Magic 24/24 Converter Charger - 20A

It converts a 24V DC input into a stabilized 24V DC output with full galvanic isolation. It is highly versatile and can serve as a stabilized power supply, a 3-stage battery charger, or even a dimmer for your onboard lighting system.

Yes, this model provides full galvanic isolation between input and output. This eliminates ground loops and effectively protects sensitive navigation electronics from interference.

Yes. It can function as a true three-stage (Bulk, Absorption, Float) smart battery charger to automatically charge a 24V secondary bank from your main 24V system.

When configured in stabilized continuous power supply mode, the converter delivers a constant voltage of 27.2 VDC, which is ideal for safely powering critical communication equipment.

The maximum output current of this model is 20 amperes (20A).

Yes, multiple units can be connected in parallel to increase the total available output current. You will simply need to configure the internal DIP switches of each device appropriately.

Configuration is done easily via four DIP switches located inside the device. Simply unscrew the rear cover (power off) to access them and adjust the settings according to your desired operating mode.

It has IP21 certification. It is protected against vertical drops of water droplets, but it must be installed in a well-ventilated area, protected from rain, excessive humidity, and dust.

It is recommended to install it near the batteries to limit voltage losses in the cables. However, never install it directly above them to avoid damage from corrosive sulfur fumes.

To ensure optimal heat dissipation and prevent condensation buildup, we recommend installing the unit in a vertical position with the connection cables facing downward.

Yes, it includes an alarm contact that triggers automatically in case of anomalies: undervoltage, overvoltage, overload, or short circuit. This allows the crew to be alerted or to trigger safety automations.

Yes, the Magic 24/24-20A model is designed to be configurable and usable as a dimmer for your 24V lighting systems.

Yes, by wiring the input in series with the output, it can function as a 24/48V converter. However, in this specific wiring configuration, galvanic isolation is no longer guaranteed.

Yes, it is mandatory to include a protection fuse on the positive wiring. This fuse must be placed as close as possible to the source battery to ensure the safety of your electrical installation.

The device is equipped with a non-replaceable input fuse. Reversing the positive and negative poles on the battery will irreparably damage the converter. Extreme caution is required when wiring.

Although it has very low standby power consumption, it is recommended to disconnect it from the power battery when not used for an extended period to avoid slow discharge of your battery bank.

No, the communication port on the device is not designed to connect a remote panel or a battery temperature sensor.

This port allows adjustment of various software parameters according to your specific requirements. This requires the use of dedicated Mastervolt control software and an interface.

It uses a three-stage smart charging curve:

Bulk: rapid charge phase from 0 to 80%Absorption: equalization phase charging the battery from 80 to 100%Float: maintenance phase keeping the battery at full charge without damaging it.

Yes, it is fully protected against short circuits and overloads. In the event of such a problem, the alarm contact opens to signal the malfunction and protect the installation.
