MIL-STD-1399/390, MILITARY STANDARD: INTERFACE STANDARD FOR SHIPBOARD SYSTEMS (SECTION 390) ELECTRIC POWER, DIRECT CURRENT, (OTHER THAN SHIP'S BATTERY) FOR SUBMARINES (02 OCT 1987)

MIL-STD-1399/390, MILITARY STANDARD: INTERFACE STANDARD FOR SHIPBOARD SYSTEMS (SECTION 390) ELECTRIC POWER, DIRECT CURRENT, (OTHER THAN SHIP'S BATTERY) FOR SUBMARINES (02 OCT 1987)., This standard defines the electrical interface requirements for, and the constraints on, the design of submarine systems/equipments which will utilize direct current (dc) electric power. This standard does not apply to, nor shall be used for, the design of ship service dc power system load connected to the main storage battery. Submarine equipment designers and users of the system must comply with these interface and systems constraints/requirements when developing, producing and acquiring equipments to assure that satisfactory equipment operation and performance are obtained.
