Product Overview
The DEIF LSU113DG is a load-sharing unit designed for generator control and power-management applications. DEIF load-sharing equipment is used to coordinate generator sets operating in parallel, helping distribute active load between generating units according to the configured control strategy. Such hardware is commonly found in marine power systems, standby generation, industrial plants, and decentralized power-generation installations.
The LSU113DG is intended for integration into a generator control architecture rather than standalone operation. Correct sensing, generator configuration, control wiring, and compatibility with the associated DEIF controller are therefore important when replacing the unit. Personally, I would verify the generator control schematic, voltage and frequency sensing arrangements, load-sharing signals, terminal configuration, and revision marking before approving a replacement.

Installation and Maintenance — LSU113DG
Before installation, isolate the generator control system and verify the original wiring against the approved control schematic. Check voltage and current sensing connections, load-sharing lines, governor interfaces, terminal assignments, and adjustment settings before energizing the replacement.
After installation, verify generator sensing, frequency response, load-sharing behavior, and parallel-operation performance. Testing should be carried out under the site’s approved commissioning procedure, particularly where multiple generators operate in parallel. Record the module’s serial number, configuration, and test results for future maintenance traceability.
Product Warranty — LSU113DG
Warranty conditions depend on the supplier and product condition. For new, refurbished, or repaired inventory, confirm warranty period, inspection status, test documentation, serial-number traceability, and return terms. A functional test report is recommended for critical generator-control applications.
The DEIF LSU113DG is best maintained as a configuration-specific generator-control spare. Confirming the generator architecture, sensing configuration, wiring, and associated controller before replacement helps ensure stable load-sharing performance.
