LS PWM Alternator Controller

The LS PWM Alternator Controller is a standalone solution for running a PWM-controlled LS alternator without an ECU.

It generates the required PWM control signal internally, allowing the alternator to regulate at a stable 14.6V charge voltage. Ideal for builds where the factory ECU control is removed or not available.

Designed and built in-house.
