ESD5500-II Fusion Series – Analog Governors
(Isochronous, Variable & Droop Operation / Speed Ramping / Starting Fuel Control / Enhanced Droop Control / Anti Wind-Up Circuit / Soft Coupling / Selectable Light-Force Capability / Dither Function)
The next generation of GAC’s Speed Controllers, the ESD5500-II Fusion Series combines all of the most popular functions of the various ESD5500 Series (5500, 5520, 5526 & 5528) into a single, high-performance unit. 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 actuators 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 incorporates 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.
Features:
| Adjustable Droop and Idle Circuits |
| Selectable Light-Force and Dither |
| Idle Speed Adjustment |
| Anti Wind-Up |
| Variable Speed Operation |
