Detailed description

Mastervolti DC Master 48/12-6 alaldur on mõeldud andma stabiilset 12 V väljundpinget 48 V akupargi toitel. Sobib hästi mere- ja tööstusrakendusteks, see mitteisolatsiooniline alaldur tagab töökindla toitevarustuse 12 V seadmetele, mille pidev voolutarve on 6 A ja lühiajaline kuni 8 A (2 minutit). Kõrgekvaliteedilise lülitustehnoloogia tõttu tagab see efektiivse energia muundamise ja hästi kontrollitud soojusemissiooni.

Elektrilised näitajad ja integreerimine

Sisendpinge vahemik 40–62 V DC, väljundpinge 13,6 V. Kaitseb navigatsiooniseadmeid, LED-valgustust ja sidesüsteeme pinge kõikumise eest. Tühikäigul tarbitav vool alla 100 mA, mis säilitab 48 V akupargi autonoomsuse. Erinevalt Mastervolti isolatsioonilistest mudelitest, mis eraldavad galvaaniliselt ahelaid, võimaldab see mitteisolatsiooniline versioon kasutada ultrakompaktset korpust (89 × 87 × 50 mm) ja kaalu 415 grammi, mis sobib hästi piiratud ruumi korral, kui ühine maandus ei põhjusta maandussilmusi.

Merenduseks vastupidav konstruktsioon

Anooditud alumiiniumist ja klaasfiberiga tugevdatud polükarbonaadist korpus tagab mehaanilise vastupidavuse ja passiivse soojus hajutamise ilma ventilaatorita, tagades täiesti vaikse töö. IP53 sertifikaat kaitseb vee ja tolmu eest. Kergesti paigaldatav spetsiaalse kinnitusega, mis võimaldab kiiret ja turvalist ühendamist Faston-tüüpi ühendustega. Suuremate energiatarvetega 48 V võrgus võib valida sama seeria DC Master 48/12-9A või 48/12-20A mudelid.

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

The Mastervolt DC Master 48/12-6 converter perfectly addresses the integration challenges 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 fluctuations (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 (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. 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 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 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 the ground loop is not an issue and allows for a more compact format.

Does the device emit noise during operation?

No, it operates completely silently. Cooling is achieved naturally (passive heat dissipation) thanks to its aluminum housing, without requiring a fan.

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 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 on a flat surface, then snap the converter onto it.

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, 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 cable connection 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 wiring?

The input and output connections on the device are made using Faston-type terminals, which are also 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?

Absolutely. 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 cut 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 prevent electrical hazards.

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).
