterPACs are the family of slide-in output assemblies used in MegaPAC power 
supplies. Most ConverterPACs of the same length are interchangeable within a 
MegaPAC or between different AC input chassis.  They can be added, moved, or changed 
as necessary.   The following ConverterPACs can be used in the 3 Phase and 4kW 
MegaPACs.

ModuPAC

The ModuPAC output assembly consists of a VI-200 Vicor DC to DC converter that 
converts the unregulated high voltage bus to the desired regulated output voltage. Each 
ModuPAC can provide up to 200 Watts of power. Multiple ModuPACs can be paralleled 
in a driver-booster configuration to provide more power. 

JuniorPAC

The JuniorPAC consists of a VI-J00 Vicor DC to DC converter that converts the 
unregulated high voltage bus to the desired regulated output voltage. JuniorPACs can 
provide up to 100 Watts of output power.

DualPAC

This output assembly consists of two VI-J00 Vicor DC to DC converters that convert the 
unregulated high voltage bus to the desired regulated output voltages.

RAMPAC

This output assembly consists of a VI-J00 Vicor DC to DC converter with a Ripple 
Attenuator Module (RAM) and is designed for applications requiring low output ripple/
noise. 

BatPAC

The BatPAC output assembly consists of a VI-200 BatMod current source that converts 
the unregulated high voltage bus to the desired regulated output voltage. The BatPAC is 
a 200 Watts programmable current source that can be configured as a battery charger. 

UniPAC

The UniPAC output assembly consists of a Maxi Vicor DC-DC module that converts 
the unregulated high voltage bus to the desired regulated output voltage. UniPACs can 
provide up to 500W of power.  Multiple UniPACs can be paralleled in a driver-booster 
configuration to provide more power.  The UniPAC can only be used in the 4kW 
MegaPAC (not in the 3 Phase MegaPAC or any other MegaPACs).
