Detailed description

Koormuse jaotur Mastervolt BI 1203-S on robustne ja töökindel lahendus, mis on loodud 12/24 VDC süsteemidega varustatud laevade energia juhtimise optimeerimiseks. See võimaldab efektiivselt jaotada laadimisvoolu, mis pärineb generaatorilt või laadijalt, kuni kolmele iseseisvale akupargile, samal ajal tagades nende elektrilise eraldatuse, et vältida üksteise tühjendamist. See mudel sobib hästi paigaldusteks, mis vajavad stabiilset toiteallikat ja akude suuremat kaitset.

Tehnoloogia ja jõudlus

Kuuludes Mastervolti BI-seeria hulka, kasutab BI 1203-S diodipõhist tehnoloogiat. See erineb mudelitest ilma sufiksita "S" pooljuhtdioodide kompenseerimise integreeritud funktsiooni poolest. See funktsioon on oluline, sest see kompenseerib automaatselt pinge langust (umbes 0,6 V), mis on diodidele omane, kui jaoturit kasutatakse Mastervolt Mass laadijatega või Alpha Pro laaderegulaatoritega. See tagab, et akud saavad täis pinget laadimiseks, optimeerides nii nende eluiga kui ka jõudlust. Võrreldes teiste Mastervolti lahendustega, nagu näiteks Charge Mate, mis keskendub kahe akupargi ühendamisele/lõpetamisele, või Battery Watch, mis pakub akude jälgimist ja peamise lüliti funktsiooni, suudab BI 1203-S töötada maksimaalse väljundvooluga 80 A laadijale ja 120 A generaatorile, sisendpingega 6–50 VDC, ning maandusisolatsiooniga üle 500 V 60 Hz juures.

Konstruktsioon ja paigaldus

Mastervolt BI 1203-S on kompaktse konstruktsiooniga, mõõtmetega 207 x 140 x 80 mm ja kaaluga 1,3 kg, mis lihtsustab paigaldamist kitsastesse ruumidesse pardal. Selle konstruktsioon on mõeldud merekeskkonnale: see on valmistatud täielikult korrosioonikindlatest materjalidest, alumiiniumist soojusdissipaatori ja sünteetilistes materjalides kapseldatud elektroonikakomponentidega. See robustsus tagab ereda vastupidavuse kõige nõudlikumate mereolude vastu, töötemperatuurivahemikuga -40 kuni +120 °C. Paigaldamine on lihtsustatud sünteetiliste plaatidega otste küljes, kus asuvad terminalid, ning tugevate keermeliste ühenditega mutrite ja lukustusalusplaatidega, mis tagavad töökindla ja kiire ühenduse. Mudelite "S" puhul on vooluallika sondi (sense-ühendus) ühendamine oluline, et aktiveerida pinge languse automaatne kompenseerimine.

« Technical analysis: Mastervolt BI 1203-S load distributor with diode compensation »

The Mastervolt BI 1203-S is a proven solution for managing multiple battery banks on board. As a conventional diode isolator, it provides essential electrical isolation between up to three battery groups, preventing mutual discharge. Its ability to handle a maximum alternator current of 120 A and a charger current of 80 A makes it suitable for medium to large marine electrical systems.

The key advantage of the "S" version lies in its integrated compensation diode. This feature is crucial for maintaining optimal charging voltage across each battery bank. When paired with Mastervolt Mass chargers or Alpha Pro charge controllers, the BI 1203-S automatically compensates for the voltage drop (approximately 0.6 V) inherent in diodes, ensuring batteries receive their full charging voltage without manual adjustment of the source.

Its robust construction, featuring an aluminum heat sink and encapsulated components, ensures excellent durability and resistance to corrosive marine environments. Installation is straightforward with clear terminals and reliable threaded connectors, though connecting the "sense" line is mandatory to fully utilize voltage compensation on "S" models. It is essential to respect cable distances and cross-sections to optimize performance and minimize heat buildup under high loads.

Frequently asked questions

Need help? Contact us

What is the Mastervolt BI 1203-S load distributor?

The Mastervolt BI 1203-S load distributor is a robust and reliable device designed to optimize energy management aboard vessels. It efficiently distributes charging current from an alternator or charger to multiple independent battery banks.

What is the main function of the BI 1203-S charge distributor?

The primary function of the BI 1203-S battery distributor is to split the charging current between different batteries or battery banks with the same nominal voltage. It ensures electrical isolation between batteries, preventing them from discharging each other.

What is the difference between the BI 1203-S model and a BI splitter without the "S" suffix?

The main difference lies in the integration of a compensation diode on models with the suffix "S" (such as the BI 1203-S). This diode automatically compensates for the voltage drop (approximately 0.6 to 0.7 V) inherent to diodes, ensuring that batteries receive their full charging voltage, especially when paired with Mastervolt Mass chargers or Alpha Pro charge regulators.

How many battery banks can the BI 1203-S battery distributor manage?

The Mastervolt BI 1203-S battery distributor is designed to manage up to three independent battery banks.

What technology is used in the BI 1203-S load distributor?

The BI 1203-S load distributor is based on conventional diode technology.

What are the physical dimensions of the BI 1203-S load distributor?

The dimensions of the BI 1203-S load distributor are as follows:

Height: 207 mm (8.1 inches)Width: 140 mm (5.5 inches)Depth: 80 mm (3.1 inches)

What is the weight of the BI 1203-S load distributor?

The BI 1203-S load distributor weighs 1.3 kg (2.9 lb).

What is the maximum output current for a charger and an alternator with the BI 1203-S?

The BI 1203-S distributor can handle a maximum output current of:

80 A for a battery charger. 120 A for an alternator.

What are the materials used to manufacture the BI 1203-S splitter?

The BI 1203-S splitter is made from materials fully resistant to corrosion. It features an aluminum heat sink and its electronic components are encapsulated in synthetic materials for enhanced robustness and durability.

Where should I mount the BI 1203-S charge distributor for optimal performance?

For optimal performance, the BI 1203-S charge distributor must be installed as close as possible to the power source (charger or alternator) and the batteries. It should be mounted in a well-ventilated environment, preferably on a flat metal surface, with the cooling fins positioned vertically. This helps dissipate the heat generated by high currents.

What safety precautions should I take before installing the splitter?

Before any installation, ensure the power source output is switched off (dead). Also check that no loads are connected to the batteries to avoid any hazardous situation.

How to connect the positive terminals of the batteries and the power source to the busbar?

Connections are made as follows:

Connect the positive output of the power source (charger or alternator) to terminal A of the busbar. Terminal A is the longest bolt.Connect the positive connections of the battery banks to terminals 1, 2 and 3 of the busbar, respectively.

How to connect the compensation probe (sense) on the BI 1203-S splitter?

For models with a compensation diode such as the BI 1203-S, connect the probe (sense) from the current source to the S terminal of the splitter. The S terminal is the thinnest bolt. This connection enables automatic regulation of the output voltage.

Should the negative connections of the batteries and power source be connected to the busbar?

No, the negative connections of battery banks and power sources (charger or alternator) must be connected directly to a common ground point, not to the load distribution busbar.

With which Mastervolt equipment is the BI 1203-S splitter specifically designed to operate?

The BI 1203-S splitter is specifically designed to operate optimally with Mastervolt Mass battery chargers and Alpha Pro charge regulators. These devices feature an automatic voltage drop compensation function that leverages the BI 1203-S's compensation diode.
