USA GAC ESD5500E Series Speed Control Unit
The ESD5500E Series Speed Control Unit is an all-electronic device designed to control engine speed quickly and precisely in response to transient load changes.
The ESD5500E controls a wide variety of engines in isochronous or droop mode when connected to a proportional electric actuator and magnetic speed sensor.
The ruggedly built ESD5500E series is designed to withstand the engine environment. Light-Force variations are available.
