Solar 7399-2 2,500 Volt Spike Generator for MIL-STD-1399

MIL-STD-1399-300 establishes electrical interface characteristics for shipboard equipment utilizing AC electric power to ensure compatibility between the user equipment and the electric power system. In MIL-STD-1399-300, characteristics of the electric power system are defined and tolerances are established, as well as requirements and test methods for ensuring compatibility of the shipboard user equipment with the power system. The policies and procedures established by MIL-STD-1399-300 are mandatory. This section and the basic standard are to be viewed as an integral single document for use in the design and testing of electric power systems and user equipment. This standard supersedes MIL-STD-1399-103.   Classification In accordance with the MIL-STD-1399-300, the types of shipboard electric power to be supplied from the electric power system are classified as low voltage as follows: Type I - Type I power is 440 or 115 volts (V), 60 hertz (Hz) ungrounded and is the standard shipboard electric power source. Type I power is used unless a deviation is granted Type II - Type II power is 440 or 115 V, 400 Hz ungrounded and has only limited application. Use of Type II power requires the submittal and approval of a deviation request Type III - Type III power is 440 or 115 V, 400 Hz ungrounded having tighter tolerances as compared to Type II. Type III power has restricted use and its use requires the submittal and approval of a deviation request   Special power classification for avionic shops and aircraft servicing Types of shipboard electric power only for avionic shops and aircraft servicing are as follows: Type I - Type I power is 115/200 V, 60 Hz, 3-phase, 4-wire, wye-grounded. This power is only provided for avionic shops. Type III - Type III power is 115/200 V, 400 Hz, 3-phase, 4-wire, wye-grounded. This power is only provided for avionic shops and for aircraft servicing.   Special power classification for NATO load
