Overview
The 3098693 is a Cummins EFC-series electronic speed governor for NTA855, KTA19, and VTA28 diesel engines. It provides precise closed-loop RPM control with isochronous operation for standby and prime power generator sets.
Key Features
- EFC Governor with 4.5A Output — Maximum 4.5A continuous actuator drive for proportional fuel control actuators up to 50 lb-ft
- MPU Speed Sensing — 600–9500Hz magnetic pickup input for non-contact engine RPM measurement with noise-immune differential signaling
- Over-Fueling Protection — Limits actuator current during startup to prevent excessive fueling and black smoke on cold cranking
- 12/24V Operation — Wide DC input range (8–32V) eliminates need for separate voltage-specific governor models
- Auxiliary Speed Input — Supports remote speed adjustment via external potentiometer or PLC analog output for load-sharing applications
- OEM Replacement — Direct fit for Cummins 3098693 EFC governor; compatible with Cummins N14, K19, K38, K50 engine series
