Detailed description

Deilarinn Mastervolt BI 1203-S er traust og áreiðanlegt tæki, hannað til að bæta viðskiptum rafmagni um borð í skipum með 12/24 VDC kerfi. Hann dreifir rafmagni frá rafmagnsöflun (t.d. rafmagnsöflunaraðferð eða hleðslutæki) til allt að þriggja óháðra rafhlöðunarhópa, með því að tryggja rafmagns einangrun til að koma í veg fyrir að rafhlöður losi spennu hvor í aðra. Þessi gerð er í lagi fyrir uppsetningar sem krefjast stöðugs afls og aukinna verndar rafhlöðanna.

Tækni og frammistaða

Meðlimur í BI-flokki Mastervolt, BI 1203-S, notar hefðbundna díóðutækni. Hann greinist frá gerðum án "S" viðskeytis með innbyggðri jafnvægisdíóðu. Þessi eiginleiki er mikilvægur þar sem hann sjálfvirkt jafnar spennufallið (um 0,6 V) sem stafar af díóðum þegar deilarinn er tengdur við rafhlöðuhleðslutæki Mastervolt Mass eða stýritæki Alpha Pro. Þetta tryggir að rafhlöðurnar fá fulla hleðsluspennu, sem eykur líftíma og frammistöðu þeirra. Aðrar lausnir frá Mastervolt eins og Charge Mate eru einungis fyrir tengingu/aftengingu tveggja rafhlöðanna, en Battery Watch gefur yfirsýn og hefur aðalrofafstöðu. BI 1203-S hefur hámarks útflæði 80 A fyrir hleðslutæki og 120 A fyrir rafmagnsöflun, með inntaksspennu 6 til 50 VDC, og einangrun frá jörðu meira en 500V við 60Hz.

Hönnun og uppsetning

Mastervolt BI 1203-S er með þétta hönnun með stærðum 207 x 140 x 80 mm og þyngd 1,3 kg, sem auðveldar innsetningu í þröngum rýmum um borð. Byggingin er hönnuð fyrir sjávarumhverfi: hann er framleiddur úr efnum sem eru algjörlega ónæm fyrir tæringu, með varmaskipti úr áli og rafeindadeildum umluktar plastefnum. Þessi styrkur tryggir framúrskarandi endingargetu gagnvart erfiðustu sjávarumhverfum, með starfshita frá -40 til +120°C. Uppsetning er einföld með plastplötum á endunum með skautin og sterka gengju með festingum og undirskotsskífur sem tryggja traga og fljótlega tengingu. Fyrir gerðir með "S" er tenging á mælingaröð (sense-connection) frá spennugjafa nauðsynleg til að virkja sjálfvirka jafnvægisleiðréttingu spennufalls.

« 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 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 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, guarantees excellent durability and resistance to corrosive marine environments. Installation is simplified by clear terminals and reliable threaded connectors, although 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 load distributor?

The Mastervolt BI 1203-S load distributor is a robust and reliable device designed to optimize energy management onboard 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 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 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 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 lbs).

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 made from materials fully resistant to corrosion. It includes 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 disconnected (powered off). Also check that no loads are connected to the batteries to prevent any hazardous situations.

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 sense probe on the BI 1203-S busbar?

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

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

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 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.
