Product Description:

The Beckhoff C9900-U320 is a DIN rail-mountable uninterruptible power supply (UPS) designed to provide reliable backup power to Beckhoff Industrial PCs (IPCs) during a primary power failure. As part of the C9 PC Accessory Series, this robust unit ensures continuous operation and prevents data loss in critical applications. This UPS utilizes a NiCad battery with a capacity of 2.5 Ah, delivering an output voltage of 24 VDC. It offers a charging current ranging from 200 to 800 mA, allowing flexible charging options. The C9900-U320 is specifically designed to operate within a wide temperature range of 0 to 55°C, making it suitable for demanding industrial environments.

One key feature of the C9900-U320 is its reverse battery protection. A fuse on the C2000BAT board safeguards the unit from damage caused by accidental reverse battery connection damage. This ensures the longevity and reliability of the UPS, minimizing downtime and potential repair costs. The C9900-U320 is controlled by C1230S or CP9030 boards, allowing seamless integration with existing Beckhoff control systems. Charging time for the battery is up to 4 hours, providing ample backup time to save critical data and perform a controlled shutdown of the IPC in case of a power outage.

For optimal performance, Beckhoff recommends using cables with a maximum length of 4 meters for a 1.5 mm² cross-section and 8 meters for a 2.5 mm² cross-section. The unit connects to the IPC via ST501 and ST703 ribbon cables, ensuring secure and reliable data transfer. Its compatibility with C1230S and CP9030 control boards and ease of installation make it a valuable addition to any Beckhoff IPC system, ensuring continuous operation and preventing costly data loss.
