All PFC MegaPACs have the same input and output connections, mounting points, and
the same dimensions:

The extended length (-EL) chassis is covered in a dierent design guide

A complete power supply is configured at the factory by selecting and inserting up to
eight same length slide-in output assemblies called ConverterPACs. ConverterPACs
incorporate one (or more) VI-200/VI-J00), Maxi Vicor DC to DC converters and/or
FlexPACs and are available in a wide selection of output voltage and power levels.
The net result is a power supply that oers the advantages of a custom supply, but is
assembled from standard and modular building blocks. Currently, the standard power
chassis uses only FlexPACs and ConverterPACs with VI-200/VI-J00 Vicor DC to DC
converters while the high power chassis accepts FlexPACs and ConverterPACs with
both VI-200/VI-J00 and/or Maxi module. (Refer to page 6 for a brief overview of the
ConverterPACs used.) Using the PowerBench configurator tool available on

www.vicorpower.com, anybody can now configure a PFC MegaPAC (and other Westcor
power supplies) online.

Manufactured at Westcor, a division of Vicor, the entire family of MegaPAC power
supplies is completely user-configurable. If output requirements change, i.e., more
power or a dierent output voltage is needed, upgrading is easy: simply unlock a
single screw and replace the slide-in ConverterPAC assembly with one that is of
the same length and has the desired voltage power rating. For additional flexibility,
ConverterPACs can be connected in parallel to increase output power (booster
ConverterPACs), or in series for higher voltages (total output voltage should not exceed
400 V). The driver is to the le of the boosters when looking at the output end of the
supply. A user-friendly interface provides control and output sequencing capability
(see page 30 for more information about this capability), in addition to useful status
indicators. Please consult our Applications Engineering Department if you have other
special requirements.

Mechanical Considerations

The PFC MegaPAC can be mounted on any of four surfaces using standard 8-32 or
4mm screws. The chassis comes with four mounting points on each surface; maximum
allowable torque is 5.5 lb-in. The maximum penetration is 0.15 in. (3.8mm).

When selecting a mounting location and orientation, the unit should be positioned
so air flow is not restricted. Maintain a 2" minimum clearance at both ends of the PFC
MegaPAC and route all cables so airflow is not obstructed. The standard unit draws air
in at the fan side/AC input side and exhausts air out the load side. If airflow ducting is
used, use caution, as sharp turns could present back pressure to the PFC MegaPAC. The
fan moves approximately 30 CFM of air.

Avoid excessive bending of output power cables aer they are connected to the PFC
MegaPAC . For high-current outputs, use cable ties to support heavy cables in order to
minimize mechanical stress on output studs. Be careful not to short-out to neighboring
output studs. The PFC MegaPAC units are supplied with serrated, flanged hex-nuts on
all output studs. Therefore, thread locking compounds or lock washers are not required.
The maximum torque recommended on flanged nuts is 45 lb-in. Never loosen the inner
nut on a ConverterPAC. This nut supports the hardware inside the ConverterPAC and is
factory torqued.

Avoid applications in which the unit is exposed to excessive shock or vibration levels. In
such applications, a shock absorption mounting design is required.

MegaPAC Do’s and Don’ts

n Remote sense should be used:

- To improve poor output regulation.

- When using older ConverterPACs that do not have the autosense feature.

n NEVER connect the remote sense wires in reverse.To avoid failures, always terminate

the +Sense to the +Out and the -Sense to the -Out.

n If needed, compatible connector kits can be ordered separately. Refer to page 25 for

additional information regarding connector kits.

n To avoid overheating, NEVER operate the supply with an open output slot. Open slots

should always be filled with a ConverterPAC or a plastic airblock designed for
the PFC MegaPAC.

n Always turn the power supply OFF before disconnecting any input or output wires.

Failure to do so may lead to an electrical shock hazard and or damage to
the power supply.

n Do not insert or remove a ConverterPAC while the power supply is running.

They are not designed for hot insertion or extraction.

n Wait 5 minutes aer shutting o the power supply before inserting or

removing a ConverterPAC.

n Do not restrict airflow to or from the supply as this can cause overheating damage.

n Booster ConverterPACs are available for power expansion. Refer to page 6 for

additional information.

n Do Not use boosters as independent outputs. Operating boosters with disconnected

bus bars will cause failures.

n Before turning on the unit ensure all input and output wire are properly connected

and all hex nuts properly tightened.

n Keep output wires as short as possible and run the output (+/-) power cables next to

each other. Use twisted pair wiring whenever possible.

UG:105 vicorpower.com Applications Engineering: 800 927.9474 Page 3

n Avoid running input and output wiring in close proximity as this may cause noise

related problems.

n PFC MegaPACs are NOT user serviceable. Please contact our customer service

department at 1-800-735-6200 for repair assistance. Please be advised that attempts
to repair or modify the power supply will void the warranty.

n A proper fault protection device (fuse or breaker) should be used in series with

the input terminals.

n Use proper size wires to avoid overheating and excessive voltage drop.

n NEVER loosen the inner nut on a ConverterPAC.

n FinPAC ConverterPACs can only be used with a high power chassis. A high power

chassis is identified by an “MX” prefix code in the specific model number.

n Output voltages over 60 Vdc, whether from individual modules or series arrays, are

considered as hazardous secondary outputs under UL 60950. Appropriate care must
be taken in design implementation of the supply.

Technical Description

The PFC MegaPAC chassis consists of an o-line single phase, power-factor-corrected
front end, EMI filter, cooling fan, customer interface and associated housekeeping
circuits. Input AC mains voltage (L1, L2 and GND) is applied to a terminal block. The
input current is passed through an EMI filter designed to meet conducted noise limit “B”
specifications of FCC Part 15, VDE 0871, and EN55022 class A At start-up, inrush current
is limited by a PTC thermistor. The PTC is shunted out shortly aer initial power-up by
a DC bus voltage Sense circuit driving a relay. Aer rectification, the input voltage is put
through a boost converter that keeps the AC input current sinusoidal and synchronized
with the AC input voltage (in compliance with EN61000). The boost converter delivers
regulated high voltage DC to the hold-up capacitors and backplane. The backplane
supplies power to a variety of ConverterPAC assemblies that provide the desired
regulated outputs.

Voltage conversion in the output assemblies is achieved by Vicor’s family of
Zero-Current-Switching (ZCS) DC to DC converters. These are forward converters in
which the main switching element switches at zero current. This patented topology has
a number of unique attributes: low switching losses; high frequency operation resulting
in reduced size for magnetics and capacitors; excellent line and load regulation; wide
adjustment range for output; low EMI/RFI emissions and high eciencies.

At initial power-up the PFC MegaPAC outputs are disabled to limit the inrush current
and to allow the DC bus potential to settle out to the correct operating level. A low­power flyback converter operating with PWM current-mode control converts the
high voltage DC bus into regulated low voltage to power the internal housekeeping
circuits and DC cooling fan. The internal housekeeping Vcc comes up within 2 s aer
the application of input power. Once the high voltage bus is within its limits, the AC
OK signal asserts to a TTL “1” indicating the input power is OK, and enables the power
outputs. An auxiliary Vcc output of 5 Vdc sourcing up to 0.3 A is provided for
peripheral use.

An output Enable/Disable function is provided by using an optocoupler to control
the Gate In pins of the ConverterPAC assemblies. If the Enable/Disable control pin is
pulled low, the optocoupler turns on, pulling the Gate In pin low and disabling the
ConverterPAC output. The nominal delay for an output to come up when measured
from release of the Enable/Disable pin is 10-15 ms. The General Shutdown function
controls all outputs simultaneously and works in a similar manner.

UG:105 vicorpower.com Applications Engineering: 800 927.9474 Page 4

The ride-through (holdup) time is the amount of time the load can be supported before
loss of output regulation aer the loss of input power. Detecting the loss of input power
takes a finite time period aer which the AC Power OK signal goes from a TTL “1” to “0."
This signal is available for use within 1.2 seconds aer initial power-up and can be used
to indicate an impending loss of power. At least 3 ms of warning time is given. Following
the loss of input power, the outputs are disabled when the bus voltage drops below its
operating threshold.

Configuring and Reconfiguring MegaPACs

Most ConverterPACs of the same length can be inserted into any available slot of a
MegaPAC chassis. They can also be easily added, replaced, or moved by sliding the
assemblies in or out of a MegaPAC chassis. (Currently, two exceptions are the FinPACs
which can only be used in the high power chassis and the UniPACs which can only be
used in the 4 kW MegaPAC.) For outputs greater than 200 Watts, a driver ModuPAC
and one or more booster ConverterPACs will be used. For outputs greater than
600 Watts, a driver FinPAC and one or more booster ConverterPACs will be used.
Arrays of drivers and boosters should be configured so all boosters are placed in the slots
to the immediate right of the driver when looking at the output end of the MegaPAC.

Prior to removing or installing ConverterPACs, you must remove power from the
MegaPAC and wait 5 minutes. Failure to do so can result in personal injury or
damage to the supply.

Take standard ESD precautions when handling ConverterPACs.

Removing ConverterPACs

ConverterPACs can be removed by loosening the captive screw at the base. Once
this screw has been loosened, the ConverterPAC will slide out of the chassis. Once a

ConverterPAC has been removed, the empty slot MUST be filled with either another
ConverterPAC or an airblock. If the slot is le empty, it will provide an airflow escape

and cause failure to the power supply.

Installing ConverterPACs as Drivers

ConverterPACs can be installed in empty slots by simply sliding in the new
ConverterPAC and securing the screw at the base. Power and interface connections can
be made aer the ConverterPAC has been installed.

Paralleling ConverterPACs

Installing Booster ConverterPACs to Increase Output Power

ConverterPACs can be paralleled for more power. Additional power to an output is
obtained by connecting one or more boosters in parallel with a single driver. The
driver can be placed in any open slot. All boosters should be inserted in the slots to
the immediate right of the driver as viewed from the output end of the MegaPAC.
Figure 2 shows a driver placed in slots #1 and 3 boosters placed in slots # 2 to 4. Aer
inserting the driver and boosters, they are paralleled using bus bars across the positive
and negative output studs. Drivers should not be paralleled with each other. Bus bars
between a driver and booster (s) should never be disconnected. For help in identifying
boosters and drivers, refer to the Part Numbering section on page 8. Please note that
total output voltage should not exceed the converter baseplate-output isolation rating of
400 V. For detailed guideline on how outputs should be placed in series, please refer to
the Applications note (Creating high voltage outputs) available on the
website at www.vicorpower.com.

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 and between dierent AC input MegaPAC chassis (Exceptions are the FinPAC
and UniPAC). They can be added, moved, or changed as necessary. The following
ConverterPACs can be used in the PFC MegaPAC and/or PFC MegaPAC-High Power.

Spec sheets for ConverterPACs are available at www.vicorpower.com

ModuPAC

The ModuPAC output assembly consists of a VI-200 DC to DC converter that converts
the 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. ModuPACs are fused with a PC-Tron, DC-rated,

+

fast-acting fuse. A passive LC filter is used to reduce output ripple/noise down to 1%

_

typical, and 2% maximum peak-to-peak from 10% to 100% of rated load. An optional
DC Power Good signal, or output voltage Trim potentiometer can be specified. The
ModuPAC contains overvoltage protection (OVP), overcurrent protection (OCP), and
overtemperature limiting (OTL). The OCP has automatic recovery when the overcurrent
condition is removed. The OVP and OTL are latching functions and require recycling of
the AC input power to restart.

JuniorPAC

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

+

output power and are fused with a single PC-Tron, DC-rated, fast-acting fuse. A passive
LC filter is used to reduce output ripple/noise down to 1% typical, and 2% maximum

_

peak-to-peak from 10% to 100% of rated load. An optional DC Power Good signal or
output voltage Trim potentiometer can be specified. The JuniorPAC contains output
overcurrent protection, which recovers automatically when the overcurrent condition is
removed. Overvoltage protection and overtemperature limiting are not available.

M1

DualPAC

This output assembly consists of two VI-J00 DC to DC converters that convert the high

M2

voltage bus to the desired regulated output voltages as noted above. The outputs are
electrically isolated. For detailed pin out description, refer to page 10.

RAMPAC

This output assembly consists of a VI-J00 DC to DC converter with a Ripple Attenuator

+

Module (RAM) and is designed for applications requiring low output ripple/noise. The

_

RAMPAC can attenuate the ripple/noise down to 10 mV peak-to-peak over a 20 MHz
bandwidth from 10% to 100% of rated load of the converter.
Outputs from 5 V to 50 V are available.

a PC-Tron, DC-rated, fast-acting fuse. The BatPAC is a 200 Watts programmable current

_

source that can be configured as a battery charger. Maximum current and voltage
settings are controlled using potentiometers that come as a standard feature, or through
Trim pin access as an option. BatPACs are available for 12 V, 24 V and 48 V
battery systems.

FINPAC

The FinPAC output assembly consists of a Maxi DC to DC converter that converts the
unregulated high voltage bus to the desired regulated output voltage. Each Maxi module

+

can provide up to 600 Watts of output power. Each FinPAC occupies 2 slots because

_

it has an extra large heatsink attached to dissipate the heat generated by this more
powerful Maxi converter. Currently, the FinPAC is ONLY used in the high power (MX)
chassis. It cannot be used in any other member of the MegaPAC Family.
Contact Westcor for future updates.

FlexPAC

The FlexPAC output assembly consists of from 2 to 4 discrete outputs that convert the
high voltage bus to the desired output voltage. Each FlexPAC output can be manually
trimmed from 2 V to 25 V and supports up to 5 amps with a maximum output power
of 50 W per output. All outputs maintain less than 50 mV noise over the entire output
range. All outputs support local sense only. For electrical trim options and specific
output sequencing contact the factory.
