ESD5500E GAC Alternative Speed Controller
Keep the frequency steady: ESD5500E is a gac alternative speed controller for electronically governed generator engines.
About this part
A generator's frequency is set by engine speed. An electronic speed controller reads engine speed from a magnetic pickup and drives an actuator on the fuel rack to hold speed constant as load changes.
Features
- Isochronous Operation ± 0.25 % or better
- Speed Range / Governor 1 - 7.5 kHz Continuous
- Speed Drift with Temperature ±1 % MAX
- Idle Adjust Clockwise 60 % of Set Speed
- Idle Adjust Counterclockwise Less than 1200 Hz
- Droop Range 1 - 5 % regulation
- Speed Trim Range ± 200 Hz
- Remote Variable Speed Range 500 - 7.5 kHz
When to replace it
- Engine speed hunting or surging
- Frequency drifting under load
- Engine will not reach rated speed
- Overspeed shutdowns
Before you order
Match the controller to the actuator and supply voltage, and set gain and stability with the engine running, first off load and then with a load step.
If the old part has no readable number, send us a clear photo with the engine or alternator nameplate and we will identify it before you buy.
Questions
What is a droop kit for?
Droop lets engines share load when generators run in parallel, by letting speed fall slightly as load rises.
