PCI/104-Express 100W/50W Isolated DC/DC MIL-STD-1275/704 Power Supply

The PWR-22-11 board is a rugged MIL-STD-1275/704 compliant DC/DC converter cards in stackable embedded PCI/104-Express form factor designed for demanding power conditions experienced by embedded computing devices used onboard military ground vehicles (MIL-STD-1275D) and aircraft (MIL-STD-704F) installations.


• 100 Watt PCIe104 Power Supply
• MIL-STD-704F & MIL-STD-1275D Compliance
• MIL-STD-461F EMI Filter / Power Conditioning
• 18V to 36VDC Input Range
• +3V, +5V, +12V DC Output
• Extended Temperature: -40 to +85°C
• MIL-STD-810G Shock/Vibe/Thermal


• 24/28V DC-DC Conversion for PCI-104, PCIe104, PCI/104-Express and Other Small Form Factor Embedded Systems
• Compliance with MIL-STD-1275, MIL-STD-704, MIL-STD-461 Surges, Spikes, Conducted Emissions in Aerospace / Avionics / Military / Ground Vehicles
This galvanically isolated supply provides 100 watts of combined power output (+3.3V, +5V, +12V) and come equipped with MIL-STD-461 EMI filtering and transient protections specifically designed for demanding 250V spike and 100V surge requirements under MIL-STD-1275. This board provides power over the PCI-Express stackable bus as well as auxiliary power output connectors for non-PC/104 systems. It supports an 18-36V DC input range for 24/28VDC applications, and typically eliminates the need for additional in-line power conditioning/EMI filtering devices in military embedded systems.

Featuring a rugged mechanical design, this small form factor (3.550” x 3.775”) card is designed to be used as the bottom module in a PCIe104, or PCI/104-Express embedded system stack, operates without any active cooling over extended temperature ranges (-40 to +85°C per MIL-STD-810G), and provides resistance to high levels of shock and vibration (per MIL-STD-810G fixed wing jet, rotary aircraft, and tracked ground vehicle conditions). It is passively cooled by attaching the bottom of the card to a thermally conductive base or enclosure wall with electrically-isolated gap pad to dissipate heat. A tribute to its robustness and versatility, PWR-22-11 power supply is integrated into various MIL-STD-810/1275/704/461 qualified Eurotech DuraCOR mission computers, DuraNET Ethernet switches, and DuraMAR mobile IP router subsystems. This small form factor supply is compatible with a host of embedded Single Board Computers modules on the market.
