MIL-STD-704F Power Supply
Power supplies for military aerospace applications are designed to meet the interface requirements of MIL-STD-704. This specification defines the interface standards for military aircraft electric power characteristics. The standard specifies normal, abnormal, transfer, emergency and starting operating characteristics for parameters such as voltage and frequency.
A MIL-STD-704F Power Supply must be able to operate under the defined characteristics of at least one of the revisions of the standard, whether it be the base revision released in 1959 through to Revision F (with Change 1) released in 2016.
