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.

The main 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.

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 batteries receive their full charging voltage, especially when paired with Mastervolt Mass chargers or Alpha Pro charge regulators.

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

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

The physical 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)

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

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

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

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.

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.

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

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.

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

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.

The BI 1203-S splitter 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.

No, the Mastervolt BI 1203-S charge splitter cannot be used in combination with a charger/inverter combo.

The Mastervolt BI 1203-S charge distributor has a two-year warranty period.
