Electrical Generator Speed Control Governor Unit- ESD5550E
The ESD5550E Speed Control Unit is a cutting-edge electronic device crafted to swiftly and precisely regulate engine speed, swiftly responding to fluctuating load demands. This closed-loop control system, when paired with a proportional electric actuator and a magnetic speed sensor signal, effectively manages a wide array of engines in either an isochronous or droop mode. Engineered for robustness, it withstands the demanding engine environment while ensuring high reliability.
Emphasizing ease of installation and adjustment, the design boasts non-interacting performance controls, simplifying the attainment of nearly optimal response levels. Key features include adjustments for engine STARTING FUEL and SPEED RAMPING, effectively reducing engine exhaust smoke typically encountered before reaching the operational speed.
