Detailed description

Razdeljevalnik toka Mastervolt BI 1203-S je robustna in zanesljiva rešitev, zasnovana za optimizacijo upravljanja energije na plovilih opremljenih z 12/24 VDC sistemi. Omogoča učinkovito distribucijo polnilskega toka iz alternatorja ali polnilnika do največ treh samostojnih baterijskih parkov, hkrati zagotavlja njihovo električno izolacijo, da prepreči medsebojno izpraznitev. Ta model je idealen za naprave, ki zahtevajo stabilno napajanje in dodatno zaščito baterij.

Tehnologija in zmogljivost

V okviru serije BI podjetja Mastervolt, BI 1203-S uporablja konvencionalno diodno tehnologijo. Razlikuje se od modelov brez priponke »S« po vgrajeni kompenzacijski diodi. Ta funkcija je ključna, saj avtomatsko kompenzira padanje napetosti (približno 0,6 V), ki je značilno za diode, ko je razdeljevalnik povezan z baterijskimi polnilniki Mastervolt Mass ali regulatorji polnjenja Alpha Pro. Tako se zagotavlja, da baterije prejemajo svojo polno polnilno napetost, kar podaljšuje njihov življenjski vek in izboljšuje zmogljivost. V primerjavi z drugimi rešitvami Mastervolt kot je Charge Mate (ki se osredotoča na povezovanje/prekinjanje dveh baterij) ali Battery Watch (ki ponuja nadzor in funkcijo glavnega stikalnika), BI 1203-S omogoča maksimalni izhodni tok 80 A za polnilnik in 120 A za alternator, z vhodno napetostjo od 6 do 50 VDC in električno izolacijo proti masi nad 500 V pri 60 Hz.

Konstrukcija in namestitev

Mastervolt BI 1203-S ima kompaktno konstrukcijo z dimenzijami 207 x 140 x 80 mm in težo 1,3 kg, kar olajša vgradnjo v omejen prostor na plovilu. Njegova konstrukcija je prilagojena morskemu okolju: izdelan je iz materialov, ki so popolnoma odporni na korozijo, ima aluminijasto hladilno telo in elektronske komponente, zalite v sintetična materiala. Ta robustnost zagotavlja izjemno trajnost v najzahtevnejših morskih pogojih, z delovnim temperaturnim območjem od -40 do +120 °C. Namestitev je olajšana z sintetičnimi ploščami na koncih z priključki in trdnimi navojnimi konektorji z maticami in zaviralnimi podložkami, ki zagotavljajo zanesljivo in hitro povezavo. Za modele »S« je povezava sondnega vhoda (sense-connection) iz vira toka bistvena za aktivacijo avtomatske kompenzacije padanja napetosti.

« 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 aboard. As a conventional diode-based distributor, it ensures 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 significant 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 enables automatic compensation of the voltage drop (approximately 0.6 V) inherent to 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, guarantees excellent durability and resistance to corrosive marine environments. Installation is straightforward thanks to clear terminals and reliable threaded connectors, though connecting the "sense" line is mandatory to fully utilize voltage compensation on the "S" models. It is essential to adhere to cable distances and cross-sections to optimize performance and minimize heating 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 primary function of the BI 1203-S load distributor?

The primary function of the BI 1203-S load distributor is to split the charging current between different batteries or battery banks with the same nominal voltage. It ensures electrical isolation of the 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 "S" suffix (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 controllers.

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 splitter can handle a maximum output current of:

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

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

The BI 1203-S splitter is made from fully corrosion-resistant materials. It features an aluminium 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 current 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 circuit). Also check that no loads are connected to the batteries to prevent any hazardous situation.

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

For models with a sense diode such as the BI 1203-S, connect the sense probe 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 busbar.

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

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