Designed for extended temperature operation (-40 to +85°C per MIL-STD-810G) and demanding power conditions dealt onboard military ground vehicles (MIL-STD-1275D) and aircraft (MIL-STD-704F) installations, this highly efficient (90%+), filtered DC/DC converter supplies DC voltage outputs (+3.3V, +5V, +12V) over the PC/104 (ISA) bus, PC/104-Plus (PCI) bus, or onboard screw clamp terminal. Featuring a rugged mechanical design, this small form factor (3.550” x 3.775”) card is designed to be used as the bottom card in a PC/104 system stack, operate without heatsinking or any active cooling, and provide resistance to high levels of shock and vibration. Featuring an onboard MIL-STD-461 EMI filter and transients protections for the 250V spike and 100V surge requirements of MIL-STD-1275, the card can replace the typical in-line power conditioning/EMI filtering devices integrated into military embedded systems. The product is offered in two output configurations: 40-watt or 80-watt to accommodate smaller to larger PC104(+) system power requirements.
