About this file
This document appears to be a technical specification for a 400Hz generator. The key details are:
The generator must have an input voltage of 480 VAC, 3 phase, 3 wire, grounded with a voltage range of -10% to +10% of nominal. The input frequency is 50/60 Hz with a power factor of 0.9 lagging at full load. The rectification is active front end with a maximum of 5% total harmonic distortion (THD) at full load, 3% single phase.
The output is 115/200 VAC, 3 phase, 4 wire with a +/- 10% voltage adjustment range at 400 Hz. Other specifications include voltage regulation, frequency regulation, load power factor, transient response, overload capacity, phase angle, efficiency, and environmental requirements such as temperature, cooling, altitude, humidity, and audible noise.
This specification is referenced in a pre-solicitation for the Department of the Air Force Special Operations Command seeking 28VDC 400Hz generators (2 each) with installation and delivery to Cannon AFB, NM.
