Curtiss-Wright’s Innovative New 3U Power Supply is First to Integrate Dual VITA 46.9 XMC Sites and 6-Port, 24 Lane PCIe Gen 2 Switch

AUSA 2016, WasHINGTON, D.C. (Booth #319) – October 3, 2016 – Curtiss-Wright’s Defense Solutions division today introduced the industry’s first 3Uembedded power supply that also delivers system I/O expansion without increasing slot count. The rugged PSU3-THOR power supply combines dual XMC mezzanine slot expansion and a 6-port PCI Express® (PCIe) Gen2 switch all in a single 3U VPX slot unit. It enables system designers to provide 285 or 485 watts of power to support today’s demanding deployed applications while simultaneously reducing their 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 power supply’s PCIe switch also provides up to four extra x4 PCIe ports, significantly expanding overall system I/O. The PSU3-THOR power supply is ideal for use in today’s latest generation of high performance small form factor 3U based embedded systems. It also provides a compelling solution for expanding the capabilities of legacy 3U systems through technology refresh. 

“Many of our customers face the daunting challenge of reducing the size of their embedded subsystems while deploying more power and I/O hungry processing performance,” said Lynn Bamford, Senior Vice President and General Manager, Defense Solutions division. “Over the last 5 years, we have seen average system size requirements decrease by up to 40%, while the power required for the latest technology has increased over 50%. That’s what makes our new PSU-THOR power supply a breakthrough for system integrators. It’s the industry’s first 3U form factor power supply to deliver XMC card expansion and a 6-port PCIe Gen2 switch all in a single compact unit.” 

About the PSU3-THOR Power Supply

The innovative PSU3-THOR 3U power supply takes 28VDC input power (either MIL-STD-704, MIL-STD-1275, or DO-160) and delivers clean output voltages to power today’s high performance 3U modules. It’s performance features include: 

• 28 VDC input power

• 285 or 485 watts of output power (expansion to 485W requires no re-work)

• 50 ms hold up time (to 280 W)

• Outputs: 5V, 3.3V, and +/- 12V

• Conduction-cooled

• Transient protection, current limiting, and polarity protection safety features

• Voltage and temperature sensors with an elapsed time indicator

In addition, the PSU3-THOR uniquely hosts dual XMC (VITA 46.9) expansion mezzanine sites (up to 15 W each) and provides an embedded 6-port PCIe Gen2 switch.
