Description / Abstract:
This specification covers the requirements for solid-state
frequency converters with 480 [or 380] V 3-phase, 60 [or 50] Hz
input and 15/200 V, 3-phase, 400 HZ output capable of powering
aircraft type loads requiring MIL-STD-704D quality power.
The frequency converter shall be as 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.
