For
more than 40 years, Champion (formerly WAGNER ELECTRIC) brand power
supply products have been specified for airborne use, ground support,
and marine requirements. As the acknowledged leader in power
conversion, this complete line of Transformer-Rectifier Units (power
supplies) can be custom tailored to your specifications. Champion
Aerospace has also pioneered design improvements in its power supply
line—now with ratings up to 300 amperes. And, by simulating operational
environments and stresses, Champion’s power supplies meet virtually
every design objective required by airframe manufacturers.
Lightweight Power Supplies
They provide rigid
physical support, full circuit enclosures, and optimum, uniform heat
dissipation. The unique "Y" configuration reduces weight and space
factors in our designs. This also allows the power supplies to be
mounted in any position, fan or blast cooled and have far greater
flexibility in termination and terminal locations.
These
products are known for reliability (near linear voltage regardless of
load variations) and the ability to withstand extremes in altitude,
temperature, shock, vibration, and gravity. They are qualified to Mil
Standards controlled by the US Navy. For avionics upgrades to military
commercial and corporate aircraft which require additional DC power,
Champion TRU's offer an off the shelf rugged and economical solution to
the need to convert engine AC to 28 VDC.
PCTRU Power Quality Improvements
Conventional
wisdom says that while unregulated TRU are more robust than regulated
TRU they have higher DC ripple voltage. With the latest Champion
Passive Controlled Transformer Rectifier Unit (PCTRU) this is no longer
the case. Tests have shown that Regulated TRU DC ripple voltage which
meets Mil Std 704 exceeds the 5% noise modulation limits for proper
communication function. PCTRU DC ripple Voltage is 90 % lower. The
PCTRU is available on 50 to 300 ampere TRU.
NEW PRODUCT: DC Bus Hold-Up Unit 28VUPS27F
Champion has designed and delivered to the US
military for a helicopter application a new product , the 28VUPS27F
which provides continuous DC power to onboard equipment such as
NAV/GPS, COMM, FLIR, CPU. CM etc during transient power interruptions,
such as switchover from APU or ground power to main engine. These
units are qualified to MIL-STD-704 A-F AND EMI by the US Navy.
