Lamar B-00368-2 ALTERNATOR CONTROL, 28V FOR PIPER AIRCRAFT

The **Lamar B-00368-2 Alternator Control Unit** (P/N **B-00368-2**) is a 28 V aircraft electrical control component used in compatible Piper single-engine alternator charging systems. Designed for continuous PWM operation, the unit provides alternator field control and voltage regulation, with a factory voltage setting of 28.0 V and a maximum field load current of 4 A. The B-00368-2 incorporates overvoltage protection that shuts off regulator output following an overvoltage event. It also includes protection against field output short circuits, with reset achieved by momentarily switching off the supply voltage. Listed by Lamar under its FAA-PMA-approved 28 V alternator control products, the B-00368-2 is associated with **Piper P/N 584-290** and is eligible for selected Piper PA-28, PA-32 and PA-38 aircraft models. --- ## Applications Suitable for applicable: - **28 V aircraft electrical systems** – Alternator field control and voltage regulation - **Piper PA-28 Series** – Selected Cherokee, Warrior, Archer and Arrow models - **Piper PA-32 Series** – Selected Cherokee Six, Saratoga and Lance models - **Piper PA-38-112** – Tomahawk aircraft applications - **Aircraft electrical system maintenance** – Replacement of compatible alternator control components --- ## Why CJ Aerospace?
