The ESD5500E Speed Control Unit is designed to precisely control engine speed with rapid response to transient load change. The ESD speed control is compatible with all GAC proportional actuator except the ACB 2001 electric actuator since this high torque actuator also requires current limiting. Ruggedly built to withstand all engine environments, the ESD’s starting fuel and speed ramp features will minimize engine exhaust smoke experienced prior to attaining engine operating speed and smooth out response.
The ESD5570 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, 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.
Starting Fuel and Speed Ramping adjustment 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.
