VPX340 - High Efficiency / Medium Power

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 range voltage range as well as high overall efficiency is achieved. The VPX340 and VPX315 series is designed in compliance with relevant MIL STD 461, 704 and 1275. An embedded microprocessor allows monitoring and control via I2C bus.
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.
