B&C Alternator Spline Driven 20-30 Amp BC410-H with SB1B-14 14V - for Homebuilt

The B&C BC410-H-SB1B-14 is a 14 V spline-driven alternator configuration for experimental/homebuilt aircraft electrical systems. It combines the BC410-H externally regulated alternator with the SB1B-14 standby alternator controller.

The BC410-H mounts on a standard AND20000 vacuum-pump accessory pad and provides a nominal 20–30 A output, depending on engine cruise RPM. Its design features sealed ball bearings, dual cooling fans, a dynamically balanced rotor and a shear-section drive coupling.

The included SB1B-14 controller is intended for standby alternator control in a 14 V, single-bus, single-battery electrical system. It provides linear voltage regulation and solid-state over-voltage protection.
