Curtiss-Wright has announced the rugged PSU3-THOR power supply which integrates the dual XMC (VITA 46.9) mezzanine slot expansion and a 6-port PCI Express (PCIe) Gen2 switch in a single 3U VPX unit. The built-in 24-lane, 6-port PCIe switch backplane supports dual XMC sites using separate XMC carrier or switch card. Four extra x4 PCIe ports are available for I/O expansion. The conduction-cooled unit has system output power of 285 or 485 watts with 50 ms hold up time (to 280 W) while output voltages are 5V, 3.3V, and +/- 12V. Input power is 28VDC and complies with MIL-STD-704, MIL-STD-1275, DEF-STAN or DO-160. Up to 15 watts are supported by each XMC (VITA 46.9) mezzanine slot. Temperature is operational from -40 to +85 degrees C with humidity from 0 to100 percent condensing. Safety designs include transient protection, current limiting, and polarity protection. Voltage and temperature sensors are built-in with an elapsed time indicator.

In today's demanding size, weight, power and cost (SWaP-C) environment, the PSU3-THOR power supply is the first in the industry to reduce the overall system size in many rugged applications. The unit measures approximately 1.49 (H) x 3.93 (W) x 7.10 (L) inches and weighs 1.4 lbs. In the past five years, Curtiss-Wright has reduced the overall system size by 40% with increased functionalities and continued to support the legacy 3U VPX.
