More Information

Introducing the ESD5330 Diesel Engine Controller, a cutting-edge speed control unit designed specifically for generator sets. This state-of-the-art governor is meticulously engineered to optimize performance and enhance reliability, ensuring efficient and smooth operation of your diesel engine.

The ESD5330 boasts an impressive range of technical specifications that set it apart from other speed control units on the market. With a supply of 24 ± 20% VDC battery systems, this controller offers an excellent level of protection against transient and reverse voltage. Its polarity is negative ground, ensuring a safe and isolated case.

One of the key features of the ESD5330 is its isochronous operation, which guarantees steady-state stability of ±0.25% or better. This is crucial for maintaining a consistent speed range of 1K to 7.5K Hz, enabling your generator set to adjust seamlessly to varying power demands. Additionally, it ensures that speed drift with temperature remains within ±1 Max, ensuring optimal performance even in extreme conditions.

For added flexibility, the ESD5330 allows for idle adjustment within a range of 25-85% of rated speed. This means you can customize the idle speed according to your specific requirements. Furthermore, the controller offers adjustable droop ranging from 0-5% for a 1.5 A actuator current change, giving you greater control over generator set operation.

Another notable feature of the ESD5330 is its remote variable speed range, which allows you to adjust the speed from 25% to 100% of its rated speed. This feature is invaluable when precise control of the engine speed is necessary for specific applications.

When it comes to environmental resilience, the ESD5330 excels. It can operate within a wide temperature range, from -40 to +85 degrees Celsius, making it suitable for various climates and conditions. Its surface finishes are fungus-proof and corrosion-resistant, ensuring longevity and reliability in rugged environments. In addition, it can withstand vibrations of up to 1G at 20 to 100 Hz, as well as shocks of 10 G (11 ms), making it perfect for even the harshest working environments.

To guarantee its reliability, the ESD5330 is 100% functionally tested before leaving the factory, ensuring that all components are in perfect working order. This level of quality control gives you peace of mind that the controller will perform flawlessly throughout its lifespan.

With the ESD5330 Diesel Engine Controller, you can be confident in delivering optimal performance, reliability, and efficiency for your generator set. Its cutting-edge features and robust construction make it an ideal choice for a wide range of applications. Don't compromise on the quality of your speed control unit - choose the ESD5330 for exceptional performance and peace of mind.
