The Beckhoff C9900-U330 is a high-performance battery pack with integrated UPS functionality, engineered to provide reliable backup power for Beckhoff Industrial PCs and automation systems operating on a 24 V DC power supply. With a nominal capacity of 3.4 Ah, the C9900-U330 ensures continued operation during power interruptions, protecting critical data and maintaining system availability in demanding industrial environments.

At the core of the C9900-U330 is a 24 V nominal voltage supply, achieved by an internal configuration of two 12 V batteries connected in series. This design provides dependable backup power for connected PCs and automation hardware, bridging short-term power losses and allowing time for controlled system shutdowns. By safeguarding against unexpected outages, the C9900-U330 minimises downtime and reduces the risk of data loss or system damage.

Housed in a rugged metal enclosure, the C9900-U330 is built for long-term industrial use. Its design allows for straightforward installation on TS35x15 2.3 norm rails, making it easy to integrate into standard control cabinets. The compact dimensions of 157 mm (W) × 70 mm (H) × 175 mm (D) ensure that the unit fits neatly into automation panels without occupying excessive space, an important advantage in cabinet-constrained applications.

A key safety feature of the C9900-U330 is its 9 A fuse protection, implemented via a PTC (Positive Temperature Coefficient) element. This protects both the battery pack and connected equipment from overloads and electrical faults, enhancing overall system safety and reliability. The integrated protection also extends the service life of the battery pack by reducing the risk of excessive current draw.

The nominal capacity of 3.4 Ah (measured at a 20-hour discharge rate) provides sufficient backup energy for typical automation tasks. This allows Industrial PCs and controllers to maintain functionality long enough to complete essential operations or initiate an orderly shutdown sequence, preventing data corruption and ensuring operational integrity.

In practical applications, the C9900-U330 is widely used in manufacturing plants, process control systems, and building automation setups, where maintaining uninterrupted control is essential. It serves as a crucial safeguard for automation infrastructures, helping to ensure continuity of operations even in the face of unstable power conditions.

In summary, the Beckhoff C9900-U330 is a robust and reliable UPS battery pack designed for Industrial PCs with 24 V DC supplies. Offering a 3.4 Ah capacity, rugged DIN rail-mountable housing, built-in fuse protection, and compact form factor, it delivers dependable backup power for automation systems. For organisations requiring system protection and continuity in the event of power interruptions, the C9900-U330 represents a practical and effective solution.
