270 Vdc Aircraft Power Supply

The 270vdc power supply may also be used in conjunction with a 270vdc uninterruptible power supply ups attached to the bus for critical mission equipment affected by ac bus transfers low voltage sags and other ac dc interruptions.

270 vdc aircraft power supply.

The rugged plug in design allows for easy access and replaceability. Where does the decision to go with 270 vdc come from. Mobile 270 vdc cart with power and cable fixed 270 vdc units full suite of tests are available for these units such as emi per mil std 461 e shock per mil std 901 d and vibration per 167. Unitron 270vdc aircraft power supply units are available in ratings from 36kw to 72kw in mobile towable and fixed configurations.

Act 270 v dc power supplies have survived in severe environments such as wide temperature ranges and high altitude. All our aerospace power supplies are extensively tested and can be modified in various ways to better suit your needs. The mil std 704 power connections provide the store with access to 28 vdc three phase wye 400 hz 115 200 vac and 270 vdc aircraft power. Many applications require hermetically sealed units.

It is usual to route only one of the last two supplies however if both are made available then they are never made active simultaneously. This high precision power supply has been fully tested and supports these aircraft under all adverse load conditions. This ac dc power supply converts the 115 vac three phase 400 hz input power into 270 vdc which is then used to power a number of dc dc converter modules. It also accepts 28 vdc aircraft power and conditions this voltage for distribution within the system.

This allows utilization equipment to maintain full operational capability and ride through these interrupts. Engineering complex power supply for f 22 test program in the early 2000s the engineering staff from edwards air force base afb distributed an inquiry regarding a power supply for a 270 vdc military aircraft. I had heard that it was derived from using 3 phase 400 hz 115 200 vac power but i m not sure how do the conversion to get 270 vdc. This 270vdc product line is designed for use in both indoor and outdoor environments for maintenance ground support of the f 22a raptor and the jsf 35 as well as mro s supporting the aircraft.

Fcx did not initially respond to the inquiry however no viable solutions were presented by the 11 companies that did respond.
