Șunt ampermetru 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 an 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 flows through it, which is then interpreted by a measuring device.

A 450A/50mV shunt is chosen for installations requiring high-current measurement, such as 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 an energy management system to provide accurate data on current flow.

This ammeter shunt is manufactured by the BEP brand.

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

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

To ensure interference-free signal transmission and optimal accuracy, installing this shunt requires the use of shielded twisted-pair cable.

The minimum recommended cable size for the signal cable to be used with this shunt is 0.25 mm².

Using shielded twisted-pair cable is critical to maintaining 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 generally placed along 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 type of cable to ensure the accuracy and reliability of the system. For proper and safe installation, it is often recommended to use 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 vibration. This ensures the longevity and reliability of the shunt and the entire measurement system under harsh conditions.

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

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

This shunt can work with any battery monitor or energy management system capable of interpreting a standardised 50mV input signal at full load. The 50mV 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 12V, 24V or other), as long as the current flowing 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 role is to create a voltage drop proportional to the current flowing through it, which is then measured by an external device.

Yes, provided that the battery monitor or energy management system from another brand is designed to accept a 50mV input signal at full load, this shunt can be used. The 50mV 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 done at the battery monitor or energy management system to which the shunt is connected, to correctly interpret the 50mV signal.
