PWR-2X-11

PC/104-Plus & PCI/104-Express 100W / 50W Isolated DC/DC MIL-STD-1275/704 Power Supplies

The PWR-21-11 and PWR-22-11 boards are rugged MIL-STD-1275/704 compliant DC/DC converter cards in stackable embedded PC/104-Plus (PWR-21-11) and PCI/104-Express (PWR-22-11) form factors designed for demanding power conditions experienced by embedded computing devices used onboard military ground vehicles (MIL-STD-1275D) and aircraft (MIL-STD-704F) installations.

These galvanically isolated supplies provide 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. These boards provide power over stackable buses (PCI and ISA buses for PWR-21-11, PCI and PCI-Express buses for PWR-22-11) as well as auxiliary power output connectors for non-PC/104 systems. They support an 18-36V DC input range for 24/28VDC applications, and typically eliminate the need for additional in-line power conditioning/EMI filtering devices in military embedded systems.

Featuring a rugged mechanical design, these small form factor (3.550" x 3.775") cards are designed to be used as the bottom module in a PC/104, PC/104-Plus, PCI-104, PCIe104, or PCI/104-Express embedded system stack, operate without any active cooling over extended temperature ranges (-40 to +85C per MIL-STD-810G), and provide resistance to high levels of shock and vibration (per MIL-STD-810G fixed wing jet, rotary aircraft, and tracked ground vehicle conditions). They are 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 their robustness and versatility, the PWR-21-11 and PWR-22-11 power supplies are integrated into various MIL-STD-810/1275/704/461 qualified Parvus DuraCOR mission computers, DuraNET Ethernet switches, and DuraMAR mobile IP router subsystems. These small form factor supplies are compatible with Cisco Systems’ PCI-104 5915 Series Embedded Services Router (ESR) card as well as a host of embedded Single Board Computers modules on the market.
