28V DC Rectifier – DC Power Unit
The DOER 28V DC Rectifier is one ideal solid state Ground Power Unit for aircraft power supply, which has two kinds in design, stationary and trolley types in common, both two types are widely served at Aerodrome, designed to changes utility power to 28V dc aircraft power, compact in size and light in weight, with durability in lifetime exceed more than 25 years.
28V DC Rectifier solid state GPU, often in the form of Transformer Rectifier Units . It provides higher quality and stable 28V DC power for onboard systems, including engine start, aircraft maintenance on ground at apron or hangar eitherly by directly powering the starter or assisting the aircraft batteries strtup, to ensure predetermined voltage delivered from GPU to the aircraft.
