Alternator Platforms

Alternators | Conversion Kits | Voltage Regulators

Plane-Power offers multiple alternator platforms supporting both legacy replacement and modern aircraft applications.

FAA PMA Certified Alternators

Delivering reliable electrical power across a wide range of aircraft applications.

PRESTOLITE STYLE

Direct-fit PMA replacements for legacy OEM alternators with widespread use across existing aircraft platforms.

ES SERIES

Internally developed alternators supporting OEM and PMA applications across piston aircraft, single-engine turboprops, light jets, and UAV platforms. High power density designs provide reliable performance across demanding electrical requirements.

ASG SERIES

OEM and PMA replacement alternators for select Cessna applications and legacy 24V Ford systems, incorporating durability and performance improvements over original designs.

AL SERIES

Lightweight alternator replacements for older OEM units. Supplied with mounting hardware to support flexible installation where direct-fit options are not available.

C/E SERIES

Direct-drive alternators designed specifically for Continental engine applications, offering modern performance in a compact configuration.

JASCO SERIES

Alternators supporting legacy aircraft and generator replacement programs, including STC conversion applications for vintage platforms.

Generator to Alternator Conversions

FAA STC-approved conversion kits replace outdated generator systems with modern alternators, improving performance, reducing weight, and enhancing reliability.

Overhauled & Exchange Alternators

Factory-overhauled alternators are available on an exchange basis, providing a cost-effective alternative to new units. Each unit is rebuilt with new critical components including brushes, diodes, and bearings, and tested using the same equipment and standards as new production.

Support is also available for legacy systems, including Ford and Chrysler alternators, using PMA-approved replacement parts and certified overhaul processes.

Voltage Regulation Systems

Solid-state voltage regulators provide stable electrical output, built-in protection features, and simplified configuration for both new installations and legacy upgrades.
