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-DC converter that converts the
unregulated high-voltage bus to the desired regulated output voltage. Each ModuPAC can provide
up to 200W 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-DC converter that converts the unregulated high-voltage
bus to the desired regulated-output voltage. JuniorPACs can provide up to 100W of output power.
DualPAC™
This output assembly consists of two VI-J00 Vicor DC-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-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 200W 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).
