Detailed description

Punjač baterija Mastervolt Mass 24/50-2 namijenjen je zahtjevnim morskim i mobilnim okruženjima. Isporučuje struju punjenja od 50A pri naponu od 24V te uključuje automatski proces punjenja u tri faze (3-step+) koji osigurava brzo i sigurno punjenje vaših baterijskih parkova. Za razliku od serije ChargeMaster, koja je više usmjerena na standardne nautičke instalacije, serija Mass prilagođena je intenzivnoj i profesionalnoj uporabi te nudi veću robusnost zahvaljujući kućištu tipa C2 i zaštitnom stupnju IP23.

Performanse i integracija sustava

Ovaj punjač ima dvije izlazne struje: glavni izlaz od 50A za pomoćne baterije i sekundarni izlaz od 3A namijenjen održavanju baterije za pokretanje motora. U potpunosti je kompatibilan s mrežom MasterBus, što omogućuje konfiguraciju, nadzor i centralizirano upravljanje s kompatibilnim prikazivačem. Isporučen je s temperaturnom sondom opremljenom kabelom dužine 6 metara za termalnu kompenzaciju, osiguravajući optimalan vijek trajanja vaših olovnih, gel, AGM ili litij-ionskih baterija. Instalacija zahtijeva vertikalni montažu u prozračenom prostoru s osiguranjem sigurnih spojeva u odvojenom odjeljku koji je dostupan samo kvalificiranim instalaterima.

Pouzdanost i sigurnost

Izrađen od industrijskih komponenti, punjač Mass 24/50-2 teži 4,6 kg i radi na izmjeničnoj struji od 230V (50-60Hz). Uključuje napredne zaštite protiv kratkih spojeva, inverzije polariteta i pregrijavanja te automatsko smanjenje snage iznad 40°C okolne temperature kako bi zaštitio unutarnju elektroniku. U usporedbi s konkurentima slične klase kao što je serija Centaur tvrtke Victron Energy, model Mass tvrtke Mastervolt ističe se izvorno integriranom MasterBus povezanošću i sposobnošću održavanja visoke preciznosti punjenja čak i pri jakim fluktuacijama električne mreže ili generatora.

« The industrial standard for 24V charging in marine environments »

The Mastervolt Mass 24/50-2 charger is a true benchmark for onboard electrical installations requiring industrial-grade reliability. In practice, its rugged housing and power electronics enable it to withstand the harshest engine-room environments, though it must be mounted away from direct spray (IP23). The 3-step+ algorithmic charge management, paired with the supplied temperature sensor, ensures a perfect charging curve—a critical factor for preserving high-capacity battery banks. Native integration with the MasterBus network simplifies setup and monitoring of the entire power system. The inclusion of a secondary 3A output is a strategic advantage, allowing the engine-start battery to remain on float charge without requiring an additional distribution module.

Frequently Asked Questions

Need help? Contact us

What is the Mastervolt Mass 24/50-2 charger?

Mastervolt's Mass 24/50-2 is a professional battery charger designed for the most demanding marine and mobile environments. It delivers a 50A charge current at 24V and uses a three-stage automatic charging process to ensure fast and safe recharging of your battery banks.

How many outputs does this charger have?

This model has two separate outputs:

A primary 50A output dedicated to charging the house battery bank.A secondary 3A output specifically for maintaining the starter battery.

Which battery types are compatible with this charger?

The Mass 24/50-2 charger is highly versatile. It is fully compatible with the following battery technologies:

Flooded lead-acidGelAGMLithium-ion

What is the ingress protection rating of this model?

This charger has an IP23 protection rating. This means it is protected against solid objects larger than 12.5 mm and against rainwater at angles up to 60° from the vertical, making it suitable for indoor mounting in a marine environment.

How should the Mass 24/50-2 charger be installed?

Installation must meet several criteria for optimal operation:

It must be mounted vertically, with connection cables facing downward.The space must be well-ventilated and protected from excessive moisture.It must never be installed directly above batteries to avoid corrosive gas emissions.

Is the charger supplied with a temperature sensor?

Yes, the charger is supplied as standard with a temperature sensor featuring a 6-metre cable. This sensor automatically adjusts the charging voltage based on battery temperature, optimizing battery lifespan.

Is this charger compatible with the MasterBus network?

Yes, it is fully compatible with the MasterBus communication network. This allows you to configure, monitor, and control the charger centrally from a compatible display. A MasterBus terminator is also included in the box.

What is the required input voltage to power the device?

The charger operates on a standard 230V AC power supply, with a frequency range of 50 to 60 Hz.

What happens if the ambient temperature in the cabin is very high?

The charger features advanced thermal protection. If the ambient temperature exceeds 40°C, the device automatically reduces its charging power (derating) to protect its internal electronic components and prevent overheating.

Can the charger be installed in the same compartment as the batteries?

No, it is strongly discouraged to install the charger in the same enclosed compartment as the batteries. Lead-acid batteries generate potentially explosive and corrosive gases during charging, which could damage the charger's electronics.

What is the weight of this Mastervolt charger?

The charger alone has a net weight of 4.6 kg. With its complete packaging, the total weight is about 6.8 kg.

How much free space must be left around the device during installation?

To ensure sufficient airflow and proper cooling, it is essential to leave at least 10 cm of free space all around the charger.

How to check which charging phase the device is in?

The front panel of the charger is equipped with LED indicators. These lights display the device's real-time operating status and the current charging phase (Bulk, Absorption, Float).

What is the 3-step+ charging process?

The 3-step+ process is an automatic charging algorithm developed by Mastervolt. It comprises three main phases:

Bulk: Fast charge at maximum current.

Who should carry out the installation of this charger?

The charger is designed to be permanently connected to AC and DC electrical systems. Its installation and wiring must be carried out by a qualified technician or electrician, in compliance with local regulations.

Is the charger noisy during operation?

The charger uses an active ventilation system to cool its internal components. The fan may produce a slight noise when operating at full power, but its speed automatically adjusts to the cooling needs of the device.

Is an earth (ground) connection required for this charger?

Yes, it is mandatory for safety reasons. The charger must be connected to an earth (ground) conductor via the dedicated terminal on the AC input to prevent any risk of electric shock.
