Detailed description

ChargeMaster 12/25-3 Mastervoltiilt, viitenumbriga 44010250, on täielikult automaatne aku laadija, mis on mõeldud mere- ja vabaajaveokasutusele. See mudel tagab kiire ja täieliku aku laadimise sõltumata saadaolevast vahelduvvooluallikast tänu automaatsele sisetensioni tuvastamisele (90–265 V AC, 50/60 Hz). Tema 1,8 kg kaal ja kompaktsed mõõtmed (234 × 132 × 60 mm) lihtsustavad paigaldamist erinevates keskkondades. Seade on sertifitseeritud vastavalt CE, ABYC A-31, SAE J1171/ISO 8846 (süütõrje), RRR ja RMRS nõuetele, mis tagab vastavuse rahvusvahelistele standarditele.

3-etapiline+ laadimistehnoloogia

ChargeMaster 12/25-3 kasutab Mastervolti 3-etapilise+ laadimistehnoloogiat, mis optimeerib akude eluiga ja jõudlust. Protsess sisaldab järgmisi faase: BULK (kiire laadimine 0–80% maksimaalse vooluga), ABSORBTSIOON (maksimaalse pinge juures laadimine kuni 100% voolu vähendamisega 4 tunni jooksul 14,25 V juures) ja FLOAT (laadimise hoidmine 13,25 V juures (märgplii) või 13,8 V juures (Gel/AGM). Seade on ühilduv laia valikuga aku tüüpidega, sealhulgas märgplii, AGM, Gel, Spiral ja Liitiumioon (MLi) akud. Automaatne pinge- ja temperatuurikompenatsioon (kaasasoleva anduriga) reguleerib laadimise parameetreid ülelaadimise ja gaasimise vältimiseks, pikendades akude eluiga. Integreeritud mälufunktsioon vältib ülelaadimist ebastabiilse võrguvoolu korral.

Polüvalentsus ja laadimisvõimsus

Nimiväljundpingega 12 V ja laadimisvooluga 25 A 13,25 V juures suudab see laadija hallata soovitusliku mahutavusega 50–250 Ah aku parke ning laadida kuni 1000 Ah parke. ChargeMaster 12/25-3 eristub kolme võrdse väljundiga, millest igaüks suudab pakkuda 25 A. Teistest suurematest ChargeMasteri mudelitest erinevalt, millel võib olla üks peamine väljund ja kaks 10 A väljundit stardiakude jaoks, pakub see mudel voolu võrdset jaotust kõigile väljunditele. Seade suudab töödelda ka alalisvoolu püsisöötme režiimis ilma ühendatud akudeta, mis on ideaalne valgustuse või külmiku toitmiseks. Galvaaniline eraldus tagab paigalduse suurema ohutuse.

Integratsioon ja jälgimine

ChargeMaster 12/25-3 on täielikult ühilduv MasterBus võrguga, mis on Mastervolti detsentraliseeritud kommunikatsioonisüsteem. See ühilduvus võimaldab laadija ja teiste süsteemi seadmete (pingemuundur, generaator, akud) tsentraliseeritud või kaugjuhtimist. LED-indikaator paneeli ees kuvab olulisi andmeid nagu laadimisvool ja -pinge, laadimise etapp ning aku laadimise tase. Kolm nuppe võimaldavad süsteemi juhtimist. Kuigi enamik ChargeMasteri mudelitest on MasterBus ühilduvad, ei ole mudelid 12/10, 12/15-2 ja 24/6 ühendatavad ühe kaabli kaudu. Seade pakub täielikku kaitset ülekuumenemise, ülelaadimise, lühise ja kõrge/madal pinge vastu, tagades turvalise ja töökindla töö temperatuurivahemikus -25 °C kuni 60 °C.

« Technical analysis of the ChargeMaster 12/25-3: performance and MasterBus integration »

The MASTERVOLT ChargeMaster 12/25-3 is a strategic component for optimizing onboard energy management. Its 3-stage+ (Bulk, Absorption, Float) charging algorithm is proven to maximize battery lifespan, whether the batteries are lead-acid, AGM, Gel, or Lithium-ion. The automatic input voltage detection (90–265 V AC) gives this charger unrivaled global flexibility, simplifying operations during international voyages or when connected to fluctuating power sources.

MasterBus integration is a major asset, enabling centralized monitoring and control of the electrical system. This networking capability streamlines diagnostics and configuration, reducing intervention time and increasing overall reliability. The three equal 25 A outputs allow simultaneous charging for multiple battery banks, which is essential for complex installations requiring differentiated power supplies (house, start, bow thruster). With an IP23 protection rating and mechanical robustness ensured by metal connectors, this ChargeMaster is designed to withstand marine environmental stresses, ensuring stable and secure long-term performance. Its built-in protections against overcharging, short circuits, overheating, and voltage fluctuations enhance installation safety.
