Designed for universal use in the field, with flexible and cost-saving connection options, including one cable technology (OCT) for uninterruptible power supply (UPS-OCT), the CU81xx series is suitable for a broad range of applications. This includes connection to the entire range of Beckhoff components — in particular the Industrial, Panel and Embedded PCs — as well as third-party products. The series was designed for rear-panel and DIN rail mounting. At present, one capacitive and two battery-assisted versions are available: the CU8110-0120 capacitive UPS (0.9 Wh) with a maximum power output of 120 W, the CU8130-0120 battery-backed UPS (15 Wh) with a maximum power output of 120 W, and the CU8130-0240 battery-backed UPS (30 Wh) with a maximum power output of 240 W. In the battery-backed versions, the NiMH battery cells are accessible from the front by removing just two screws for easy replacement.
