Civilian and military aircraft require reliable, high-performance power supplies to ensure safe operation in a variety of environmental conditions. Created in 1959, MIL-STD-704 has and continues to set the standard for aircraft power sources. It underwent several revisions over the last few decades to correct errors and standardize test methodologies. The current revision \u201cF\u201d was issued in March of 2004 and updated in December 2016. Read on to learn more about MIL-STD-704 requirements and why they\u2019re crucial for ruggedized power supplies.<\/a><\/p>\n<\/div><\/div><\/div>

What is MIL-STD-704?<\/h2>\n

MIL-STD-704 is a military specification that defines and outlines the requirements for compatibility between the airborne utilization equipment (power supplies) and the aircraft power system (including the external sources for the power system).<\/p>\n

It also establishes the characteristics that the power system needs to provide at the utilization equipment power terminals. The standard covers multiple areas for AC and DC systems including:<\/p>\n<\/div><\/div><\/div>
