New UPS Series With One Cable Technology Minimizes Installation Work

PB 27 Beckhoff CU81 400

Oct 15, 2019

The new CU81xx uninterruptible power supply (UPS) series is 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. In combination with the Beckhoff Industrial PCs (IPCs), particularly efficient cabling is possible with just one cable for 24 V supply and communication through UPS-OCT.

The uninterruptible power supply units in the CU81xx series have been designed for rear panel and DIN rail mounting. At present, one capacitive and two battery-assisted versions are available:

  • CU8110-0120: capacitive UPS (0.9 Wh) with a maximum power output of 120 W
  • CU8130-0120: battery-backed UPS (15 Wh) with a maximum power output of 120 W
  • 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 for easy replacement. The UPS neither needs to be dismantled nor dismounted from the DIN rail for this purpose. It is only necessary to release two screws in the cover to replace the battery module.

One-cable solution offers clear benefits

A special 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 IPCs with an appropriate interface and Windows 7 or 10 operating system can easily connect via USB 2.0. In the simplest case, such as when using a traditional PLC, digital I/Os are also available so that, for example, the controller can read a power fail signal and respond accordingly.

The UPS connection supports even more convenient implementation with the UPS-OCT one-cable solution, which is currently supported by the ultra-compact 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 V DC cable, which greatly simplifies installation. All Beckhoff Industrial and Embedded PCs will support UPS-OCT in the future.
