VPX 371 – Air Cooled – VITA 62 VPX Power Supply
WIENER VPX power supplies are commercial off-the-shelf (COTS), air or 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 VPX715 series offers highest output power on all 6 DC output channels which makes it a perfect power supply for test and development applications.
The VPX power supply mechanical dimensions are 3U x 8HP (1.60” slot). It is outfitted with front panel, connectors, keying and alignment mechanism as per VITA 62.
