OVERVIEW
The ESD2100 Series speed control unit is an all- electronic de-
vice designed to control engine speed with fast and precise re-
sponse to transient load changes. This closed loop control, when
connected to a proportional electric actuator and supplied with
a magnetic speed sensor signal, will control a wide variety of
engines in an isochronous or droop mode. It is designed for high
reliability and built ruggedly to withstand the engine environment.
