Litherra Zenith Distribution Unit

Smart Power Distribution. Protected. Connected. Expandable.

The Litherra Zenith Distribution Unit is a smart 12V power distribution system designed to safely deliver and manage power to multiple onboard devices while maintaining full system visibility and protection. With a total system capacity of 120A and 12 individually fused outputs, the unit provides reliable power distribution to essential loads such as lighting, water pumps, televisions, heating systems, and communication equipment.

Each output is protected by a plug-in fuse, and the system provides clear alerts if a fuse has blown, allowing faults to be quickly identified and resolved. Built-in protection features guard against battery overvoltage, over-discharge, load overcurrent, and high-temperature conditions, ensuring safe and dependable system operation.

Integrated Bluetooth, RS485, and CAN communication allow real-time monitoring and load control through the Zenith system, helping simplify wiring layouts while improving overall system safety and reliability.

Zenith System Compatibility & Expansion

Like all Litherra Zenith products, the Zenith Distribution Unit is designed to operate as part of a fully integrated and expandable system. When connected to the Zenith Control Unit and display system, it allows users to monitor and control individual loads while receiving real-time system alerts, including blown fuse notifications.

The unit can be used as a standalone distribution solution or integrated into larger Zenith installations, ensuring systems can expand as power demands increase while maintaining clean, organised wiring and simplified installation architecture.
