ChargeMaster Plus 24/40-3 Converter Charger

The Mastervolt ChargeMaster Plus 24/40-3 is a next-generation all-in-one battery charger. It is designed to simplify and optimize marine and mobile electrical systems by integrating multiple functions into a single device, reducing installation complexity and cost. It efficiently and safely charges various battery combinations.

The ChargeMaster Plus 24/40-3 integrates several unique features:

The 'Best Friend' design allows charging any combination of two or three batteries (lithium-ion, gel, AGM), regardless of size or voltage.The automatic recovery mode restores deeply discharged batteries.The multi-voltage function enables charging a 12 V starter battery within a 24 V system without additional components.The priority charging redirects available power to the most discharged battery for accelerated recharge.The smart input allows charging all three batteries from a single alternator.

The Mastervolt ChargeMaster Plus 24/40-3 provides a nominal output voltage of 24 V. The maximum output current for the primary output is 40 A. For the Smart In-/Output, output voltages are 12 V or 24 V, with adjustable output current from 5-10 A at 12 V and 5-20 A at 24 V.

The ChargeMaster Plus 24/40-3 is a multi-charger capable of managing up to three battery outputs. Its 'Best Friend' design allows it to charge two or three batteries simultaneously, even if they are of different types and voltages.

Yes, the ChargeMaster Plus 24/40-3 is designed for universal charging. It operates within a very wide input range of 80–275 V AC and frequencies of 35–70 Hz, allowing it to be used with all AC voltages and frequencies worldwide. It is resistant to significant voltage spikes and high temperatures.

Yes, the ChargeMaster Plus 24/40-3 includes a VSR (Voltage Sensitive Relay). This feature eliminates the need for additional equipment and ensures optimal energy distribution to the batteries, simplifying system installation.

The ChargeMaster Plus 24/40-3 has the following dimensions:

Height: 384 mm (15.1 inches)Width: 250 mm (9.8 inches)Depth: 127 mm (5.0 inches)Its weight is 5.9 kg (13.0 lbs).

The ChargeMaster Plus 24/40-3 includes multiple protections to ensure system and battery safety, including:

Overheat protection
Overcharge protection
Short-circuit protection
High and low battery voltage protection
Ignition protection

The ChargeMaster Plus 24/40-3 has an ambient operating temperature range of -25 °C to 80 °C (-13 to 176 °F). Note that power output is derated below 0 °C and above 40 °C.

The ChargeMaster Plus 24/40-3 uses a variable-speed fan for cooling. This ventilation system ensures the device maintains optimal operating temperature, even in demanding environments, and contributes to its performance and durability.

Yes, the ChargeMaster Plus 24/40-3 features galvanic isolation. This is a critical safety feature for marine environments, as it helps prevent electrolytic corrosion and protects against electrical shocks.

The ChargeMaster Plus 24/40-3 is compatible with a wide range of battery types. It can charge Lithium Ion, Gel, AGM, and wet (lead-acid) batteries. Its 'Best Friend' technology allows it to charge any combination of these battery types.

Yes, the ChargeMaster Plus 24/40-3 (24 V models only) has a multi-voltage function. This allows it to charge a 12 V starter battery within a 24 V installation without requiring additional components, which is a significant advantage for hybrid systems.

The ChargeMaster Plus 24/40-3 supports multiple communication interfaces for optimal system integration:

MasterBus, CZone, NMEA 2000Models with the 'CZone' option directly support CZone and NMEA 2000 without additional interfaces. Other standards such as Modbus, CANopen, and LinBus can be supported via additional interfaces.

The ChargeMaster Plus 24/40-3 is recommended for a battery capacity range of 160 to 400 Ah. This range ensures efficient charging and optimal performance for compatible battery systems.

The ChargeMaster Plus 24/40-3 has an IP23 protection rating. This means it is protected against solid objects larger than 12.5 mm and against water spray up to 60° from the vertical. It is designed for vertical mounting.

Yes, it is crucial to ensure adequate ventilation. Do not cover or obstruct the ventilation openings of the ChargeMaster Plus. Do not install it in an unventilated space, as this could cause it to overheat. It is also recommended never to place the charger directly above a charging battery, as battery gases can corrode and damage the charger.

Yes, installation of the ChargeMaster Plus and any work performed on it must be carried out only by qualified and trained personnel, in compliance with applicable local standards and regulations. Incorrect installation can result in electrocution hazards, fire risks, or damage to the product and void the warranty.

Navico Group provides a two-year product warranty on the ChargeMaster Plus 24/40-3, starting from the date of purchase. This warranty is valid provided the product is installed and used in accordance with the instructions in the supplied manual.
