Rozváděč nabíjení BI 1203-S

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.

The primary 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 between batteries, preventing them from discharging each other.

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 controllers.

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

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

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

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

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

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

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

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.

For optimal performance, the BI 1203-S load distributor must be installed as close as possible to the power source (charger or alternator) and the batteries. It must 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 that the power source output is disconnected (power off). Also check that no consumers 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 current source probe (sense) to the S terminal of the busbar. The S terminal is the thinnest bolt. This connection enables automatic regulation of the output voltage.

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

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

No, the Mastervolt BI 1203-S load distributor cannot be used in combination with a charger/inverter.

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