ESD5570E GAC Alternative Speed Controller
The ESD5570E GAC Alternative Speed Controller is part of the system that holds a generator engine at constant speed, and so the output at constant frequency.
About this part
When speed control fails, the engine hunts, overspeeds or cannot pick up load, and the frequency drifts out of tolerance.
Features
- Simple installation
- Adjustable droop and idle operation
- Inputs for accessories used in multi-engine or special applications
- Light Force Actuation (ESD5570 only)
- Isochronous / Steady State
- Stability ± 0.25 % or better
- Speed Range / Governor 1 K - 7.5 K Hz continuous
- Speed Drift with Temperature ±1 % MAX
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.
Not sure it is the right one? A photo of the old part and the nameplate of the machine it came off is usually all the counter needs to confirm a match.
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.
