Product details
In the critical applications of telecom infrastructure and the power industry, a reliable backup power source is the cornerstone for the stable operation of systems. As a member of the B.B. Battery MSU series, the MSU-400 is specifically designed to meet such high requirements. This series of batteries is manufactured as a 2-volt monoblock, with a capacity range from 200 to 3000 ampere-hours, specifically developed for power supply networks, the power industry, and telecom applications, renowned for its long float life and high capacity. The MSU-400 has a nominal capacity of 400 ampere-hours, providing stable and long-lasting power support under 10-hour rate discharge conditions. Its sealed structure ensures no electrolyte leakage or overflow, making it safe and reliable.
The shell of MSU series batteries is made of sturdy opaque impact-resistant ABS plastic. The battery cover is firmly connected to the shell, and the terminal area is tightly sealed. The battery cover is designed with six filling holes, through which electrolyte is filled during the production process, followed by the installation of a pressure relief valve made of non-combustible materials. This design not only ensures a high level of fire and explosion safety but also reflects comprehensive consideration of the usage environment. The battery can be installed flexibly, accommodating both horizontal and vertical positions, which facilitates installation in computer rooms and equipment in different spatial layouts. Its terminal design varies by type; the MSU-400 offers standard terminal types to meet conventional connection requirements.
At the core technology level, the MSU-400 adopts gel technology electrolyte. Through a unique electrolyte fixing system, it maximizes the battery's service life. The high-tech alloy used to manufacture the grid ensures extremely high corrosion resistance, while the special active material formulation provides good charge acceptance. These innovations together ensure the battery's performance stability during long-term floating use. Under normal working conditions, the expected service life of MSU series batteries can reach 15 to 18 years, meeting the definition standard of long-life batteries by Eurobat.
This battery is compactly designed, with a length and width of 174 mm each, a height of 330 mm, total height 360 mm, and a weight of approximately 24.5 kg, making it easy to deploy and handle in data centers or equipment cabinets with limited space. Its extensive application scenarios make it a key power solution for multiple industries. It is not only an ideal choice for telecommunication facilities, central computer rooms, and uninterruptible power supply systems, but also can be seamlessly integrated into renewable energy systems such as solar and wind energy storage.In addition, MSU-400 can provide reliable backup power in data processing centers, oil and gas extraction, fire and safety alarm systems, emergency lighting, video surveillance, access control, medical equipment, rural estates, hotels and stores, and electric vehicle charging infrastructure. Whether addressing grid fluctuations or serving as an effective supplement to the main power supply system, it ensures the continuous operation of critical business and is a wise choice for users seeking high efficiency and long-term reliability.
