Description

The ESD5550E GAC Speed Controller 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, can control a wide variety of engines in an isochronous or droop mode. Designed for high reliability and built ruggedly to withstand the engine environment.

ESD5550E GAC Speed Controller Series speed control unit features include:

  • Simple installation
  • Starting Fuel and Speed Ramping adjustments to minimize engine exhaust smoke prior to attaining engine operating speed
  • 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 event of loss of speed sensor signal or battery supply.
  • Light Force Actuation (ESD5570 only)

The ESD5550E GAC Speed Controller Series speed control unit is compatible with all GAC proportional actuators (except ACB2001). When paired with a GAC ADC100 Series electric actuator, DROOP adjustment range is less due to the ADC100’s low current demand.
