UGS-11 ULS11 LOAD SHARING UNIT.
UGS-11 / ULS11 Load Sharing Unit – Product Description
The UGS-11 (ULS11) Load Sharing Unit is a precision electronic control module designed for reliable parallel operation of multiple diesel or gas generator sets. It ensures equal and stable load distribution between generators, preventing overload on any single unit while maximizing system efficiency and operational lifespan.
In multi-generator power plants, uneven load sharing is one of the most common causes of overheating, reverse power tripping, unstable frequency, and premature engine wear. The UGS-11 solves this issue by providing a fast and accurate load balancing function using analog control signals and droop/isochronous governor compatibility. It works seamlessly with electronic governors, AVR systems, and synchronizing panels, making it suitable for both new installations and retrofit projects.
The unit operates on a 24V DC supply and features high noise immunity, ensuring stable performance even in electrically noisy industrial environments such as factories, hospitals, telecom stations, marine systems, and large commercial buildings. Its compact DIN-rail mountable design simplifies installation inside generator control panels and synchronization switchboards. The front-panel calibration adjustments allow engineers to fine-tune gain, stability, and load matching without requiring complex programming tools.
With built-in protection against signal fluctuation and load hunting, the ULS11 enhances generator reliability, reduces fuel wastage, and improves overall plant efficiency. When used in automatic synchronizing systems, it maintains smooth load transfer during generator addition or removal, minimizing power disturbances to connected equipment.
It offers dependable performance, easy commissioning, and long-term durability, making it a preferred choice for generator control panel manufacturers and power system integrators.
