Detailed description

Namijenjen preciznom nadzoru istosmjernih električnih sustava, ampérmetar M2 DC tvrtke BLUE SEA (model 1832) digitalni je uređaj koji može mjeriti i prikazivati istosmjernu struju na dva neovisna kruga. Ovaj uređaj nudi mjerni raspon od -500 do 500A s priloženim shuntom od 500A, te podržava programabilne omjere shuntova za nadzor do 5000A, osiguravajući prilagodljivost različitim konfiguracijama napajanja na brodu.

Prikaz i Napredne Funkcije

Opremljen svijetlim i automatski prigušivim OLED zaslonom veličine 55mm x 28mm, ampérmetar M2 DC osigurava optimalnu čitljivost pri širokim kutovima gledanja i kroz polarizirane naočale. Uređaj ima funkciju alarmiranja pri visokoj struji, podešljivu i zvučnu na 80dB, koja omogućuje upozoravanje korisnika u slučaju prekoračenja postavljenih granica. Dodatna funkcionalnost je izolirani MOSFET relej od 500mA, koji omogućuje upravljanje vanjskim krugovima ovisno o izmjerenim vrijednostima, dodajući sloj automatizacije upravljanju energijom.

Robusna Konstrukcija i Postavljanje

Ampérmetar M2 DC radi na ulaznom naponu od 7 do 70V DC i ima minimalnu potrošnju električne energije od 0,3 W, maksimalnu 1,00 W. Njegova konstrukcija odgovara normi zaštite IP66, što ga čini otpornim na prašinu i jake mlazove vode ili teško more, što je ključno u morskom okruženju. U usporedbi s tradicionalnim ampérmetrima ili osnovnijim rješenjima, M2 se ističe mogućnošću nadzora dva kruga, naprednim OLED zaslonom i funkcijama alarmiranja i releja, postavljajući ga kao sveobuhvatno i svestrano rješenje za nadzor istosmjerne struje na brodovima koji zahtijevaju detaljno upravljanje električnom energijom. Dio je serije digitalnih monitora M2 tvrtke BLUE SEA, poznate po integriranju naprednih funkcionalnosti u kompaktan oblik.

« Accurate 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-current DC consumers. Its ability to simultaneously monitor two circuits 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 enables rapid identification of imbalances or abnormal consumption, contributing to battery longevity and the reliability of the electrical system.

The key advantage of this ammeter lies in its flexibility with 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 shunt positioning within the circuit is required 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 M2 DC ammeter by BLUE SEA?

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 amperage 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's screen?

The M2 DC ammeter's OLED screen measures 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 electrical consumption of the M2 DC ammeter?

The electrical 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 IP66 waterproofing standards. This means it is resistant to dust and powerful water jets or heavy seas, making it perfectly suited for a marine environment.

How does the M2 DC ammeter's high current alarm work?

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

What is the purpose of the built-in 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 feature 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.

Can the ammeter be used with shunts of different ratings?

Yes, the M2 DC ammeter supports programmable shunt ratios. This allows it to be used with shunts of different ratings 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 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, thereby maximizing 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 beyond 500A?

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