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).
