ESD5221 Speed Control Unit Engine Governor Controller for Diesel Generator Alternator Genset

The ESD5221 speed control unit is an all electronic device designed to control engine speed with fast and precise response to transient load changed. 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 reality 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 accessories used in multi-engine or special applications, a single element speed switch, protection against reverse battery voltage, transient voltages, accidental short circuit of the actuator and fail-safe design in the event of loss of speed sensor signal or battery provide.
