Detailed description

DC pretvornik Master 48/12-6 podjetja Mastervolt je namenjen zagotavljanju stabilne izhodne napetosti 12 V iz baterijskega sistema 48 V. Idealno za morske in industrijske aplikacije, ta neizolirani DC/DC pretvornik zagotavlja zanesljiv napajalni tok za vašo občutljivo elektroniko, ki deluje na 12 V, z kontinuirnim tokom 6 A in vršnim tokom do 8 A v dveh minutah. Visokokvalitetna tehnologija preklapljanja zagotavlja učinkovito pretvorbo energije z dobro nadzorovano toploto.

Električne lastnosti in integracija

Pretvornik sprejema vhodno napetost v območju od 40 do 62 V DC in zagotavlja stabilizirano izhodno napetost 13,6 V, kar ščiti vaše navigacijske instrumente, LED razsvetljavo ali komunikacijske sisteme pred nihanjem napetosti na krovu. Z porabo v mirovanju pod 100 mA DC Master 48/12-6 ohranja avtonomijo vašega baterijskega sistema 48 V. V nasprotju z izoliranimi modeli iz Mastervoltove palete, ki galvansko ločijo tokove, ta neizolirana različica omogoča izredno kompaktno izvedbo (89 x 87 x 50 mm) in zmanjšano težo 415 gramov, kar je idealno za omejene prostore, kjer skupna masa ne predstavlja problema zaradi zemeljske zanke.

Robustna izvedba za morsko okolje

Ohišje iz anodiranega aluminija in oklepljenega polikarbonata zagotavlja pretvorniku odlično mehansko odpornost in pasivno odvajanje toplote, brez ventilatorja, kar zagotavlja popolnoma tihi del. Certificiran po standardu IP53, odporen je proti vodnim pršilom in prahu. Namestitev je olajšana z namenjenim montažnim držalom, na katerega se enota priklopi, ter z električnimi priključki tipa Faston za hitro in varno kabliranje. Za večje energetske potrebe na mreži 48 V lahko izberete modele DC Master 48/12-9A ali 48/12-20A iz iste palete.

« 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 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 format 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 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 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 form factor.

Does the device emit noise during operation?

No, it operates completely silently. Cooling is achieved 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 converter accepts an input voltage between 40 and 62 V DC. It tolerates voltages ranging from 0 to 65 V DC without sustaining hardware 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 on a flat surface, then snap the converter into place.

Which 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, it is mandatory to install a fuse on the positive wiring, and to place it as close as possible to the 48V battery.

What is the order for connecting the cables 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 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 must choose 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 that 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).
