B&C Alternator Special Case Mount Kit For Other Starter L-40 with LS-1B 28V - for Homebuilt

The B&C L-40-SC-LS-1B is a special case-mount L-40 alternator configuration for homebuilt aircraft, supplied for 28 V electrical systems with the B&C LS1B external controller/regulator. The product designation is intended for installations using a starter other than a B&C starter.

The L-40 is a 40 A, belt-driven alternator platform designed by B&C Specialty Products for aircraft electrical systems requiring a lightweight power source. B&C describes the L-40 design as using sealed heavy-duty ball bearings, built-in cooling fans and a dynamically balanced rotor. The alternator is externally regulated; the included LS1B controller/regulator is designed for use with B&C wound-field alternators in 28 V systems and provides adjustable linear voltage regulation, over-voltage protection, and low-voltage monitoring.
