Detailed description

El convertidor DC Master 48/12-6 de Mastervolt està dissenyat per proporcionar una tensió de sortida estable de 12V a partir d’un parc de bateries de 48V. Ideal per a aplicacions marines i industrials, aquest convertidor reductor de tensió no aïllat garanteix una alimentació fiable per als equips electrònics sensibles que funcionen amb 12V, amb una capacitat de 6A en contínua i pics de fins a 8A durant dos minuts. Gràcies a la seva tecnologia de commutació d’alta qualitat, assegura una conversió d’energia eficient amb una dissipació tèrmica perfectament controlada.

Prestacions elèctriques i integració

Accepta una tensió d’entrada que va de 40 a 62 V DC, aquest model lliura una tensió nominal estabilitzada de 13,6 V, protegint així els instruments de navegació, els llums LED o els sistemes de comunicació de les fluctuacions de tensió del bord. Amb un consum en buit inferior a 100 mA, el DC Master 48/12-6 preserva l’autonomia del vostre parc de bateries de 48V. A diferència dels models aïllats de la gamma Mastervolt que separen els circuits galvànicament, aquesta versió no aïllada permet beneficiar-se d’un format ultracompacte (89 x 87 x 50 mm) i d’un pes reduït de 415 grams, ideal per a espais restringits on la massa comuna no planteja problemes de bucle de terra.

Disseny robust per a l’entorn marí

La carcassa d’alumini anoditzat i policarbonat armat amb fibra de vidre confereix al convertidor una excel·lent resistència mecànica i una dissipació tèrmica passiva eficient, sense ventilador, garantint un funcionament totalment silenciós. Certificat IP53, resisteix a les projeccions d’aigua i a la pols. La seva instal·lació es simplifica mitjançant un suport de muntatge dedicat sobre el qual la unitat es clipa, i mitjançant connexions elèctriques de tipus Faston per a un cablejat ràpid i segur. Per a necessitats energètiques superiors en una xarxa de 48V, és possible orientar-se cap als models DC Master 48/12-9A o 48/12-20A de la mateixa gamma.

Expert review

« Thermal reliability and compactness for 48V to 12V step-down »

The Mastervolt DC Master 48/12-6 converter perfectly addresses the integration issues of standard 12V equipment (VHF, chartplotters, lighting) on vessels or industrial vehicles equipped with 48V service batteries. Although this is a non-isolated model, its conversion topology ensures excellent output voltage stability at 13.6 V, even during significant input voltage variations (up to 62 V). Its extremely compact design and clip-mounting system make installation particularly easy in confined spaces or dense electrical panels. The absence of a fan (natural convection cooling via the aluminum housing) is a major asset for long-term reliability, eliminating the risk of mechanical failures due to marine fouling. This is a pragmatic and extremely reliable choice for continuous loads up to 6A (82W).

Frequently Asked Questions

Need help? Contact us

What is the Mastervolt DC Master 48/12-6 converter used for?

It converts the voltage of a 48V battery bank into a stable 12V output (13.6V nominal). It is ideal for powering your 12V equipment (onboard electronics, lighting, communication) from a 48V system.

What power output does this converter deliver?

It delivers a continuous current of 6A (82W) and can provide a peak current of 8A (109W) for a maximum duration of two minutes.

Is this model galvanically isolated?

No, the 48/12-6 model (reference 81400600) is a non-isolated converter. This means it has a common ground, which is perfectly suitable for installations where the ground loop is not an issue and allows for a more compact design.

Does the device emit noise during operation?

No, it operates completely silently. Cooling is achieved naturally (passive thermal dissipation) thanks to its aluminium housing, with no fan required.

What is the accepted input voltage range?

To deliver its full output power, the inverter accepts an input voltage between 40 and 62 V DC. It tolerates voltages ranging from 0 to 65 V DC without sustaining physical damage.

How to mount the converter on my boat?

Installation is straightforward thanks to the included mounting bracket. Simply secure the bracket (clip) with the provided screws onto a flat surface, then snap the converter into place.

Which items are included in the box?

The DC Master converter is supplied with all necessary accessories:

A mounting bracket (clip)Mounting screwsFaston terminals for electrical connection

Do we need to install a fuse with this converter?

Yes, for safety reasons, it is imperative to install a fuse on the positive wiring, and to place it as close as possible to the 48V battery.

What is the wiring order during installation?

During installation, you must first connect the two input cables (coming from the 48V battery). Only then can you connect the output cables to your 12V equipment.

What type of connectors should I use for the wiring?

The input and output connections on the device use Faston-type terminals, which are in fact supplied with the converter.

Where should I install the converter?

It is strongly recommended to choose a cool, dry, and well-ventilated location to ensure optimal heat dissipation and extend the device's lifespan.

Can I use this converter to power sensitive electronic devices?

Yes. The output voltage is stabilized at 13.6 V, which effectively protects your navigation instruments, communication systems, or LED lighting from voltage fluctuations on board.

Can this converter be used on a 24V battery system?

No, this specific model (48/12-6) is designed exclusively for a nominal input voltage of 48V. For a 24V system, you should look at the 24/12 range from Mastervolt.

Is the converter suitable for use outside of marine applications?

Yes, although it is very popular in marine applications, its robustness and certifications (CE, E-mark) make it perfectly suitable for recreational vehicles (motorhomes) and industrial applications.

Should power be disconnected during installation?

Yes, it is essential to ensure the power source output is turned off and no consumers are connected to the batteries during installation to avoid any electrical risk.

Can the output voltage vary depending on the load?

No, the converter is equipped with a stabilization function. It maintains a constant output voltage of 13.6 V, regardless of load variations, as long as you remain within its capacity limits (6A continuous).
