Beckhoff Automation debuts one-cable uninterruptible power supply

Beckhoff Automation has released the U81xx uninterruptible power supply (UPS) series, designed for universal use in the field.

The series features One Cable Technology (OCT) for uninterruptible power supply (UPS-OCT) and 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 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.

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 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.
