700-Watt Ruggedized, Programmable Power Supply
Plug-in Module, Conduction-Cooled, Six Outputs
Description
NAI’s VPX56-6 is a 700-Watt AC/DC Power Supply that plugs directly into a standard 6U VPX chassis with a VITA 62 1.0” power supply
slot. This off-the-shelf solution for VITA 46.0 and VITA 65 systems is compatible with VPX specifications; supports all VITA standard I/O,
signals, and features; and conforms to the VITA 62 mechanical and electrical requirements for modular power supplies.
The VPX56-6 programmable power supply is conduction-cooled through the card edge/wedgelock. It accepts 3Ø AC or +270 VDC input and
provides six outputs and I/O at up to 700 Watts.
The VPX56-6 supports a variety of standard features, including continuous Background Built-in-Test (BIT); remote error sensing; holdup
time; and protection against transients, over-voltage, over-current, and short circuits. With its intelligent design, the VPX56-6 also has the
flexibility to address special needs. Options include current share and alignment keys for input and output configurations.
This COTS power supply is specifically designed with NAVMAT component derating for rugged defense and industrial applications. It is also
designed to meet the many harsh environmental requirements of military applications.

Signal Types
Signal
Description
ENABLE*
Turns off all of the output voltages, including 3.3 V_AUX, when signal is High. ENABLE* is pulled Low by using a
mechanical switch which connects it to SIGNAL_RETURN. A Logic output can also be used to drive the ENABLE*.
Opening the switch would turn off all the outputs; closing the switch or applying the Logic output would enable the
outputs to come on depending on the state of INHIBIT*. An input of <0.8 VDC is regarded as a Low and an input of
>2.0 VDC is regarded as a High. A no-connect is also regarded as a High. Along with INHIBIT*, this signal
determines the output power status of the VPX56-6 (see Power Status Table, page 5).
INHIBIT*
Turns off all the output voltages. In most implementations, the signal is expected to leave 3.3 V_AUX on. Pulling
INHIBIT* Low turns off VS1, VS2, VS3, and ±12 VDC_Aux outputs. An input of <0.8 VDC is regarded as a Low and
an input of >2.0 VDC is regarded as a High. A no-connect is also regarded as a High. Along with ENABLE*, this
signal determines the output power status of the VPX56-6 (see Power Status Table, page 5).
SYSRESET*
An active low open-collector line driven by the Power Monitor module. Signal ensures a clean, stabilized startup
based on monitoring the output voltage levels in accordance with VITA 46.0, paragraph 4.8.11. Timing can be
factory customized.
FAIL*
Indicates failure when any of the outputs are not within specification. Signal complies with VITA 65 for active Low.
FAIL* signal is Open Drain. It is expected that there will be a pull-up resistor on the backplane.
Geographical
Addressing
As defined in VITA 46
Current Share
Allows multiple power supplies to share system load for VS1, VS2, and VS3 outputs. Connection is made per
designated pins for each output.

I2C Communication
1.
Hardware Interface.
Electrical interface is based on I2C parameters at 100 kHz. The backplane or I2C master controller should provide pull up resistors on SDA
and SCL lines to a 3.3V rail.
2.
Address.
The I2C Hardware Address (per VITA 46.11 Rev 0.15) is 7 bits. The default base address is 0x20. *GA0 through *GA4 provide the 5 LSB’s
for the address.
The *GA pins have 3.32K pull‐up resistors to a 3.3V rail. The resistors and the 3.3V rail are internal to the power supply. When left open, the
address will be 0x20, otherwise, the address will be as described in the table below.

6 = 6U
Series 56 = VPX AC/DC
* Note:
Per VITA 62, all 6U power supplies must use three alignment keys, numbered 1 through 3. These keys are used as part of the
VPX56-6 part number and indicate both the input and output configuration of the unit being ordered.
Key 1 = Input Voltage Range
Key 2 = Input Voltage Type; DC, 1Ø AC or 3Ø AC
Key 3 = Output Configuration
Example Part Number: VPX56-61AABDCA-00
Equals VPX Power supply AC/DC, 6U. 1.0" pitch, no internal battery, current share on VS1, VS2 and VS3, Input Voltage 85V to 265V,
3 Phase AC input, Std VPX Outputs, no additional options
