Mascot Lead-acid battery charger 9740-48 48V 2.5A
Description
Product information
The Mascot 9740-48 is a high-quality desktop charger specially designed for 48V lead-acid battery systems. With a charging current of 2.5 amps and the proven 3-stage charging characteristic, it ensures efficient and gentle charging. The combination of medical certification (EN 60601-1) and protection class IP21 makes this device the ideal choice for professional use in medical technology, e-mobility and industrial applications that are operated on stable 230V networks.
Highlights at a glance
- Intelligent 3-stage charging: The fully automatic charging cycle (I-U-U) with timer control ensures optimum saturation of the battery and maximises its service life.
- Medical approval: Meets the strict safety requirements of the EN 60601-1 standard (3rd edition) for safe use in the direct patient environment.
- Reliable performance: With a charging current of 2.5 amps, the device provides a stable power supply for 48V systems.
- Dedicated input: Designed for an input voltage range of 198 - 264 VAC, specially optimised for European 230V networks.
- Solid protection (IP21): The housing is protected against solid foreign objects (>12mm) and vertically falling dripping water.
- Clear status display: A 3-colour LED display (orange/yellow/green) provides intuitive information about the current charging progress.
Precise charging technology for 48V systems
The Mascot 9740 utilises a highly developed 3-stage charging process. In the first phase (cycle), the device charges with a constant current of 2.5A until the final charging voltage of approx. 58.8V is reached. This is followed by a timer-controlled phase in which the voltage is kept constant to ensure that the cells are fully saturated. Finally, the charger switches to trickle charging (float at approx. 54.8V), whereby the battery remains permanently ready for use without being overcharged.
Ideal for medical and demanding applications
This model is ideal for powering 48V applications, such as those found in e-mobility (scooters, golf caddies), stair lifts or medical transport equipment. The robust design and compliance with medical standards ensure safe operation even in sensitive environments.

FAQs about the Mascot 9740-48 charger
What does the input voltage range 198-264V mean?
This range indicates that the charger is specially designed for 230V networks (as is usual in Europe). It is not suitable for worldwide use on 110V networks (e.g. USA), which often enables a more efficient design of the components for the target market.
Can I leave the charger permanently connected to the battery?
Yes, the Mascot 9740 is designed for continuous operation. Once the main charge is complete, it automatically switches to float charge mode, which compensates for natural self-discharge and keeps the battery gently at 100%.
For which battery capacities is it suitable?
With a charging current of 2.5 amps, this device is ideal for 48V batteries with a capacity of between approx. 10 Ah and 60 Ah. Charging is possible for larger capacities, but takes longer.
What do the LED colours mean?
- Orange: Main charge with maximum current (battery is charged).
- Yellow: Timer phase with constant voltage (saturation phase, battery almost full).
- Green: Trickle charge (charging process completed, battery is full).
