Magic 24/12 - 20A Charger Converter

The Magic 24/12 - 20A is a versatile device primarily used to convert a 24V DC input into a stabilized 12V DC output. It can also function as a 3-stage battery charger or as a dimmer for lighting systems.

Yes, this model provides full galvanic isolation between input and output. This protects sensitive electronic equipment, such as communication or transmission gear, from electrical interference.

When configured in charger mode, it is compatible with a wide range of 12V batteries, including:

Flooded lead-acid (wet)GelAGMSpiral cellTractionLithium-ion

The converter delivers a nominal and maximum output power of 300 W, with a maximum output current of 20 A (or 16 A when used in battery charger mode).

Yes, it is perfectly possible to configure multiple converters in parallel. This feature is ideal if you have many consumers on board, as it allows you to reach capacities exceeding 100 amperes.

To ensure a secure installation, the screw terminal of the device is designed to accept cables with a maximum cross-section of 16 mm² (AWG5).

The dimmer function allows you to regulate the intensity of your 12V lighting very efficiently, without energy loss as heat. It is activated using an external momentary switch and requires specific adjustment of the internal DIP switches.

It is recommended to install it in a well-ventilated area, protected from rain, moisture, and dust. Mount it in a vertical position with cables facing downward. Caution: never install it directly above batteries to avoid damage from corrosive fumes.

Yes, although it does not have a native MasterBus port, it is compatible and can be integrated into your network via a MasterBus serial interface available as an option.

Yes, the nominal output voltage is 13.6 V, but it can be precisely adjusted between 10 V and 15 V using a PC and the MasterAdjust software.

The converter has an IP21 rating. It is protected against vertically falling water droplets but must be installed indoors in a dry environment.

You have two methods for configuration:

Use the 4 DIP switches located inside the housing for basic settings.Program it in advanced mode via a computer using the MasterAdjust software.

The unit uses high-frequency switching technology, delivering excellent efficiency above 90% at full load, with peaks up to 92%.

Yes, it is equipped with automatic overload and overheating protections. Additionally, its cooling is ensured by silent and maintenance-free variable-speed fans.

The voltage range depends on the mode of use:

In standard converter mode: 19 to 32 V.In 3-stage battery charger mode: 24 to 32 V.

Yes, for safety reasons, it is essential to include a fuse on the positive cable. This fuse must be placed as close as possible to the source battery.

When configured to recharge a 12 V battery (3-stage smart charger mode), the device delivers a maximum charging current of 16 A.

This converter is compact and lightweight. It measures 227 x 154 x 81 mm (Height x Width x Depth) and weighs 1.8 kg in total.

No, if your goal is to use it as a simple 13.6 V stabilized power supply, the factory settings are perfectly suited and you do not need to adjust the DIP switches.

Warning: the device has an internal non-replaceable input fuse. Reversing polarity (swapping positive and negative wires) will irreparably damage the converter. Always double-check your connections before powering on.
