APECS 4800 Controller

APECS 4800 Controller

The APECS 4800 control system combines a digital electronic controller with a rotary or linear actuator to provide speed control of diesel engines under 75 hp (56 kW). The system provides accurate, reliable, and durable control over the service life of the engine in the extreme operating environments found in power generation and industrial applications.

The 48-pin digital controller provides isochronous speed control, actuator position control, torque limiting, droop, glow plug control, CAN J1939-based communications, and additional engine management and protection functions to optimize engine operating efficiency.

The 4800 can provide emissions control for NOx with EGR valve control and particulate material reduction through smoke limiting.

Primarily used for engine governing on small generators, the 4800 system is also well-suited for throttle actuation on off-road light utility vehicles or construction equipment. Typical applications include stationary and mobile generator sets, construction machinery, and farm vehicles.
