Detailed description

The MasterBus 0.5m cable from Mastervolt is an essential component for building and extending your embedded power management network. Based on the CAN-bus communication protocol, the MasterBus system enables seamless integration and communication between various Mastervolt devices, such as battery chargers, inverters, energy monitors, and control interfaces. With its ultra-compact length of 0.5 meters, this cable is specifically designed to connect adjacent devices within the same electrical panel or battery bank, minimizing clutter and the risk of electromagnetic interference.

Reliability and optimized system integration

Unlike longer cables in the range (such as the 3m, 6m, or 10m versions) intended for inter-compartment connections, this 50 cm model is ideal for direct daisy-chaining between closely spaced components, such as a MasterShunt shunt and a Mastervolt Lithium-Ion battery, or between two DIN-rail mounted network interfaces. It uses high-quality standardized connectors that ensure fast and secure data transfer, essential for synchronizing power systems. Compliant with the RoHS directive (2011/65/EU) and the NEN-EN-IEC 63000:2018 design standard, it ensures optimal durability in demanding marine or mobile environments.

Expert opinion

« The essential ally for clean and interference-free network cabling »

The choice of communication cable length is often overlooked when designing a marine electrical system. This 0.5m MasterBus cable is the perfect element for daisy-chaining equipment installed side by side, such as interface modules or adjacent batteries. It prevents the creation of unnecessary cable loops that clutter cable trays and can pick up electromagnetic interference (EMI). Its certified design ensures lossless CAN-bus data transmission, essential for network responsiveness and precise synchronization of Mastervolt charge algorithms.

Frequently Asked Questions

Need help? Contact us

What is the MasterBus 0.5m cable from Mastervolt used for?

This cable is designed to connect and enable communication between Mastervolt equipment (chargers, inverters, energy monitors) within your onboard energy network using the CAN-bus communication protocol.

Is this cable compatible with equipment from other brands?

No, the MasterBus cable is specifically designed for Mastervolt's proprietary network. It is intended to connect exclusively devices compatible with the MasterBus ecosystem.

How is the cable connected to the network?

The connection is made in a daisy-chain configuration. Simply connect the cable from one device to the next using the standardized MasterBus ports on your equipment.

Does this cable require a termination resistor?

Yes, as with any MasterBus network, both ends of your device chain must be terminated with a MasterBus Terminator, regardless of the cable length between devices.

Can I use this cable to connect a MasterShunt to a Mastervolt battery?

Yes. This 0.5m cable is particularly recommended for direct bridging between very close components, such as a MasterShunt and a Mastervolt Lithium-Ion battery.

Is the MasterBus cable directly compatible with an NMEA 2000 network?

The cable itself uses Mastervolt's proprietary CAN-bus protocol. To connect your MasterBus network to a NMEA 2000 network, you will need a specific interface (MasterBus NMEA 2000 Interface) in addition to this cable.

Is this component suitable for a marine environment?

Yes, this cable is designed for optimal durability in demanding marine and mobile environments, ensuring reliable connections despite vibrations and harsh onboard conditions.

Which environmental standards does this cable comply with?

This MasterBus cable strictly complies with the RoHS directive (2011/65/EU) and the NEN-EN-IEC 63000:2018 design standard regarding the restriction of hazardous substances in electrical equipment.

What is the weight of this cable?

The MasterBus cable is 0.5 meters long, extremely lightweight, with a total packaged weight of just 28 grams (0.028 kg).

Do you need specific tools to install this cable?

No specific tool is required. The connectors clip directly and easily into the MasterBus ports of your devices, using a plug-and-play system.

Can this communication cable be routed next to power cables?

Although the cable is designed to minimize interference, it is still recommended, during installation, to physically separate communication cables from high-power cables to ensure optimal data signal.

Does this cable transmit data only?

The MasterBus network transmits both communication data and low-power electrical supply. This allows small control interfaces or displays to be powered directly via the communication cable.

How many devices can this cable connect?

A MasterBus cable has two ends and is used to connect exactly two adjacent devices within your network chain.

Which types of Mastervolt devices can I connect with this cable?

You can connect all Mastervolt devices in the MasterBus ecosystem equipped with MasterBus ports: battery chargers, inverters, combined systems, energy monitors, shunts, and various control interfaces.

Is the cable supplied with its connectors?

Yes, the cable is ready to use. It is supplied with its high-quality connectors already fitted and secured at both ends.

What does daisy-chaining mean?

A daisy-chain setup means devices are connected one after another. This cable links device A to device B, then another cable links device B to device C, forming a continuous communication chain.

Can this cable be used for DIN rail-mounted interfaces?

Absolutely. Its short 50 cm length is perfectly suited for cleanly connecting two network interfaces or Mastervolt modules mounted side by side on a DIN rail in your electrical panel.

Which communication protocol does this cable use?

The cable uses the CAN-bus communication protocol, which forms the reliable and fast foundation of the MasterBus system for power system synchronization.
