Detailed description

Mastervolt DC Master 48/12-6 įtampos keitiklis skirtas tiekti stabilią 12V įtampą iš 48V baterijų komplekto. Idealiai tinka jūrinėms ir pramoninėms aplikacijoms. Šis neizoliuotas įtampos mažinimo keitiklis užtikrina patikimą maitinimą jūsų jautriems 12V įrenginiams, pasižymėdamas 6A nuolatine galia ir 8A srovės šuoliais (iki 2 minučių). Naudojant aukštos kokybės komutacinę technologiją, jis užtikrina efektyvų energijos keitimą su gerai kontroliuojamu šilumos išsiskyrimu.

Elektrinės charakteristikos ir integracija

Keitiklis priima 40–62V DC įėjimo įtampą ir tiekia stabilizuotą 13,6V nominalią įtampą, apsaugodamas jūsų navigacijos įrenginius, šviestuvus LED ar ryšio sistemas nuo įtampos svyravimų. Tuščios eigos srovė mažesnė nei 100 mA, todėl DC Master 48/12-6 tausoja 48V baterijų komplekto energiją. Skirtingai nuo Mastervolt izoliuotų modelių, kurie galvaniškai atskiria grandines, ši neizoliuota versija leidžia pasiekti itin kompaktišką dydį (89 x 87 x 50 mm) ir sumažintą 415 g masę, kas idealu erdviškai ribotose zonose, kai bendras potencialas nesukelia grunto kilpos problemų.

Robusti dizainas jūrinei aplinkai

Aliuminio anodizuoto korpuso ir stiklo pluošto armuoto polikarbonato konstrukcija suteikia keitikliui puikią mechaninę tvirtumą ir efektyvų pasyvų šilumos išsklaidymą be ventiliatoriaus, garantuojant visiškai tylų darbą. IP53 sertifikatas užtikrina atsparumą vandens purslams ir dulkioms. Įrengimas supaprastintas specialia montavimo atrama, į kurią įrenginys įsispraudžia, bei Faston tipo elektros jungtimis greitam ir saugiam kabelių prijungimui. Esant didesniems energijos poreikiams 48V tinkle, galima rinktis kitus tos pačios serijos modelius: DC Master 48/12-9A arba 48/12-20A.

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 battery banks. Although this is a non-isolated model, its conversion topology ensures excellent output voltage stability at 13.6 V, even with 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 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 design.

Does the device emit noise during operation?

No, it operates completely silently. Cooling is achieved naturally (passive thermal dissipation) via its aluminum housing, with no need for 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 from 0 to 65 V DC without sustaining physical damage.

How to mount the converter aboard 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 simply clip the converter onto it.

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

Is a fuse required with this converter?

Yes, for safety reasons, it is essential to install a fuse on the positive wiring, placed 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 (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 cut during installation?

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

Can the output voltage vary with the load?

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