Vzdrževalnik baterij Sterling Power 24/12V 1A

The Sterling Power BM24121 battery maintainer is a device designed to maintain the charge of 12V auxiliary batteries from a 24V DC main battery system. It ensures that your secondary equipment always has power without risking discharge of the main battery.

Its primary function is to compensate for the self-discharge of 12V auxiliary batteries and maintain their optimal charge level over the long term. It is specifically a battery maintainer, not a fast charger.

The BM24121 maintenance unit uses field-effect transistors (FET) for power management. This technology is more efficient and durable than relay-based solutions.

FET technology offers several advantages:

Minimal electrical consumption, under 1 mA.No physical contacts, eliminating mechanical wear and noise.An extended device lifespan.

The Sterling Power BM24121 battery maintainer’s power consumption is minimal, under 1 mA. This makes it particularly suitable for installations with limited power sources, such as solar or wind.

Yes, by constantly maintaining the optimal charge level of the 12V auxiliary batteries, the BM24121 maintainer prevents deep discharge. Deep discharge is a major factor in battery degradation, and this process helps extend their lifespan.

Yes, the Sterling Power BM24121 battery maintainer is ideally designed for marine applications and leisure vehicles such as motorhomes, where it ensures a constant supply of power for secondary equipment.

Yes, thanks to the use of FET technology and the absence of physical contacts, the BM24121 charger is silent in operation, as there is no mechanical wear or noise associated with relays.

Thanks to its advanced FET technology that eliminates mechanical wear and reduces power consumption, the BM24121 battery maintainer is designed to provide extended service life.

The Sterling Power BM24121 battery maintainer provides an output current of 1A. It is designed for battery maintenance, not for fast charging.

The BM24121 maintainer is designed to maintain a 12V auxiliary battery. If you have multiple 12V auxiliary batteries, they should be connected in parallel to be maintained by this device, provided the total capacity remains suitable for a 1A maintenance current.

The Sterling Power BM24121 battery maintainer is designed to work with a 24V DC main battery system.

This maintainer is designed to maintain 12V auxiliary batteries. It is generally compatible with common lead-acid battery types such as AGM, Gel, and flooded batteries, used in marine and recreational vehicle applications.

No, the Sterling Power BM24121 battery maintainer is specifically designed for a 24V DC main system. It will not operate correctly with a 12V main system.

Yes, this maintainer can be used to maintain a 12V starter battery, provided it is treated as an auxiliary battery in a 24V DC main system. Its role is to compensate for self-discharge and extend battery life.

The device activates when the 24V main battery reaches a voltage of approximately 26.6V. This ensures that only a sufficiently charged main battery powers the auxiliary circuit.

The maintainer is electrically connected between the 24V main system and the 12V auxiliary battery. It is essential to follow the installation manual instructions to ensure correct polarity connections and optimal safety.

During installation, ensure the device is mounted in a dry, well-ventilated location, protected from moisture and extreme temperatures. It is critical to observe polarity when connecting to batteries to prevent damage to the device or electrical system.

Yes, as with any high-power electronic equipment, it is recommended to install the BM24121 battery maintainer in a location with good airflow. This ensures heat dissipation, optimizes performance, and extends the device’s lifespan, even though its power consumption is very low.
