Převodník nabíječka Mac Plus 48/12-50

The Mastervolt Mac Plus 48/12-50 is a bidirectional DC-DC converter-charger. It is designed to convert a 48V battery voltage into a stabilized 12V output with a 50A current. It can also operate in reverse to charge a 48V battery from a 12V system, or a 12V starter battery from a 48V system. It can be used as a three-stage battery charger or as a stabilized DC power supply.

This converter is ideal for situations where the main power system is 48V, but where equipment requires a 12V power supply. It can also charge a 48V lithium service battery bank while sailing or driving, or charge a 12V starter battery when connected to the network.

Yes, the Mac Plus 48/12-50 is a bidirectional DC-DC converter/charger. By default, it converts 48V to 12V. However, the current flow direction can be reversed via MasterBus configuration, the CZone circuit, or a remote switch, allowing, for example, charging a 12V starter battery from a 48V system.

The Mac Plus 48/12-50 can function as a three-stage battery charger. This feature enables optimized battery charging, extending their lifespan and ensuring full capacity.

The Mac Plus 48/12-50 model uses an input voltage of 48V and provides an output voltage of 12V. The nominal output current is 50A.

The IP23 protection rating means the Mac Plus is protected against solid objects larger than 12.5 mm (protection against finger access) and against water spray up to 60° from the vertical. This indicates it is suitable for humid environments but must be installed away from direct water spray.

The Mac Plus includes protections against reverse polarity, short circuits, and overheating. It is also designed to minimize the risks of electric shocks and fire if installation and usage instructions are followed.

The Mac Plus must be mounted with four M5 screws on a flat and solid surface. A minimum clearance of 10 cm (4 inches) on each side is required to ensure adequate airflow and prevent overheating. It must not be mounted directly above batteries that may release corrosive fumes.

For the 48/12-50 model, the recommended minimum cable size is 6 mm² (AWG 9) for the high-voltage side (48V) and 16 mm² (AWG 6) for the low-voltage side (12V). If bidirectional functionality is used, it is advisable to select a larger cable size for the low-voltage side.

Installation and any intervention on the Mac Plus must be carried out only by a qualified, certified, and trained technician or electrician, in accordance with local standards and regulations in force.

No, the Mac Plus can only be used in electrical installations with a common negative ground.

The Mac Plus must not be exposed to rain, snow, spray, excessive humidity, excessive pollution, or condensation conditions. It must also not be installed in poorly ventilated areas or locations with a risk of gas or dust explosions.

Yes, the Mac Plus 48/12-50 is designed to integrate with MasterBus and CZone networks. This integration enables real-time monitoring of voltages, currents, and alarms, as well as advanced configuration via events.

Yes, the Mac Plus has a dedicated input (pins 5 and 6 on the accessory connector) for a battery temperature probe. A probe is included in the delivery.

Yes, the Mac Plus has a voltage drop compensation function, accessible via pins 1 and 2 of the accessory connector. This ensures stable voltage at the battery terminals despite long cable lengths.

The Mac Plus is designed to work with lead-acid batteries and can charge a 48V lithium service battery bank. It is crucial never to charge a frozen battery and not to use the Mac Plus to charge non-rechargeable batteries. Battery parameters can be configured via the DIP switches or MasterBus/CZone.

Mastervolt offers a two-year product warranty on the Mac Plus, starting from the date of purchase.

For the warranty to be valid, the product must be installed and used in accordance with the manual instructions. Removing the identification label will also void the warranty.

The warranty is limited to the cost of repair and/or replacement of the product. Labor and shipping costs are not covered by this warranty.
