Description Part Name: Diesel Generator Governor GAC ESD5500E   Description The ESD5500E speed governor is a full 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 sup-plied with a magnetic speed sensor signal, will control a wide variety of engines in an synchronous or droop mode.  It is designed for high reliability and built ruggedly to withstand the engine environment. Cummins ESD5500E speed governor Series is compatible with all GAC proportional actuators except the ACB2000 electric actuator.   The ESD5500E Series speed control unit is compatible with all  GAC proportional actuators except the ACB2000 electric actuator.   When the ESD5500E Series speed control unit is used with a ADC100 Series electric actuator, the DROOP adjustment  range will be less due to this actuator's low current demand.   Input  Supply  12 or 24 VDC Battery System (Transient and Reverse Voltage)  Polarity  Negative Ground (Case Isolated)  Power Consumption  50 ma continuous plus actuator current  Actuator Current Range @ 25   Deg.
