28.5 VDC Generator by AP Manufacturing


The direct current 28 volt generator was specially design to work with a wide range of small aircraft and helicopters that need 28 V-DC to start their engines. The design, versatile, modern and powerful, makes the unit unique against competitors because it has been created by a service provider company incorporating the improvements for an easy operation and a good maintenance of the equipment.

Concept & Design. The idea, design and its conception.

 

easier_simple1 The conception of the e28 was planned from all the experiences had with other ground support equipment for over 30 years; today, the evolution in technology and electronics offers equipment that are more compact, sealed and non-reparable, because of this, the design and engineering team at AP Manufacturing decided to focus in a more simplified mechanical and electronic process of voltage generation, offering this new design that offers a reliable voltage output with simple systems with automatic voltage built-up, it’s exterior was designed for easy access to the unit with removable panels created in galvanize metal sheets; the control panel provides easy operation by four simple buttons and a graphic interface that can be understood by anyone.
