Mechanical Considerations
The MicroPAC power supply can be mounted on four of the six surfaces using
standard 6-32 screws with a maximum torque of 7 inch-lb.
When using the mounting points the maximum insertion depth of the screw
into the chassis from the outside surface must not exceed 0.125”.
When considering a mounting location and/or orientation it is important not
to restrict the air flow entering and exiting the MicroPAC. Air is drawn into the
MicroPAC through the fan guard located next to the input power connector at the
rear of the power supply and exhausts through the load side of the power supply
next to the LED display panel. Westcor recommends a minimum clearance of 2”
be kept at the front and rear of the MicroPAC.
Care should be taken to minimize the output cabling as not impede the air
exhausting from the MicroPAC, the output screw securing the cabling to the
output terminals should be torque to 15 inc-lb not to exceed 20 inc-lb.

Output Power De-rating Curve
The MicroPAC is designed to operate from a single electrical phase; as such it can be
operated directly from a normal wall outlet socket. These sockets are normally rated
for 12 A continuous current draw and 15 A peak current draw. With this in mind it is
necessary to institute a power de-rating curve to maintain the operational range of the
MicroPAC within these boundaries.

MicroPAC to MicroPAC
Configuration
MicroPAC to MicroPAC Configuration
The MicroPAC power supply’s with the same output voltages can be placed in parallel
arrays by connecting the output positive (+) and return (-) rails to the respective positive
and return rails of the next MicroPAC. If individual Micro-PAC’s are configured in an
array it is necessary to make sure all MicroPAC are powered up at the same time. Where
possible the same AC source should be used to power all MicroPAC's in the array.
Pin 2 0 V (+5 V return) of the customer interface connector should be daisy chained
together on each MicroPAC in the array. The GSD signal Pin 8 should also be daisy
chained together and be used to turn on all outputs at the same time. The current
sharing is achieved by using the droop sharing method and produces in the order of 5
–10% current sharing accuracy (contact factory for details). It is important to note that
following good cable routing and symmetry is critical for good current sharing and load
balancing.
Pin 8 should be connected to Pin 2 on power up of the array. This will ensure all outputs
are held in the disabled state. Upon successful power up of the array Pin 8 should be
released and le open circuit, allowing all the outputs to be enabled.

Power Shed Mode
Introduction to the MicroPAC Power Shed Mode
The aim of the power shed mode is to increase the overall light load eciency of the
MicroPAC. This is achieved by minimizing the power dissipation when light load or no
load conditions are present on the MicroPAC output.
The original concept of improving light load eciency for VI Chip Bus Converter arrays
was developed by Mr. Ankur Patel (Vicor Product Line Engineer).
The following is an alternative method of power shedding
incorporated within the MicroPAC.
Power Shed Mode Prerequisites
nSlots 1 to 4 must be populated
nAll outputs must be the same voltage
nAll slots must be configured in a parallel array
nCurrent rate slew rate not to exceed 20.8 A/s
nThe PSM is not suitable for constant dynamic loads

Power Shed
Power Shed Mode Functional Description
On power up with the power shed function enabled all four output channels are initially
enabled, channel one to four LED’s should be illuminated. Circuitry internal to
the MicroPAC monitors the amount of current drawn from the MicroPAC and is
proportional to the customer load.
If the load falls into category 1, the following will be observed.
Aer 5 seconds output 4 will turn o, aer 10 seconds output 3 will turn o,
aer 15 seconds output 2 will turn o.
If the customer load falls into category 2, the following will be observed.
Aer 5 seconds output 4 will turn o, aer 10 seconds output 3 will turn o,
output 1 and 2 will remain on.
If the customer load falls into category 3, the following will be observed.
Aer 5 seconds output 4 will turn o, output 1, 2 and 3 will remain on.
If the customer load falls into category 4, all output will remain on.

Shoot First, Ask Questions Later
When the MicroPAC is operating in categories 1 to 3 and detects an increase in load
current applied to the output which incurs into the next power band the internal
microcontroller will turn all outputs on, regardless of the actual amount of load added.
(Shoot first ask question later) with all the outputs enabled, the microcontroller will
turn o redundant outputs
In the Power Shed Mode this is a constant cycle of detecting output load and continually
adjusting the outputs to satisfy that need.

J2 Customer Interface Signals
Note: All customer interface signals are referenced to the auxiliary +5 V return (Pin 2)
Auxiliary Supply
Pin 1 An auxiliary +5 V supply output is available with a maximum
output of 500 mA (2.5 W).
Pin 2 0 V; this is the return for the above +5 V.
ED/1 Enable/Disable Output Channel One
Pin 3 ED/1: This pin is normally at +5 V potential, this enables
output channel one. To disable output one this pin should
be shorted to Pin 2. If the output is disabled LED 1 will illuminate
on the LED display until the output is enabled.
Overtemperature Warning (Non Latching)
Pin 4 This pin is normally held at +5 V potential when referenced to
Pin 2. When running at 100% load at approximately 50°C ambient
temperature the overtemperature warning signal will be pulled low,
the fault LED indicator will illuminate solid yellow. This is just a
warning that you are approximately +5°C away from the maximum
operating temperature of the MicroPAC at full load.
Overtemperature Shutdown (Latching)
Pin 4 The same pin is used as the overtemperature warning.
At approximately +56°C if running at 100% load the overtemperature
shutdown is triggered. The fault LED previously illuminated a solid
yellow due to the overtemperature warning will now begin to flash
at approximately 2 Hz. All outputs of the MicroPAC will be
automatically disabled. The power supply will go into a shutdown
mode; however the fan will be le running to cool the unit, the
MicroPAC will remain in shutdown mode until the temperature reaches
an acceptable level and the power is recycled.
ED/3 Enable/Disable Output Channel Three
Pin 5 ED/3: This pin is normally at +5 V potential, this enables output
channel three. To disable channel three this pin should be shorted
to Pin 2. If the output is disabled LED 3 will illuminate on the LED
display until the output is enabled.
Power
Pin 6 If the AC or DC power input is present the pin is normally at +5 V
potential when referenced to Pin 2. The blue power LED will illuminate.
If the AC or DC input is lost Pin 6 will fall to logic level zero and the
blue power LED will turn o. This will allow a minimum 10 mS power
loss warning to the customer.

Page 14
J2 Customer Interface Signals (Cont.)
Standby Mode
Pin 7 This pin is normally at +5 V potential when referenced to Pin 2. If this
pin is shorted to Pin 2 the MicroPAC will enter a low power standby
mode. In this mode all outputs will be disabled, the main PFC power
supply will be shut-down along with the fan. The blue power LED will
change to an amber color. When the short is removed the power supply
will return to normal operation and the power LED will turn to blue.
General Shut Down (GSD)
Pin 8 This pin is normally at +5V potential when referenced to Pin 2. If this
pin is shorted to Pin 2 all the channels will be disabled and all four of
the GSD LED’s (1-4) will illuminate.
Fan Fault (Latching)
Pin 9 This pin is normally at +5V potential when referenced to pin 2.
In the event of the fan failing the detection circuit will shut the
MicroPAC down, and illuminate the fault LED red. Pin 9; will go from
logic high to logic low level during this event. The MicroPAC will be
latched in this condition until power is removed for 30 seconds, upon
reapplying power if the fault is still persist the power supply will latch
in the shut-down mode until the fault has been cleared.
Ed/2 Enable / Disable Output Channel Two
Pin 10 This pin is normally at +5V potential, this enables output channel two.
To disable channel two this pin should be shorted to Pin 2. If the output
is disabled LED 2 will illuminate on the LED display until the output
is enabled
Not Connected
Pin 11 Pin 11 is not u sed
Ed/4 Enable/Disable Output Channel Four
Pin 12 This pin is normally at +5 V potential, this enables output channel four.
To disable channel four this pin should be shorted to Pin 2. If the output
is disabled LED 4 will illuminate on the LED display until the output
is enabled.
