Description détaillée

Alternatorul Alpha Compact 28/150 de la Mastervolt este o soluție de încărcare de înaltă performanță, concepută pentru navele echipate cu parcuri de baterii de mare capacitate care funcționează la 24V. Cu un curent de ieșire de 150 amperi, acest model asigură o încărcare rapidă și optimă, chiar și la turații reduse ale motorului.

Design compact și raport putere/greutate

Deosebindu-se de seria Alpha clasică prin gabaritul redus, gama Alpha Compact a fost dezvoltată pentru a se integra în spațiile motorizate restricționate. Cu o greutate de doar 7,9 kg, acest model 28/150 oferă o densitate energetică excepțională. Arhitectura sa internă favorizează o răcire termică eficientă, permițând susținerea unor curenți de încărcare ridicați în mod continuu, fără supraîncălzirea generatorului.

Integrare sistem și compatibilitate

Acest model specific este livrat fără scripete, oferind astfel flexibilitatea tehnică necesară pentru a adapta un scripete personalizat, precum o curea cu mai multe caneluri (serpentină), perfect aliniată cu configurația mecanică a motorului dumneavoastră. Pentru a exploata pe deplin capacitățile sale și pentru a asigura protecția bateriilor (în special a parcurilor de baterii litiu-ion), acest alternator trebuie asociat obligatoriu cu un regulator de încărcare extern, precum Mastervolt Alpha Pro, care garantează un ciclu de încărcare inteligent în 3 etape și o protecție termică riguroasă a sistemului.

Avis de l'expert

« Maximum power density for high-capacity battery banks »

The Mastervolt Alpha Compact 28/150 alternator is a must-have choice for modern vessels, particularly those equipped with Lithium-Ion battery banks requiring very high acceptance currents. Its ability to deliver 150A at 24V in such a compact format (7.9 kg) solves the space constraints of today’s engine rooms. Being supplied without a pulley is a genuine technical advantage for professional installers, allowing precise adaptation of a serpentine belt drive—essential for transferring the required mechanical power without risk of slippage. Paired with the Alpha Pro regulator, it turns the propulsion engine into a highly efficient and secure DC power generator.
