VPX336 - Medium Power / Flexible Configuration - VPX Power Supply

WIENER VPX power supplies are commercial off-the-shelf (COTS), conduction cooled, single stage converters according to the ANSI/VITA 62.0 specification. They can be used to power a VPX chassis and will fit into the standard envelope defined by VITA 48.0 specifications.

Using state of the art switching power technology, a wide input voltage range as well as high overall efficiency is achieved. Further each individual main converter is oversized for maximum current which allows different VPX336 power supply configurations having either a stronger 12V or a more evenly distributed power over the 3 main output channels.

The new VPX336 series is designed in compliance with MIL-STD-461, 704 and 1275 as per VITA 62. An embedded microprocessor allows monitoring and control via I2C bus and USB.
The VPX power supply mechanical dimensions are 3U x 4HP (0.80” slot). It is outfitted with connectors, keying and alignment mechanism as per VITA 62.
