PSU3-THOR 3U 28 VDC Power Supply with Embedded XMC Carriers

In today’s market, customers are looking for ways to improve size, weight and power (SWaP) in their systems while keeping up with the demand for higher powered cards. Customers are also looking for ways to increase I/O count without having to add additional slots forcarrier cards which increase the cost and size of the system.

The PSU3-THOR 28 VDC power supply provides a flexible power design that can range from 250 watts to 500 watts of power. It has been designed to meet harsh environments for both ground and airborne applications. Power supply safety features include transient protection, current limiting, and reverse polarity protection. There is also an option that incorporates a 50 millisecond hold-up for temporary power interrupts up to 280 watts.

In addition to providing clean power to a system, the PSU3-THOR power supply also includes embedded, high speed digital interface. Utilizing the two XMC sites, the system’s overall I/O count and capability increases without having to increase slot count. The PSU3-THOR also includes an embedded six port PCI Express® (PCIe) Gen2 switch. This not only allows access to the two XMC sites, but will also provide three additional x4 PCIe ports to the backplane; adding flexibility to the architecture.
