The ESD5500E Speed Control Unit is a rugged electronic engine speed governor controller designed to maintain consistent engine RPM and stable generator frequency under varying load conditions. It’s ideal for diesel generators, industrial engines and power systems where precise speed regulation is needed for reliable performance.
Where It Is Used
-
Diesel generator sets (gensets) requiring precise engine speed control
-
Industrial engines powering compressors, pumps, construction and mining equipment
-
Prime movers where stable RPM and smooth load transitions improve performance
-
Compatible with magnetic speed sensors and proportional actuators for full closed-loop control.
Key Functions & Features
-
Precise speed regulation: Maintains consistent engine speed under load changes (isochronous & droop modes) for stable generator output.
-
Electronic closed-loop control: Fast response to load variation and transient conditions.
-
Adjustable parameters: Idle adjustment, speed trim, droop settings and ramp control allow tailored performance.
-
Durable design: Built to withstand engine environment vibration and interference.
-
Wide compatibility: Works with 12V and 24V systems using proportional actuators and speed sensors.
Perfect for genset manufacturers, repair workshops, and power system integrators.
