INTRODUCTION
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.
