Spojnica ampermetra 450 A 50 mV

An ammeter shunt is a fundamental electrical component used to measure high currents in an installation. It works by diverting a small portion of the current through a precision resistor, which generates a proportional voltage drop. This voltage is then read by a monitor or energy management system to display the total current flowing through the circuit. It is essential for monitoring electrical systems, particularly in marine installations.

This BEP shunt is designed to measure currents up to 450 amperes (450A). It outputs a 50 millivolt (50mV) signal when the maximum current of 450 amperes passes through it, which is then interpreted by a measuring device.

A 450A/50mV shunt is selected for installations requiring high-current measurement, such as on large vessels or systems with multiple consumers or generators. This model ensures accurate and reliable monitoring even under extreme loads, where lower-ampere shunts (e.g., 100A or 200A) would be insufficient and risk damage or imprecise readings.

Yes, this shunt is ideal for monitoring consumption, production, and battery state of charge. The voltage signal it generates is interpreted by a battery monitor or energy management system to provide accurate data on current flow.

This shunt ammeter is manufactured by BEP.

The product’s reference number (SKU) is LB-450-50.

Yes, the BEP 450A 50mV ammeter shunt is a fundamental component designed for current measurement in marine electrical installations.

To ensure interference-free signal transmission and optimal accuracy, this shunt requires installation with a shielded twisted-pair cable.

The minimum recommended wire size for use with this shunt is 0.25 mm².

Using a shielded twisted-pair cable is crucial to maintain the integrity of the 50mV signal. This type of cable helps prevent electromagnetic interference, ensuring accurate and reliable measurements even over potentially long distances or in noisy electromagnetic environments.

The shunt must be installed in series with the circuit whose current you wish to measure. It is typically placed on the main current path between the battery and the load or source, or between the battery bank and the energy management system to monitor total current.

Installing this shunt requires a basic understanding of electrical principles. It is essential to follow the manufacturer's instructions and use the specified cable type to ensure the accuracy and reliability of the system. For correct and safe installation, it is often recommended to hire a qualified professional.

Yes, when installing in a marine environment, it is essential to ensure all connections are securely fastened and protected against moisture, corrosion, and vibrations. This ensures the longevity and reliability of the shunt and the entire measurement system in harsh conditions.

The product information does not specify the inclusion of connection cables. It is generally necessary to purchase separately the minimum 0.25 mm² twisted pair shielded cable recommended for installation.

Yes, this shunt is ideally designed for use with battery monitoring systems and complex energy managers, such as those in BEP's CZone range.

This shunt can work with any battery monitor or energy management system capable of interpreting a standardized 50 mV input signal at full load. The 50 mV signal is an industry standard for this type of measurement.

Yes, a shunt measures current and its specification (450A/50mV) is independent of the system voltage (whether it is 12V, 24V or otherwise), as long as the current passing through the shunt does not exceed 450 amperes. It is therefore compatible with 12V and 24V systems.

A shunt is a passive component. It does not require external electrical power to operate. Its function is to create a voltage drop proportional to the current flowing through it, which is then measured by an external device.

Yes, provided the battery monitor or energy management system from another brand is designed to accept a 50 mV input signal at full load. The 50 mV signal is a common industry standard for shunts.

The shunt itself is a purely hardware component that generates an analog signal. Any necessary software configuration would be handled at the battery monitor or energy management system level to which the shunt is connected, in order to correctly interpret the 50 mV signal.
