Detailed description

Įkrovos paskirstytuvo Mastervolt BI 1203-S paskirtis – tvarkyti energijos tiekimą laivuose su 12/24 VDC sistemomis. Jis efektyviai paskirsto įkrovos srovę iš generatoriaus arba įkroviklio į iki tris nepriklausomus akumuliatorių blokus, užtikrindamas jų elektrinį atskyrimą, kad išvengti tarpusavio iškrovimo. Šis modelis tinka įrenginiams, kuriems reikalinga stabili maitinimo sistema ir didesnė akumuliatorių apsauga.

Technologija ir našumas

Priklausantis Mastervolt BI serijai, BI 1203-S naudoja įprastą diodų technologiją. Jis skiriasi nuo modelių be „S“ priedo įtraukta kompensacine diode. Ši funkcija leidžia automatiškai kompensuoti įtampos kritimą (apie 0,6 V), kuris atsiranda naudojant diodus, kai paskirstytuvas jungiamas prie Mastervolt Mass tipo įkroviklių arba Alpha Pro reguliatorių. Tai garantuoja, kad akumuliatoriai gauna pilną įkrovos įtampą, optimizuojant jų gyvavimo trukmę ir našumą. Palyginimui, kiti Mastervolt sprendimai, kaip Charge Mate, skirtas dviejų akumuliatorių jungimui/atsijungimui, o Battery Watch siūlo stebėjimo ir pagrindinio jungiklio funkcijas. BI 1203-S gali tiekti iki 80 A įkrovikliui ir 120 A generatoriaus, esant įėjimo įtampai 6–50 VDC, o įžeminimo izoliacija siekia daugiau nei 500 V esant 60 Hz.

Konstrukcija ir įrengimas

Mastervolt BI 1203-S pasižymi kompaktiška konstrukcija (207 × 140 × 80 mm) ir svoriu 1,3 kg, todėl lengvai įmontuojamas laivuose su ribotais erdvės resursais. Jis atitinka jūrinio naudojimo reikalavimus: pagamintas iš visiškai korozijai atsparių medžiagų, turi aliumininį šilumos išskirstytuvą ir elektronikos komponentus, užlietus sintetinėmis medžiagomis. Tokia konstrukcija užtikrina ilgaamžiškumą net pačiomis sudėtingiausiomis jūrinėmis sąlygomis, dirbant temperatūrose nuo -40 °C iki +120 °C. Įrengimas supaprastintas dėl sintetinių plokščių galuose su gnybtais ir tvirtų suveržiamųjų jungčių su veržlėmis bei blokuojančiomis poveržlėmis, užtikrinančiomis patikimą ir greitą jungtį. „S“ modeliams būtina prijungti jutiklį (sense-connection) prie srovės šaltinio, kad būtų aktyvuota automatinė įtampos kritimo kompensacija.

« 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-based distributor, it provides essential electrical isolation between up to three battery groups, preventing mutual discharge. With a maximum alternator current rating of 120 A and a charger current rating of 80 A, it is suitable for medium to large marine electrical systems.

The key advantage of the "S" version lies in its integrated compensation diode. This feature is critical for maintaining optimal charging voltage across each battery bank. When paired with Mastervolt Mass chargers or Alpha Pro charge regulators, the BI 1203-S automatically compensates for the approximately 0.6 V voltage drop 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, delivers 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 "S" models. It is essential to adhere to 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 charge distributor?

The Mastervolt BI 1203-S charge 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 main function of the BI 1203-S charge distributor is to split the charging current between different batteries or battery banks with the same nominal voltage. It provides 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 in 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 Mastervolt 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 are the manufacturing materials of the BI 1203-S splitter?

The BI 1203-S splitter is manufactured using 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 circuit). Also check that no loads are connected to the batteries to prevent any hazardous situations.

How to connect the positive terminals of 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 source current sense probe 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 distributor?

No, the negative connections of battery banks and the power source (charger or alternator) must be connected directly to a common ground point, not to the charge distributor.

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.
