OVERVIEW
The ESD5500-II speed control unit is designed to precisely control
engine speed with rapid responses to transient load changes. The
ESD5500-II speed control is compatible with all GAC proportional actua-
tors except the ACB2001 electric actuator since this high torque actuator
also requires current limiting available in the ESD5300 Series.
Ruggedly built to withstand all engine environments, the ESD5500-II
has all the same well known features of the ESD5500 and also incorpo-
rates selectable light-force for low current actuators, dither for difficult
engines with respect to stability and integrated anti-windup for both
diesel and gaseous application.
