Mass 24/100 Charger

The Mass 24/100 charger delivers a powerful output current of 100A at 24V. It is specifically designed to quickly and safely recharge large-capacity battery banks.

Yes, this device maintains its full charging power up to an ambient temperature of 40°C. Beyond that, it applies a safe thermal derating of 2.5% per additional degree and can operate up to 80°C.

To ensure a safe installation with no voltage drop on the 24/100 model, it is recommended to use:

A 50 mm² section for cable lengths under 3 meters.

A 70 mm² section for distances between 3 and 6 meters.

Yes. The charger is directly compatible with the MasterBus protocol, allowing you to integrate it easily into a centralized energy management network for real-time monitoring.

The charger is housed in a robust aluminum casing (type C3). Its dimensions are 420 x 318 x 130 mm with a total weight of 7.7 kg.

No, this charger has an IP23 protection rating. It must be installed in a well-ventilated location, protected from rain, snow, spray, and excessive dust.

The exclusive Current Control function regulates the charger's power consumption. It prevents the unintended tripping of shore power or generator fuses, even in the event of an input voltage drop.

The charger is delivered as standard with a battery temperature probe fitted with a 6-metre cable, essential for optimising the charging cycle based on battery heat.

Yes, the Mass 24/100 charger is fully compatible with Lithium-ion technology. It features a specific setting (activated via DIP switch 5) to adapt its algorithm to this chemistry.

Yes, the device allows parallel switching of multiple units. This is very useful for multiplying the total charging capacity on board vessels with high power consumption.

A diode splitter typically causes a voltage drop of about 0.6V. This charger automatically compensates for this loss by simply activating DIP switch 4 (Diode enabled function).

The charger is designed for a nominal input voltage of 230V AC (frequency 50-60Hz). It is highly tolerant and accepts a voltage range from 180 to 265V.

Yes, this model delivers excellent energy efficiency of 89 %, optimizing energy conversion and minimizing heat losses.

Yes, it is equipped with a dry-contact alarm relay (maximum switching current of 1A). It can be configured in standard or continuous mode to control external safety equipment.

Absolutely. A specific setting for traction battery charging is provided. Simply activate DIP switch 2 to adjust the charge voltages (Bulk and Absorption) to the requirements of traction batteries.

To properly secure the DC input cables (to the batteries), use a 13 mm socket wrench. A 2 mm flathead screwdriver will also be useful for the sense terminal.

Designed for professional environments, it meets the strictest marine standards. It is certified CE, ABYC A-31, IEC60945, RRR and RMRS, ensuring total reliability for offshore navigation.

Some Gel/AGM batteries require a higher float voltage. You can increase this to 27.6V by setting DIP switch 3 to "On".

When operating at full power (to deliver its 100A), the charger's maximum power consumption from the AC mains is 3500W.

Yes, for safety reasons, it is mandatory to include a DC fuse holder with an appropriately rated fuse on the positive cable connecting the charger to the battery bank.
