Mascot Industrial charger 9541-24 24V 25A

The Mascot 9541-24 is an extremely powerful high-frequency charger, designed for professional applications that require reliable power supply for large 24V lead battery systems. With a maximum charging current of 25 amps and a robust metal housing, this device provides the necessary reserves for use in workshops, the marine sector or industrial facilities. It ensures fast recharging and precise battery maintenance through intelligent charging technology.

Highlights at a glance

• High charging power: Delivers up to 25 amps charging current, which allows fast charging of high capacity battery banks (e.g. in cleaning machines or boats).
• Intelligent 3-stage charging: The processor-controlled charging procedure (IUU) with timer function ensures optimum saturation of the battery and prevents harmful overcharging.
• Temperature compensation: The connection for an external temperature sensor enables the automatic adjustment of the charging voltage to the ambient temperature, which significantly increases the battery's lifespan.
• Industrial design: A robust metal chassis and an active fan cooling system make the device resistant for permanent use in demanding environments.
• Flexible output: Equipped with sturdy screw terminals for secure connection of thick charging cables; often also available as a version with two outputs (2x 12.5A).
• Comprehensive protection: The electronics are protected against short circuit, reverse polarity and overheating to ensure maximum operational safety.

Powerful technology for large 24V batteries

The Mascot 9541-24 operates with an efficient 3-stage characteristic. In the first phase (Boost), the battery is charged with a maximum current of 25A until the end-of-charge voltage (typically 29.4V) is reached. This is followed by the timer phase, during which the voltage remains constant while the current drops, ensuring that the chemical processes in the battery are fully completed. Finally, the device lowers the voltage to a safe level (float at 27.4V) to keep the battery permanently fully charged without "gassing" or water loss.

Ideal for heavy duty, marine and automotive

This charger is not a classic plug-in power supply, but a real powerhouse. It is perfectly suited for stationary use in charging rooms, for wall mounting in service vehicles or as an onboard charger on ships. It reliably supplies forklift batteries, aerial work platforms, or large emergency battery banks.

FAQs about the Mascot 9541-24 charger

Is the charger suitable for outdoor use?

No, the device has protection class IP20. This means it is protected against contact and larger foreign objects, but not against water or moisture. It should be installed in dry indoor areas, control cabinets, or protected enclosures.

For which battery capacity is it recommended?

With 25 amps charging current, the device is ideal for battery capacities between approx. 100 Ah and 500 Ah. For smaller batteries (under 80 Ah), the charging current could be too high, which would strain the battery.

Why does the device have a fan?

At a charging power of 24V and 25A, heat is generated. The integrated fan provides active cooling for the power electronics to ensure stable performance even under continuous load. The fan is often temperature-controlled.

What does the temperature sensor do?

The (usually optional or included) sensor is attached to the battery. It measures the temperature of the battery. If the battery is hot, the charger lowers the voltage to avoid overheating. If it is very cold, the voltage increases slightly to ensure the battery still gets fully charged. This is very important for the longevity of large lead batteries.
