SOLID-STATE FREQUENCY CONVERTER 400 HERTZ, 3-PHASE OUTPUT
1989-09-01
HISTORICAL
ARP1940
This specification covers the requirements for solid-state frequency converters with 480 [or 380] V 3-phase, 60 [or 50] Hz input and 115/200 V, 3-phase, 400 Hz output capable of powering aircraft type loads requiring MIL-STD-704D quality power. The frequency converter shall be a self-contained unit suitable for the environment of intended use. Typical applications include dedicated use at passenger loading bridges (mounted under the bridge in telescoping bridge applications or fixed installation at base of stationary type loading bridges) with weatherproof enclosures or hangar/lab use where indoor fixed or portable units can be used.

400-CYCLE GROUND POWER UNIT PROVISIONS FOR AIRCRAFT ELECTRICAL SYSTEM PROTECTION
2002-12-16
CURRENT
ARP760
This SAE Recommended Practice which defines the terms and tabulates the limits of the characteristics for various protective devices used in conjunction with 400-cycle ground power for civil aircraft is intended to assist the airlines in standardizing on 400-cycle protective systems. The limits found to be acceptable in the civil aircraft industry are presented.

HISTORICAL
AIR1898
This SAE Aerospace Information Report (AIR) covers, and is restricted to, hands-on servicing/maintenance of industrial lead acid batteries used solely for motive power and exclusively for ground support equipment (GSE). It does not address or pertain to automotive-type SLI (starting-lighting-ignition) batteries or any other types of batteries (such as nickel-cadmium, zinc, or lithium batteries) which may be on-board airport GSE for either motive power or auxiliary uses. Similarly, the battery servicing and charging facilities described herein are those intended exclusively for industrial lead acid batteries.

GROUND ELECTRICAL POWER UNIT BRUSHLESS, SYNCHRONOUS, ELECTRIC MOTOR-DRIVEN 400 HERTZ, 3-PHASE OUTPUT
1985-08-01
HISTORICAL
ARP1480
This recommended practice outlines the general requirements of a continuous duty, electric motor-driven brushless alternator unit for supplying 400 Hz electrical power to high performance commercial transport aircraft. This specification is for a single motor-generator set with one or two outputs. The generator set will generate at the aircraft voltage of 115/200 volts. This unit may be used in a central system of small size or in hangar or electronic shop applications. Power characteristics of this unit at the receptacle will meet MIL-Standard-704 requirements. Other limits which are necessary to meet specific conditions must be specified by the purchaser.
