Mastervolt Mass 24/15-2 Battery Charger - 230 V 50/60 Hz

The Mastervolt Mass 24/15-2 charger delivers a nominal voltage of 24 V and a total charging current of 15 A at 28.5 V.

Yes, the charger is equipped with a second 3 A charging output. This output is designed for maintaining a small secondary battery, such as a start battery.

The Mastervolt Mass 24/15-2 charger is compatible with a wide range of battery types, including Gel, AGM, flooded (lead-acid), and Lithium Ion batteries.

Yes, this charger is specifically designed for demanding marine and mobile applications. It features a lightweight housing made of stainless steel and anodized aluminum, with internal components coated for protection against moisture and condensation. It is also designed to withstand vibrations and shocks.

The charger can operate within an ambient temperature range of 0 to 60°C (32 to 140°F). It maintains its full output power up to 40°C (104°F), after which power reduction is applied to manage internal heat.

The Mastervolt Mass 24/15-2 charger can charge deeply discharged batteries thanks to its specific charging characteristic.

Yes, the charger is compatible with the MasterBus system. Each MasterBus device is equipped with two data ports to form a local network. The charger has a MasterBus power supply capacity.

The Mastervolt Mass 24/15-2 charger weighs 3.3 kg.

The Mastervolt Mass 24/15-2 charger complies with the following standards and certifications: CE, ABYC A-31, RRR, and RMRS.

Yes, the charger maintains its full output power up to an ambient temperature of 40°C. Above this temperature, power output is reduced to protect the device and maintain its efficiency.

The Mass charger should be installed in a well-ventilated space protected from rain, snow, spray, steam, bilge moisture, and dust.

The minimum recommended toolkit includes:

A 13 mm socket wrench for securing DC input cables (battery).A Phillips screwdriver for opening the Mass charger connection area.A 2 mm flathead screwdriver for the sense terminal.

If a battery isolator is used, causing a 0.6 Volt voltage drop, this drop can be compensated by setting DIP-switch 4 to the "On" position (Diode enabled).

Yes, a battery temperature sensor with cable (6 meters) and plug is included with the charger. This sensor optimizes charging based on battery temperature.

The charger has four DIP switches for specific settings:

DIP switch 1 (Force Float): Sets the float charge voltage to 26.5 V. DIP switch 2 (Traction setting): Increases the voltage during bulk and absorption phases for traction batteries. DIP switch 3: Increases the float voltage to 27.6 V for certain Gel/AGM batteries. DIP switch 4 (Diode setting): Compensates for a voltage drop of +0.6 V if a battery isolator is used.

The front panel of the charger has indicator lights to show its operating status:

A green LED (LED 6) indicates normal operation, while a red LED indicates a fault condition. Combinations of LEDs (LED 1 to 5) indicate the different stages of the charging cycle (BULK, ABSORPTION, FLOAT). LEDs (LED 9 to 13) indicate the charging current in percentage (0-5%, 5-25%, etc.). A green LED (LED 7) indicates MasterBus communication.

Yes, the charger is equipped with a dry-contact alarm relay (floating potential). The alarm function has two modes: standard (factory setting) and DC alarm mode (continuous mode).

Yes, the charger is designed to operate with an input frequency of 50/60 Hz ± 5 Hz, making it compatible with most global electrical grids.

Yes, the Mastervolt Mass 24/15-2 charger can be configured for traction battery charging. It has a specific setting via DIP switch 2, which adds +0.7 V during the bulk phase and +0.4 V during absorption for 24 V batteries.
