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.
