3U power supply combines XMC mezzanine slot expansion and 6-port PCIe switch
NewsOctober 06, 2016
WASHINGTON. At the annual Association of the United States Army (AUSA) meeting, Curtiss-Wright?s Defense Solutions division introduced the 3U embedded power supply that also delivers system I/O expansion without increasing slot count. The PSU3-THOR power supply combines dual XMC mezzanine slot expansion and a 6-port PCI Express (PCIe) Gen2 switch into a 3U VPX slot unit.
The power supply was developed to enable system designers to provide 285 or 485 watts of power to support deployed applications while simultaneously reducing the 3U VPX system’s size, weight, power, and cost (SWaP-C) envelope. The PSU3-THOR’s built-in 24-lane 6-port PCIe switch provides the backplane interface for its dual XMC sites while eliminating the need for a separate XMC carrier or switch card. The PCIe switch also provides up to four extra x4 PCIe ports.
The PSU3-THOR 3U power supply takes 28VDC input power and features include 50 ms hold up time (to 280 W), is conduction-cooled, and has transient protection, current limiting, and polarity protection safety features. In addition, the PSU3-THOR hosts dual XMC (VITA 46.9) expansion mezzanine sites, up to 15 W each, and provides an embedded 6-port PCIe Gen2 switch.
