SELCO T4800-31 Load Sharer | Marine Generator Load Sharing Controller | SELCO Generator Synchronizer
The SELCO T4800-31 Load Sharer is a highly reliable marine generator load-sharing and synchronization controller designed for diesel generator power management systems onboard ships and offshore installations. It automatically balances electrical load between multiple generators operating in parallel while ensuring stable frequency, voltage, and power distribution.
The T4800 continuously monitors generator output, synchronizing conditions, reverse power, breaker status, and system frequency. By automatically controlling generator loading and unloading, it improves fuel efficiency, minimizes mechanical stress, prevents generator overload, and significantly reduces the risk of vessel blackout.
Designed for demanding marine environments, the SELCO T4800 is widely installed on commercial ships, offshore platforms, naval vessels, and industrial power plants where uninterrupted electrical power is essential.
SM MARINE SERVICE™ supplies New, Reconditioned, and Fully Tested SELCO T4800-31 Load Sharers, together with synchronizing modules, generator controllers, power management system (PMS) spare parts, repair services, refurbishment, calibration, and worldwide technical support.

Marine Generator Load Sharing & Synchronizing Controller
SM MARINE SERVICE™ maintains stock of SELCO generator automation equipment, load-sharing controllers, synchronizers, protection relays, power management modules, communication boards, spare parts, and marine electrical automation systems. We provide worldwide supply, repair, calibration, refurbishment, troubleshooting, and technical support for shipowners, ship managers, shipyards, and marine engineers.
The SELCO T4800-31 Load Sharer is a microprocessor-based generator load sharing and synchronization controller designed for marine diesel generator power management systems. It enables multiple generators to operate safely in parallel by automatically balancing active load, maintaining system frequency, and protecting generators from reverse power and overload conditions.
The controller continuously communicates with generator governors, circuit breakers, and the Power Management System (PMS), ensuring stable electrical power throughout the vessel. It is widely installed on commercial ships, offshore platforms, naval vessels, and industrial marine power plants.
The T4800-31 continuously supervises generator operating conditions and automatically distributes electrical load.
The controller continuously monitors:
Before closing the generator circuit breaker, the controller compares:
Only when synchronization conditions are correct does the controller allow breaker closing.
Once generators are operating in parallel, the T4800 automatically:
If abnormal conditions occur, the controller activates protective functions such as:
This protects both generators and the vessel's electrical distribution system.
The SELCO T4800-31 is commonly installed on:
After extended service, engineers may encounter:
If faults occur, engineers should inspect:
Recommended maintenance includes:
Routine maintenance helps maintain reliable generator operation and minimizes the risk of onboard power failures.
The SELCO T4800-31 continues to be widely used because it provides:
It automatically synchronizes generators, shares electrical load, supervises generator frequency, and protects against reverse power during parallel operation.
Yes. The T4800-31 is specifically designed for parallel operation of multiple diesel generators in marine Power Management Systems.
Yes. Most failures involving the PCB, relay circuits, power supply, synchronization circuits, communication interfaces, and governor outputs can be repaired by experienced marine automation engineers.
Yes. SM MARINE SERVICE™ supplies:
Yes. We provide complete inspection, repair, refurbishment, testing, calibration, troubleshooting, commissioning support, and worldwide technical assistance.
