Product details
In telecommunications, power networks, and renewable energy systems, stable and reliable backup power is crucial for ensuring continuous operation. MSU series VRLA batteries, such as the MSU-400 model, are specifically designed for such high-demand scenarios. This series adopts a 2V integrated structure with capacities ranging from 200 to 3000 Ah, where the MSU-400 has a nominal capacity of 400 Ah at a 10-hour rate, providing long-lasting power support for various facilities.
The shell of MSU series batteries is made of sturdy impact-resistant ABS plastic, and this opaque material ensures the durability of the battery.The battery cover is firmly integrated with the shell, and the terminal area is sealed, effectively preventing electrolyte leakage or overflow and meeting the design requirements of the sealed structure. Depending on the specific model, the terminal design may vary, providing users with flexible connection options. The six holes on the battery cover are used for electrolyte filling during the production process, and a pressure relief valve made of non-combustible materials is subsequently installed. This design not only ensures the fixation of the electrolyte but also greatly enhances the battery's safety against fire and explosion, making its application in environments such as data centers, energy storage systems, or central computer rooms more reassuring.
Inside the battery, both the positive and negative plates are coated with special pasty active materials.This unique formula, combined with grids made of high-tech alloys, endows the battery with excellent corrosion resistance and good charge acceptance. The unique electrolyte fixing system, specifically using gel electrolyte technology, further extends the expected service life of the battery under normal operating conditions to 15 to 18 years, meeting the long-life definition under the Eurobat standard. This innovative technology not only maximizes the extension of the service life but also ensures long-term performance stability.
In terms of installation, the MSU-400 battery offers great flexibility and can be safely installed in horizontal or vertical positions.Its external dimensions are compact, with a length and width of 174 mm each, a height of 330 mm, and a total height of 360 mm, making it easy to install in cabinets or battery racks with limited space. The weight is approximately 24.5 kg, and corresponding load-bearing capacity should be considered during deployment.
The MSU series batteries have extremely wide application scenarios. It is not only an ideal power source for telecommunication facilities, power supply networks, and the power industry, but also perfectly suitable for renewable energy systems such as solar and wind energy storage. Additionally, it serves as a reliable backup power for uninterruptible power supplies (UPS), data processing centers, oil and gas extraction, fire alarm systems, security systems, emergency lighting, video surveillance, access control, and medical equipment.It can also be seen in power supply solutions for rural estates, hotels, stores, and even electric vehicle-related facilities. The anti-corrosion properties of its high-performance alloy, the maintenance-free convenience of its sealed structure, and the long service life brought by the gel electrolyte technology together constitute its core advantages in key fields such as UPS, energy storage systems, and central computer rooms.
