Detailed description

MASTERVOLT ChargeMaster Plus 24/20-3 yra išmanusis automatinis baterijų įkroviklis, skirtas teikti universalų ir patikimą įkrovos sprendimą jūrinių ir mobilių aplinkų sąlygomis. Priklausantis ChargeMaster Plus serijai, šis 24V/20A modelis išsiskiria savo „Baterijos geriausio draugo“ architektūra, leidžiančia vienu metu ir saugiai įkrauti iki trijų skirtingų tipų ir dydžių baterijų, įskaitant švino rūgšties (gelio, AGM, užpildytas) ir litio jonų baterijas, naudojant 3+ žingsnių intelektualų įkrovos procesą. Jis taip pat integruoja priešplūdinimo funkciją, kuri užkerta kelią mažų baterijų perkrovai, ir leidžia nustatyti individualius įkrovos profilius.

Jungtis ir sistemos integracija

Šis įkroviklis veikia kaip energijos sistemos centras dėl savo išsamaus ryšio sąsajų. Jis pilnai suderinamas su MasterBus, CZone ir NMEA2000 tinklais, užtikrinant tikslų ir detalią prijungtų baterijų įkrovos būsenos, įtampos ir temperatūros stebėjimą. Ši jungtis užtikrina sklandų integravimą su kitais Mastervolt įrenginiais, tokiais kaip MasterShunt ar sistemos ekranai, realiam reguliavimui ir optimizuotai veiklai. Skirtingai nuo paprastesnių įkroviklių, ChargeMaster Plus 24/20-3 neapsiriboja tik baterijų įkrovimu – jis intelektualiai valdo energijos sistemą.

Efektyvumas ir patvarumas

Gebėdamas apdoroti įėjimo įtampą nuo 80 iki 275 V ir dažnius 50/60 Hz, ChargeMaster Plus 24/20-3 užtikrina efektyvią įkrovą visame pasaulyje. Jis siūlo galvaninį atskyrimą ir temperatūros kompensaciją (jį įskaitant) tiksliai ir saugiai įkrovai. Jo budėjimo režimo energijos sąnaudos yra mažesnės nei 2 mA (MasterBus išjungtas). Suprojektuotas ekstremalioms sąlygoms, jis atlaiko aplinkos temperatūras nuo -25 °C iki 80 °C (su ribojimu virš 40 °C) ir turi IP23 apsaugos lygį montuojant vertikaliai. Vario ventiliatoriaus aušinimo sistema užtikrina labai žemą triukšmo lygį. Jis turi daugiau apsaugų nuo perkaitimo, perkrovos, trumpojo jungimo, aukštos/žemos baterijos įtampos ir uždegimo, garantuojančių įrenginio patikimumą. Kompaktiškos jo dimensijos (291 x 210 x 105 mm) ir 2,5 kg svoris leidžia lengviau ir paprasčiau jį integruoti nei ankstesnius tos pačios kategorijos modelius.

« Multi-battery load management in marine environments »

The MASTERVOLT ChargeMaster Plus 24/20-3 is a high-performance charging solution essential for modern marine and mobile electrical systems. Its ability to charge up to three battery banks simultaneously, 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) attest to 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.
