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. Product Description The MicroPAC is a factory configurable power supply providing up to 1,300 W of continuous power in a small slimline 1 u package. The power supply provides up to 4 isolated outputs and combines power factor correction along with high efficiency and power density. The MicroPAC boasts a power density of 25 Win3 and efficiency up to 92%, the power supply is available in a wide temperature range configuration and for harsh environments and mil-cots applications conformal coated. All configurations carry full safety agency approvals i.E. Ul60950 en60950 and are CE marked.

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.

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 left open circuit, allowing all the outputs to be enabled. Figure 3. MicroPAC to MicroPAC Configuration vicorpower.com Applications Engineering: 800 927.9474 Page 6 Power Shed Mode Introduction to the MicroPAC Power Shed Mode The aim of the power shed mode is to increase the overall light load efficiency 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 efficiency 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 Configuring Power Shed Mode The Power Shed Mode is factory configured. Power Shedding Bands There are four operational modes for the power shedding scheme. Table 2.

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. After 5 seconds output 4 will turn off, after 10 seconds output 3 will turn off, after 15 seconds output 2 will turn off. If the customer load falls into category 2, the following will be observed. After 5 seconds output 4 will turn off, after 10 seconds output 3 will turn off, output 1 and 2 will remain on. If the customer load falls into category 3, the following will be observed. After 5 seconds output 4 will turn off, output 1, 2 and 3 will remain on. If the customer load falls into category 4, all output will remain on. Figure 4.

(Shoot first ask question later) with all the outputs enabled, the microcontroller will turn off 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.

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 left 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 off. This will allow a minimum 10 mS power loss warning to the customer. vicorpower.com Applications Engineering: 800 927.9474 Page 13 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. vicorpower.com Applications Engineering: 800 927.9474 Page 14 J2 Customer Interface Signals (Cont.)
