Battery shunt 200 A, 50 mV

A battery shunt is an electrical component designed to measure direct current (DC) flowing through a circuit. It is connected in series with the battery and produces a small voltage drop proportional to the current. This voltage drop is then measured by a compatible battery monitor to calculate and display the precise amperage, enabling monitoring of the battery's charge and discharge state.

This Raymarine battery shunt is designed to handle a maximum current of 200 amperes (A). It produces a voltage drop of 50 millivolts (mV) at full load, which is the reference value for compatible battery monitors to measure current accurately.

The 200 A, 50 mV battery shunt is specifically designed to measure direct current (amperage). To measure battery voltage and temperature, additional sensors and a compatible battery monitor are required, such as those built into modern battery monitoring systems.

By providing accurate data on charge and discharge current, this shunt enables continuous and reliable monitoring of your batteries' state. This information is crucial for optimizing battery usage, identifying consumption trends, detecting potential anomalies in the electrical system, and ultimately extending the lifespan of your battery banks.

While the documentation does not provide specific IP ratings for the shunt itself, the Maretron/OctoPlex products it is compatible with are designed for marine environments and are certified to standards such as IEC60533 and IEC60945 for electrical and electronic installations on vessels. It is recommended to install it in a location protected from direct water spray.

In the OctoPlex G2-Series system, the shunt is a key component of the battery monitoring module. It measures current and transmits this information to the module, which combines this data with voltage and temperature (if additional sensors are present) to provide a complete overview of battery status. This data can then be displayed on compatible multifunction displays (MFD).

No, the 200 A, 50 mV battery shunt is a current sensor and does not include a monitoring display. It is designed to work in conjunction with a compatible battery monitor and a multifunction display (MFD) or dedicated user interface, which will display the collected data.

This shunt is compatible with modern battery monitoring systems, including those based on NMEA 2000 networks. It is specifically listed as integrable in Maretron's OctoPlex ecosystem, where it provides current data to the battery monitoring module.

Yes, this shunt is designed to be compatible with modern battery monitoring systems that integrate with NMEA 2000 networks, such as Maretron’s OctoPlex system. This means it can provide data that will then be processed and transmitted via the NMEA 2000 network by a compatible battery monitor.

Yes, the battery monitoring module of the OctoPlex system, with which this shunt is designed to operate, measures and reports 12 VDC and/or 24 VDC systems. Therefore, the shunt is suitable for both types of battery systems.

The shunt provides current data to a compatible battery monitor (such as the OctoPlex). If this battery monitor transmits data over the NMEA 2000 network, then compatible NMEA 2000 multifunction displays (MFD) from other brands should be able to display this information, provided they support the relevant Parameter Group Numbers (PGN) for battery monitoring.

Although this shunt is specifically designed and optimized for marine applications and integration with systems such as OctoPlex, a shunt is a generic component. It could technically be used in other DC current monitoring applications requiring a 200 A capacity and a 50 mV output, provided it is paired with a compatible monitor. However, it is marketed for the nautical sector.

The battery shunt must be connected in series with the circuit of the battery you wish to monitor. This means all current from the battery (both charging and discharging) must pass through the shunt for the measurement to be accurate. The voltage measurement wires of the battery monitor are then connected to the shunt terminals.

Yes, it is important to ensure that all connections are secure and that the shunt is installed in an appropriate environment. OctoPlex products (and by extension components such as the shunt) are not ignition-protected devices and must not be installed in areas with combustible vapors. It is recommended to periodically check mounting hardware and connections.

The shunt itself is a passive component that creates a voltage drop. It does not require a separate power supply. It is the battery monitor to which it is connected that will need power to read and process the shunt's data and to communicate on the NMEA 2000 network.

The shunt is a passive component with a fixed resistance value that produces 50 mV at 200 A. Calibration is typically done at the compatible battery monitor level, which reads the shunt’s voltage drop. It is essential to ensure the monitor is configured to match the shunt’s specifications (200 A, 50 mV) for accurate readings.

The battery shunt is a component of Maretron’s OctoPlex battery monitoring system, which is NMEA 2000® certified. This certification ensures that the system, and by extension its integrated components, has been tested and verified to meet critical safety criteria and to correctly implement network management and messaging.

Maretron's OctoPlex system, which this shunt is designed to work with, has several important certifications, including:

CE ApprovedIEC60533 (Electrical and electronic installations in ships)IEC60945 (Marine navigation and radiocommunication equipment and systems)Lloyd’s Type Approved (Certificate No. 10/00021)NMEA 2000® Approved (Certified, Category B)These certifications attest to the product's compliance and reliability in the marine environment.

The packaging contains the Raymarine 200 A, 50 mV battery shunt itself. The connection cables to the battery monitor and the compatible battery monitor are usually sold separately, as the shunt is a component of a larger system.

The shunt is a component that integrates into larger systems such as the OctoPlex. The technical documentation provided (e.g., the "OctoPlex Installation Guide") covers the installation of system components, including the "Battery Monitor" section where the shunt is used. It is therefore recommended to refer to the complete system installation guide for specific instructions.
