GAC ESD5500-II Series Speed Control Unit

Governors of America GAC ESD5500-II Series Speed Control Unit. 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 varety of engines in an isochronous or droop mode. It is designed for high reliability and built ruggedly to withstand the engine environment. The primary features of the ESD5500 series are the engine starting fuel and speed ramping adjustments. the use of these features will minimize engine exhaust smoke experienced prior to attaining engine operating speed. Other features included adjustable droop and idle operation, inputs for accessories used in multi-engine or special applications, protection against reverse battery voltage, transient voltages, accidental short circuit of the actuator and fail safe design in the even of loss of speed sensor signal or battery supply. The ESD 5500 series is compatible with all GAC proportional actuators except the ACB2001 electric actuator. When the ESD 5500 series is used with a ADC100 actuator, the droop adjustment range will be less due to this actuator's low current demand.
