C9900-U332 by Beckhoff

The C9900-U332, part of Beckhoff's C9 PC Accessories, is engineered as a specialized battery pack designed for PCs with a 24 V power supply and integrated UPS capabilities. Manufactured by Beckhoff, this component is tailored for use with PCs with Intel Atom processors and features an internal structure comprising two 12 V batteries in series connection. Its primary function is to provide an uninterruptible power supply, ensuring that the PC continues to operate or shuts down gracefully when mains power fails. Key features include the maintenance-free operation and a nominal capacity of 1.2 Ah (20 h discharge), both of which underscore its reliability in industrial environments.

The technical specifications of the C9900-U332 display a compact design with dimensions of 68.7 mm x 106.6 mm x 143.8 mm and a robust metal housing for mounting on norm rail TS35x15 2.3. With a nominal voltage of 24 V and designed to operate within a temperature range of 0...+50°C, the battery pack is optimized for challenging industrial conditions. Its vertical mounting orientation, combined with its intended use on a DIN rail outside the PC, enhances both accessibility and heat management. The integrated UPS function not only safeguards data integrity during power outages but also supports controlled shutdown procedures.

In addition to its core specifications, the C9900-U332 offers enhanced durability and ease of installation through its maintenance-free design and vertical layout. Weighing only 2.1 kg, it balances compactness with effective power storage, making it ideal for space-constrained industrial control cabinets. The construction using a metal housing provides robust protection and supports efficient thermal dissipation. Overall, this battery pack contributes significantly to ensuring continuous uptime and operational stability in industrial applications, making it a valuable asset in environments where reliability and uninterrupted performance are paramount.
