Aquest dispositiu ofereix un rang de mesura de -500 a 500A amb el shunt de 500A inclòs, i admet relacions de shunt programables per a un monitoratge fins a 5000A, assegurant una adaptabilitat a diverses configuracions de potència a bord.

Visualització i Funcionalitats Avançades

Equipat amb una pantalla OLED de 55mm x 28mm, brillant i amb regulació automàtica de la lluminositat, l’amperímetre M2 DC garanteix una llegibilitat òptima sota àngles de visió amplis i amb ulleres polaritzades. L’aparell integra una funció d’alarma de corrent elevat, regulable i audible a 80dB, que permet alertar l’usuari en cas de superar els llindars definits. Una funcionalitat addicional és el relé MOSFET aïllat de 500mA, que ofereix la possibilitat de controlar circuits externs en funció dels valors mesurats, afegint una capa d’automatització a la gestió energètica.

Disseny Robust i Posicionament

L’amperímetre M2 DC funciona amb una tensió d’entrada de 7 a 70V DC i presenta un consum elèctric mínim de 0,3 W i màxim de 1,00 W. El seu disseny compleix amb la norma d’estanquitat IP66, fent-lo resistent a la pols i als dolls d’aigua forts o a la mar grossa, aspecte essencial en un entorn marí. Comparat amb amperímetres tradicionals o amb solucions més bàsiques, el M2 destaca per la seva capacitat de monitorar dos circuits, la seva pantalla OLED avançada i les seves funcions d’alarma i relé, posicionant-se com una solució de monitoratge DC completa i versàtil per a embarcacions que requereixen una gestió elèctrica detallada. S’inscriu en la gamma dels monitors digitals M2 de BLUE SEA, reconeguda per la integració de funcionalitats avançades en un format compacte.

« Precise and automated DC monitoring for marine systems »

The BLUE SEA M2 DC ammeter is an essential tool for energy management on board, particularly on vessels equipped with multiple battery banks or high-power DC consumers. Its ability to monitor two circuits simultaneously provides critical visibility into separate elements such as general consumption and alternator output, or the discharge of a service bank and a starter bank. This feature allows for rapid identification of imbalances or abnormal consumption, contributing to battery longevity and the reliability of the electrical system.

The main advantage of this ammeter lies in its flexibility thanks to programmable shunt ratios, allowing the instrument to adapt to systems up to 5000A. This makes it relevant for a wide range of vessels, from sailboats to motor yachts. The integration of an isolated MOSFET relay is an underrated feature; it can be configured to trigger external alarms or cut secondary circuits in case of overload or excessive consumption, providing an automated layer of safety. Installation is simplified by the included 500A shunt, but a solid understanding of ground loops and the shunt's position in the circuit is necessary to ensure accurate measurements and avoid interference. This monitor is particularly suited for owners seeking detailed and proactive monitoring of their DC system, beyond basic indicators.

Frequently Asked Questions

Need help? Contact us

What are the main functions of the BLUE SEA M2 DC ammeter?

The BLUE SEA M2 DC ammeter is designed for precise monitoring of DC electrical systems. It measures and displays DC amperage on two independent circuits. It also includes a high-current alarm function and an isolated MOSFET relay for controlling external circuits.

What is the maximum measurement range of this ammeter?

With the supplied 500A shunt, the M2 DC ammeter can measure DC current over a range of -500A to 500A. It also supports programmable shunt ratios for monitoring up to 5000A, requiring higher-capacity shunts (not included).

Is the OLED screen of the M2 DC ammeter readable in all conditions?

Yes, the device features a bright, auto-dimming OLED screen. This screen ensures optimal readability from wide viewing angles and is also readable through polarized sunglasses, which is ideal for marine environments.

What are the dimensions of the M2 DC ammeter screen?

The M2 DC ammeter has an OLED screen measuring 55mm x 28mm.

How many circuits can the M2 DC ammeter monitor simultaneously?

The M2 DC ammeter can measure and display DC amperage on two independent circuits at the same time.

What is the power consumption of the M2 DC ammeter?

The power consumption of the M2 DC ammeter is minimal, ranging from 0.3 watts minimum to 1.00 watts maximum.

Is the M2 DC ammeter water- and dust-resistant?

Yes, its design meets the IP66 waterproofing standard. This means it is resistant to dust and powerful water jets or heavy seas, making it perfectly suited to a marine environment.

How does the high current alarm on the M2 DC ammeter work?

The ammeter includes a high-current alarm function that is user-adjustable. If the measured current exceeds the user-defined thresholds, an 80 dB audible alarm is triggered to alert the user.

What is the purpose of the integrated MOSFET relay in this ammeter?

The 500 mA isolated MOSFET relay integrated into the M2 DC ammeter allows control of external circuits. It enables activation or deactivation of these circuits based on measured current values, adding an automation function to energy management.

Is the ammeter supplied with a shunt?

Yes, the M2 DC ammeter is supplied with a 500A shunt, required for current measurement.

Is it possible to use the ammeter with shunts of different capacities?

Yes, the M2 DC ammeter supports programmable shunt ratios. This allows it to be used with shunts of different capacities to monitor currents up to 5000A, beyond the included 500A shunt.

What is the required input voltage range for the M2 DC ammeter?

The M2 DC ammeter operates on an input voltage range of 7 to 70V DC.

Is the M2 DC ammeter compatible with 12V and 24V electrical systems?

Yes, the M2 DC ammeter is fully compatible with 12VDC and 24VDC electrical systems. Its wide input voltage range of 7 to 70V DC allows it to operate with these common configurations.

Are there specific considerations for installation in a marine environment?

Yes, its IP66 design makes it resistant to dust and powerful water jets, which is essential in a marine environment. For optimal installation, it is recommended to carefully follow the manufacturer's instructions to ensure proper sealing and secure electrical connections, in order to maximize its durability in this environment.

Can the M2 DC ammeter be used on systems with a voltage higher than 24V?

Yes, the M2 DC ammeter is designed to operate with an input voltage ranging from 7V DC to 70V DC. It is therefore compatible with systems having a voltage higher than 24V DC, as long as it remains within this range.

Is this ammeter compatible with battery systems exceeding 500A?

Yes, although the ammeter is supplied with a 500A shunt for measurements up to 500A, it is compatible with battery systems exceeding this capacity. The device supports programmable shunt ratios, allowing monitoring up to 5000A when using a suitable shunt (sold separately for capacities above 500A).
