ChargeMaster Plus 24/20-3

The ChargeMaster Plus 24/20-3 is an advanced 24V, 20A automatic battery charger. It is designed to charge up to three batteries simultaneously, even if they are of different types and sizes. It features a "Battery's Best Friend" architecture and a 3-step+ intelligent charging process. It is also compatible with MasterBus, CZone, and NMEA2000 networks.

Yes, the ChargeMaster Plus 24/20-3 is designed with the "Battery's Best Friend" architecture, allowing it to safely charge up to three batteries of different types and sizes simultaneously. It supports lead-acid batteries (gel, AGM, flooded) and lithium-ion batteries.

The charger uses a 3-step+ intelligent charging process (IUoUo). This process optimizes charging for Gel, AGM, flooded, and lithium-ion batteries. It also includes a pre-floating function to prevent overcharging of small batteries and allows setting custom charge profiles.

The dimensions of the ChargeMaster Plus 24/20-3 are 291 x 210 x 105 mm (11.5 x 8.3 inches). Its weight is 2.5 kg (5.5 lb).

The ChargeMaster Plus 24/20-3 can operate within an ambient temperature range from -25 °C to 80 °C (-13 to 176 °F). However, output power decreases above 40 °C (80% power at 60°C).

The charger is equipped with multiple safety protections, including overheating, overcharging, short circuits, high and low battery voltages, and an ignition protection.

Yes, the ChargeMaster Plus 24/20-3 is equipped with a variable-speed fan for cooling. This enhanced cooling technology delivers very low noise levels across the entire power range.

Yes, thanks to its MasterBus, CZone and NMEA 2000 communication interfaces, the ChargeMaster Plus can provide detailed information on the power supply, charger performance, as well as the voltage and temperature of connected batteries. This enables system monitoring and configuration via a compatible display.

The pre-floating function is a feature of the ChargeMaster Plus 24/20-3 charging process. It prevents the risk of overcharging small batteries when multiple batteries of different sizes are charged simultaneously.

Yes, the ChargeMaster Plus 24/20-3 has galvanic isolation.

The ChargeMaster Plus 24/20-3 is fully compatible with MasterBus, CZone, and NMEA 2000 communication networks. These interfaces enable precise control and detailed monitoring of charge status and battery conditions.

The ChargeMaster Plus 24/20-3 can handle nominal input voltages of 120/240 V (with an operating range of 80 to 275 V) and frequencies of 50/60 Hz. This allows it to operate efficiently worldwide.

Yes, the ChargeMaster Plus 24/20-3 can communicate directly with Mastervolt MLI Ultra Lithium-ion batteries for real-time settings and optimal performance. The Lithium-ion charge profile is included.

Yes, the ChargeMaster Plus models can be used as convenient standalone battery chargers ready for use. They can also be integrated into a complete MasterBus or CZone system.

The charger must be installed in a well-ventilated area. It must never be placed directly above a charging battery, nor in an enclosed or unventilated space, as this could cause it to overheat and corrode due to battery gases. The mounting is vertical.

Installing the ChargeMaster Plus requires correctly installed, undamaged, and properly sized wiring for the charger's AC and DC amperage. The wiring must comply with applicable local standards and regulations and must be performed by qualified personnel.

Yes, the ChargeMaster Plus must be equipped with an earth conductor connected to the AC earth terminal. Earthing and all other wiring must comply with local standards and regulations.

The ChargeMaster Plus 24/20-3 has an IP23 ingress protection rating, meaning it is protected against solid objects larger than 12.5 mm and against rain falling up to 60° from the vertical. It is designed for vertical mounting.

The ChargeMaster Plus 24/20-3 comes with a two-year product warranty from the date of purchase. This warranty is valid provided the product is installed and used in accordance with the manual's instructions.
