Detailed description

The MasterBus Repeater Mastervolt (reference 77031100) is a critical component designed to optimize and extend the range of MasterBus communication networks, a proprietary protocol from Mastervolt dedicated to intelligent energy management aboard vessels. This device doubles the maximum length of your MasterBus network, ensuring the integrity and reliability of data transmission in extended installations where direct wiring solutions reach their performance limits.

Advanced Technical Features

The MasterBus Repeater integrates two primary functions: data refresh and network power supply. For data refresh, it offers three operational modes: "Off" mode, which splits the MasterBus into two separate networks without data transfer, "On" mode, which refreshes all data passing through the repeater, and "Smart" mode, which refreshes data only if the receiver is located on the other side of the repeater, thereby minimizing unnecessary traffic. This capability is crucial for complex installations, preventing signal degradation over long distances. The repeater is recommended for cable lengths exceeding 250 m with fewer than 10 devices, 150 m with fewer than 25 devices, or 100 m with fewer than 50 connected devices. It is powered via the MasterBus or an external 8–35 V DC source.

Power Management and System Integration

In addition to data refresh, the MasterBus Repeater contributes to powering the MasterBus network. It offers a choice between "Low" power mode (12 V, 8 V at full load) and "High" power mode (16 V, 8 V at full load). Both modes deliver the same power output, but the "Low" mode prioritizes "High powering" devices in case of need, which is particularly beneficial for small, unmonitored battery banks. These features are configurable via a MasterView display or the MasterAdjust software. With compact dimensions of 66 x 78 x 32 mm and a weight of just 0.09 kg, it integrates discreetly and can be mounted on a 30 mm DIN rail. Its IP21 protection rating makes it suitable for protected environments. Unlike NMEA 2000 repeaters that extend a generic data bus, the MasterBus Repeater is specifically optimized for the Mastervolt protocol, ensuring maximum compatibility and performance within the brand’s energy management systems, such as those integrating Mastervolt chargers, inverters, and lithium batteries.

Expert opinion

Pol CONIN

Digital Manager

« Optimization and extension of the MasterBus network »

The Mastervolt MasterBus Repeater is a critical component for any large-scale MasterBus installation. Its ability to refresh the signal is essential for maintaining data integrity over cable lengths exceeding standard recommendations, preventing communication errors that could compromise the reliability of the energy management system. As an expert installer, we value its dual function as both a data repeater and a power injector. The 'Low' and 'High' power modes offer valuable flexibility to optimize power distribution across the bus, particularly in setups with multiple battery banks. Its IP21 protection rating makes it suitable for installations in protected environments, which is standard for this type of network electronic equipment. The DIN rail mounting option simplifies integration into electrical panels or technical enclosures. This is an indispensable link for ensuring the performance and scalability of complex MasterBus architectures.

What is the MasterBus Repeater from Mastervolt used for?

The MasterBus Repeater from Mastervolt (reference 77031100) is a device designed to optimize and extend the range of MasterBus communication networks. It doubles the maximum network length, ensuring data transmission integrity and reliability over extended installations.

What are the main functions of the MasterBus Repeater?

The MasterBus Repeater integrates two main functions: data refresh and MasterBus network power supply. These functions are essential for maintaining network performance over long distances and with many connected devices.

What are the different data refresh modes available?

The MasterBus Repeater offers three data refresh modes:

"Off" Mode: The MasterBus is split into two separate networks with no data transfer."On" Mode: All data passing through the repeater is refreshed."Smart" Mode: Data is refreshed only if the receiver is located on the opposite side of the repeater, minimizing unnecessary traffic.

What power supply is required for the MasterBus Repeater?

The MasterBus Repeater can be powered via MasterBus itself or by an external 8 to 35 V DC source.

When is it recommended to use a MasterBus Repeater?

A MasterBus Repeater should be used for cable lengths exceeding:

250 m with fewer than 10 connected devices.150 m with fewer than 25 connected devices.100 m with fewer than 50 connected devices.

What are the dimensions and weight of the MasterBus Repeater?

The MasterBus Repeater has dimensions of 66 x 78 x 32 mm (H x W x D) and weighs approximately 0.09 kg (90 grams).

What is the ingress protection rating (IP) of the MasterBus Repeater?
