A rugged DC/DC converter card is designed for extended temperature operation (-40° to +85°C), high shock and vibration levels, and demanding voltage transient conditions experienced by military ground vehicles (MIL-STD-1275D) and aircraft (MIL-STD-704F) platforms, including 250V spikes and 100V surges. The ACS-5180 from Parvus is a stand-alone card and can be integrated into DuraCOR mission computers and DuraNET routers and switch subsystems. Featuring robust voltage input protections and onboard MIL-STD-461 EMI filtering, the card will typically eliminate the need for additional in-line power conditioning/EMI filtering integrated into such embedded systems. 

With a rugged mechanical design, this small form factor card is designed as the bottom card in a PC/104 system stack to operate without heatsinking or any active cooling and provide resistance to high levels of shock and vibration. This highly efficient, galvanically isolated power supply can supply 80 watts of power in military / civil ground vehicle, shipboard and aircraft applications over the PC/104 (ISA) bus, PC/104-Plus (PCI) bus, or screw clamp terminal. 

Key Features include a voltage input of 28.0 VDC, voltage outputs up to 80 watts at +5V@ 16A; +12V@ 2A and +3-3V@8A. Power input protection includes reverse polarity, voltage transient, surge, spike, over current and1500V galvanic isolation DC. Power output protection includes filtered output, current fold-back plus remote shutdown support and status indication. Formal qualification compliance testing is in process for MIL-STD-810G, MIL-STD-1275D, MIL-STD-704F, MIL-STD-461E.
