GAC Electric Governor ESD5221E

Product Description
GAC ESD5220 SERIES SPEED CONTROL UNIT SPECIFICATIONS
The ESD5200 Series speed control unit is an all electronic device designed to control engine speed with fast and precise response 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.
Simplicity of installation and adjustment was foremost in the design. Non-interacting performance controls allow near optimum response to be easily obtained.
Other features include; Adjustable droop and idle operation, inputs for accessonries used in multi-engine or speacial applications, protection against reverse battery vollage, transient voltages, accidental short circuit of the actuator and fail-safe design in the event of loss of speed sensor signal or battery supply.
