SynQor® Introduces I2C to its 3U 28 Vin VPX
Boxborough, MA – SynQor, Inc. announces the release of its 28 V input VITA 62 compliant
VPX Power Supply
in a 3U form factor with I2C functionality for monitoring and control. This
new option extends the capability of the 3U, 28 Vin VPX product family, which utilizes
SynQor's field proven MilQor® Mil-COTS product line.
The addition of the optional I2C functionality in SynQor's 3U, 28 Vin
VPX provides the user the ability to query the status of the power supply. This
feature allows the user to monitor input voltage, current and power status; output
voltage for each of the output rails; output current and power status for VS1, VS2
and VS3 outputs and three temperature readings at each card edge and the middle
of the VPX chassis.
The VPX I2C communication supports both PMBus® and IPMI interfaces
and complies with VITA 46.11 specification. The VPX dynamically identifies
which interface is being used based on the incoming data structure without the need
of any additional setup.
The 3U, 28 Vin VPX provides up to 500 W of total output power at 91% efficiency
to six standard VITA 62 outputs: +12 V @ 40 A; +3.3 V @ 20 A; +5.0 V @ 30 A; +3.3
VAUX @ 6 A; +/-12 VAUX @ 1 A each. The operating temperature is -40°C
to 85 °C at the card edge and the unit will deliver 100% of its power rating
up to the 85°C temperature.  The unit also incorporates a passive input
filter for MIL-STD-461F compliance. Input reverse polarity protection
is an additional feature within the I2C models. The +12 V
and the +5.0 V main outputs, as well as the +3.3 VAUX output, feature active current
sharing through a backplane connection for higher power paralleled applications. The
+/-12 VAUX outputs do not have current sharing, but they can be paralleled for redundancy.
The VPX Power Supplies
are designed to comply with MIL-STD-704 (level dependent) and MIL-STD-810G. They
have also been qualified to the most stringent levels of VITA 47. There
are two screening levels available and a conformal coating option.
products are available for evaluation and purchase. Datasheets and other
information are available on SynQor's website,
