Plane-Power debuts high-power alternator

GRANBURY, Texas — Plane-Power, Ltd. has received FAA approval of its newest lightweight, high-power aircraft alternator.

The Plane-Power ALT-FLX alternator is a lightweight, high-output, belt-driven alternator sold as a single part number for both 12V and 24V aircraft.

Optional mounting kits make it easy to replace heavyweight, Ford DOFF series alternators often used both Continental and Lycoming engines on Beechcraft, Cessna, and many other aircraft, according to company officials.

Weighing in at 12.5 lbs., the Plane-Power ALT-FLX alternator features a highly efficient hair-pin stator that enables extremely high power output even at low engine RPMs, officials noted.

During FAA testing, Plane Power ALT-FLX alternators proved to provide more than 150 amps on 28 volts continuously at typical engine cruise RPM. At just 1,000 engine RPM, the ALT-FLX generates more than 70 amps at 14 volts and 60 amps at 28 volts, company officials said.

“The ALT-FLX’s ability to function as a 14 or 28 Volt alternator is extremely innovative and a unique differentiator in the marketplace,” explains Jason Hutchison, General Manager of Plane Power, Ltd. “Weighing just over 12.5 pounds once installed, the ALT-FLX provides unmatched output per pound and is the perfect alternator for aircraft that require more output than traditional alternators can provide such as those with electric air conditioning systems.”

Every Plane-Power lightweight alternator is designed specifically for general aviation aircraft and features precision balanced components and tighter component tolerances to reduce vibration and maximize service life, officials said. All Plane-Power alternators also feature built-in noise filtering, simplifying installation by avoiding the need to install additional filters. All Plane-Power alternators are manufactured in the U.S. by Plane Power, Ltd. of Granbury, Texas.
