Overview
The 3062322 is a high-power Cummins EFC-series electronic speed governor for large diesel engines (KTA19, KTA38, KTA50, QSK60). It drives high-current EFC actuators and is built for prime power plants, marine, and heavy industrial applications. This is the high-current variant of 3044196, capable of driving 500kW+ engines.
Key Features
- High-Power Output — Drives actuators up to 15A continuous for large fuel injection pumps on Cummins KTA38, KTA50, and QSK series engines
- Magnetic Pickup Speed Sensing — 600–9500Hz MPU input range with differential noise rejection for reliable RPM measurement
- Overspeed Shutdown — Configurable RPM threshold (1500–7500Hz) with <1.5 second response for large engine protection
- Soft-Start Acceleration — Programmable ramp rate prevents fuel over-fueling and black smoke during cold engine starts
- 24V DC Primary — Optimized for heavy-duty 24V generator electrical systems with surge protection to 32V
- Direct OEM Replacement — Drop-in replacement for Cummins 3062322 high-power EFC electronic speed governor
