Detailed description

Mastervoltov DC Master 48/12-6 pretvarač napona namijenjen je za stabilan izlazni napon od 12V iz baterijskog sustava od 48V. Idealno rješenje za pomorske i industrijske primjene, ovaj neizolirani snižavajući pretvarač osigurava pouzdano napajanje osjetljivih elektroničkih uređaja koji rade na 12V, s kontinuiranim opterećenjem od 6A i vršnim opterećenjem do 8A tijekom dvije minute. Zahvaljujući visokokvalitetnoj tehnologiji prekidanja, osigurava učinkovitu pretvorbu energije s odličnom toplinskom regulacijom.

Električna svojstva i integracija

Prihvaća ulazni napon od 40 do 62 V DC, a isporučuje stabilizirani nazivni napon od 13,6 V, štiteći vaše navigacijske instrumente, LED rasvjetu ili komunikacijske sustave od naponskih fluktuacija na brodu. S potrošnjom u praznom hodu manjom od 100 mA, DC Master 48/12-6 štedi autonomiju vašeg 48V baterijskog sustava. Za razliku od izoliranih modela iz Mastervoltove palete koji galvanički odvajaju krugove, ova verzija omogućuje ultrakompaktan oblik (89 x 87 x 50 mm) i smanjenu težinu od 415 grama, što je idealno za ograničene prostore gdje zajednička masa ne stvara probleme s uzemljenjem.

Robusna izvedba za morsku okolinu

Kućište od anodiziranog aluminija i pojačanog polikarbonata s staklenim vlaknima osigurava izvanrednu mehaničku otpornost i učinkovito pasivno hlađenje bez ventilatora, što jamči potpuno tihi rad. Certificiran IP53, otporan je na prskanje vodom i prašinu. Instalacija je olakšana zahvaljujući namjenskoj montažnoj podlozi na koju se jedinica učvršćuje klipnim mehanizmom, te električnim priključcima tipa Faston za brzo i sigurno ožičenje. Za veće energetske potrebe na 48V mreži, možete razmotriti modele DC Master 48/12-9A ili 48/12-20A iz iste serije.

« 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 battery banks. Although it 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 format and clip-mounting system make installation particularly easy in confined spaces or dense electrical panels. The absence of a fan (cooling via natural convection through the aluminum housing) is a major advantage for long-term reliability, eliminating risks of mechanical failures due to marine fouling. It is a pragmatic and highly 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 from a 48V battery bank to a stable 12V output (13.6V nominal). It is ideal for powering your 12V equipment (onboard electronics, lighting, communication) from a 48V system.

What is the output power of this converter?

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 ground loops are not an issue and allows for a more compact format.

Does the device emit noise during operation?

No, it operates completely silently. Cooling is handled naturally (passive thermal dissipation) thanks to its aluminum 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 from 0 to 65 V DC without sustaining physical damage.

How to mount the converter on board my boat?

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

What items are included in the box?

The DC Master converter comes with all necessary accessories:

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

Is a fuse required with this converter?

Yes, for safety reasons, a fuse must be installed on the positive wiring, placed as close as possible to the 48V battery.

What is the wiring order during installation?

During installation, 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 device's input and output connections use Faston-type terminals, which are included 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 must choose a model from the Mastervolt 24/12 range.

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 loads 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).
