UPS series with One Cable Technology

The UPS units from Beckhoff’s CU81xx series have been designed for rear panel and DIN rail mounting. 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-assisted versions, the NiMH battery cells are accessible from the front should they need to be replaced. It is only necessary to release two screws in the cover to replace the battery module.

A feature of the UPS series is its flexible communication capability, which allows the retrieval of status values for diagnostic purposes or the configuration of the UPS. All industrial PCs with an appropriate interface and Windows 7 or 10 operating system can thus be connected in the conventional way via USB 2.0. In the simplest case, eg, when using a classic PLC, digital I/Os are also available so that the controller can read a power fail signal and respond accordingly.

The UPS connection can also be implemented with the Beckhoff One Cable Technology (UPS-OCT) solution, which is currently supported by Beckhoff’s C6030 IPC, the CX52xx embedded PC series and the CX2100-0024 embedded PC power supply unit. This solution combines the IPC power supply with the UPS communication in a single 24 VDC cable.
