Detailed description

MASTERVOLT ChargeMaster Plus 24/20-3 je napredni samodejni polnilec baterij, zasnovan za zagotavljanje vsestranske in zanesljive rešitve za polnjenje v morskih in mobilnih okoljih. V sklopu serije ChargeMaster Plus se ta model 24V/20A odlikuje z arhitekturo »Battery's Best Friend«, ki omogoča hkrati varno polnjenje do treh baterij različnih tipov in velikosti, vključno z baterijami s svinčenimi kislinami (gel, AGM, poplavljene) in litij-ionskimi, s pomočjo inteligentnega procesa polnjenja v 3+ korakih. Vključen je tudi funkcija predplavljenja za preprečevanje prekomernega polnjenja manjših baterij ter možnost nastavljanja prilagojenih profilov polnjenja.

Povezljivost in vključevanje v sistem

Ta polnilec deluje kot osrednji element energetskega sistema zaradi svojih celovitih komunikacijskih vmesnikov. V celoti je združljiv z omrežji MasterBus, CZone in NMEA2000, kar omogoča natančno kontrolo in podrobno spremljanje stanja polnjenja, napetosti in temperature povezanih baterij. Ta povezljivost zagotavlja brezhibno vključevanje z drugimi napravami Mastervolt, kot so MasterShunt ali sistemski zasloni, za realnočasovne prilagoditve in optimizirano delovanje. Za razliko od osnovnejših polnilcev ChargeMaster Plus 24/20-3 ne le polnijo, temveč pametno usklajujejo energetski management.

Zmogljivost in robustnost

Z sposobnostjo obvladovanja vhodnih napetosti od 80 do 275 V in frekvenc 50/60 Hz zagotavlja ChargeMaster Plus 24/20-3 učinkovito polnjenje po vsem svetu. Omogoča galvansko izolacijo in kompenzacijo temperature (vključena sonda) za natančno in varno polnjenje. Poraba v mirovanju je manjša od 2 mA (MasterBus onemogočen). Zasnovan za ekstremne razmere, odporen je na okolne temperature od -25 °C do 80 °C (z zmanjšanjem moči nad 40 °C) in ima stopnjo zaščite IP23 za navpični montaž. Sistem hlajenja z variabilnim ventilatorjem zagotavlja zelo nizko raven hrupa. Ima večplastno zaščito pred pregrevanjem, prekomernim polnjenjem, kratkim stikom, visokimi/ nizkimi napetostmi baterij in vžigom, kar zagotavlja zanesljivost sistema. Kompaktne dimenzije (291 x 210 x 105 mm) in težo 2,5 kg ga naredijo lažjega in lažjega za vključevanje v primerjavi s predhodnimi modeli v svoji kategoriji.

« 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 NMEA 2000 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 state via a MasterShunt, for example), which is rarely the case with more basic chargers. With an IP23 protection rating and an extended operating temperature range (-25 °C to 80 °C), it demonstrates 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.
