Detailed description

MASTERVOLT-i ChargeMaster Plus 24/20-3 on automaatne laadija, mis on välja töötatud pakkuma mitmekülgset ja töökindlat laadimise lahendust merelises ja mobiilses keskkonnas. ChargeMaster Plus seerias kuulub see mudel 24V/20A, mis eristub oma arhitektuuriga « Battery's Best Friend », võimaldades üheaegselt ja turvaliselt laadida kuni kolme erinevat tüüpi ja suurusega akut, kaasa arvatud pli-, geeli-, AGM- ja liitiumioonakud, tänu nutikale 3-etapilisele+ laadimisprotsessile. Lisaks sisaldab see eel-laadimise funktsiooni väikeste akude ülelaadimise ennetamiseks ja võimaldab määrata isikupärastatud laadimisprofiile.

Ühenduvus ja süsteemi integreerimine

See laadija asub süsteemi energia keskmes oma täieliku kommunikatsiooniliideste tõttu. See on täielikult ühilduv MasterBus, CZone ja NMEA2000 võrkudega, võimaldades täpset kontrolli ja detailset jälgimist ühendatud akude laadimise oleku, pinge ja temperatuuri kohta. See ühenduvus tagab sujuva integreerimise teiste Mastervolt seadmetega, nagu MasterShunt või süsteemi ekraanid, võimaldades reaalajas kohandusi ja optimeeritud jõudlust. Vastupidi lihtsamatele laadijatele ei piirdu ChargeMaster Plus 24/20-3 lihtsalt akude laadimisega, vaid korraldab energia juhtimist nutikalt.

Jõudlus ja vastupidavus

Võimaldades sisendpingeid 80-st 275 V-ni ja sagedusi 50/60 Hz, tagab ChargeMaster Plus 24/20-3 efektiivse laadimise üle maailma. See pakub galvaanilist eraldust ja temperatuuri kompenseerimist (kaasas olev sond), tagades täpse ja turvalise laadimise. Ooteoleku tarbimine on alla 2 mA (MasterBus välja lülitatud). Kõrgete tingimuste jaoks välja töötatud, talub see -25 °C kuni 80 °C keskkonna temperatuure (alates 40 °C-st toimub de-rating) ning omab IP23 kaitsetaset püstise paigalduse jaoks. Vario ventilaatoriga jahutussüsteem tagab väga madala müra taseme. See on varustatud mitmete kaitsefunktsioonidega ülekuumaldamise, ülelaadimise, lühise, kõrge/madala pinge ja süütamise vastu, tagades paigalduse töökindluse. Kompaktsed mõõtmed (291 x 210 x 105 mm) ja kaal 2,5 kg teevad selle kergemaks ja lihtsamaks eelnevate mudelitega võrreldes.

« Multi-battery load management in marine environments »

The MASTERVOLT ChargeMaster Plus 24/20-3 is a high-performance battery charging solution essential for modern marine and mobile electrical systems. Its ability to simultaneously charge up to three battery banks, including lithium-ion, with tailored profiles and temperature compensation minimizes the risks of undercharging or overcharging, thereby extending battery life. Native integration with MasterBus, CZone, and NMEA2000 networks is a major strategic advantage, providing centralized monitoring and advanced automation of energy systems. This connectivity enables the charger to respond optimally to system conditions (load, temperature, battery status via a MasterShunt for example), which is rarely the case with more basic chargers. Its IP23 protection rating and extended operating temperature range (-25 °C to 80 °C) demonstrate a robust design suited to harsh environmental constraints. For professional installation, the ChargeMaster Plus 24/20-3 offers flexibility and reliability that set it apart from simpler solutions, justifying its position in demanding systems where performance and safety are paramount.
