Product Description of T4800-31 Automatic Load Sharing Unit
The T4800-31 Automatic Load Sharing Unit (ALSU) is an advanced generator control and synchronization module designed to ensure stable, efficient, and uninterrupted power distribution between multiple diesel or gas generator sets. Built for industrial, commercial, and critical-facility applications, the unit automatically balances load demand across connected generators, preventing overload conditions while maximizing fuel efficiency and engine lifespan. It is an ideal solution for factories, hospitals, data centers, telecom towers, and large buildings where continuous power reliability is essential.
The controller continuously monitors generator voltage, frequency, phase angle, and load conditions in real time. When power demand increases, the T4800-31 intelligently starts additional generators and synchronizes them smoothly to the busbar without power interruption. When demand decreases, it automatically removes unnecessary generators from service, reducing fuel consumption, engine wear, and operating costs. Its precision load-sharing algorithm maintains equal kW distribution among generators, preventing uneven loading that commonly causes overheating, carbon buildup, and mechanical stress.
Designed with a user-friendly interface, the unit features a clear LCD display and configurable parameters, allowing technicians to easily adjust operating settings, protection limits, and communication options. Integrated protection functions include over/under voltage, over/under frequency, reverse power, overload, and synchronization failure detection. These protections safeguard both generators and connected electrical equipment.
The T4800-31 supports remote monitoring and control via RS-485 communication using Modbus protocol, making it suitable for SCADA and building management system integration. Its rugged industrial-grade construction ensures reliable performance in harsh environments with high temperature, humidity, and electrical noise conditions.
With fast response time, automatic synchronization capability, and intelligent load management, the T4800-31 Automatic Load Sharing Unit improves generator system reliability, extends maintenance intervals, and significantly reduces operational expenses. Whether used in parallel generator systems or standby power plants, this controller delivers dependable, automated power management for modern energy infrastructures.
