Maintenance-free industrial UPS has no batteries

03 November, 2014

Panduit has launched a maintenance-free uninterruptible power supply (UPS) that backs up industrial managed Ethernet switches using ultra-capacitors instead of batteries, thus eliminating the main cause of conventional UPS failures. The company says that its Industrial Network UPS will lower the risk of downtime due to battery failures by 39%, as well as doubling the return-on-investment and cutting the cost of ownership by 50-70% compared than conventional UPSs.

The 35W (24–28V DC, 1.6A) rail-mounting UPS is said to take up about half of the space needed for a battery-powered UPS. It has service life of more than ten years, compared to 1–5 years for a battery-powered system, and a wider operating temperature range: –40 to +60°C, rather than 0–40°C.

The UPS can be managed remotely via standard Web browsers, or Rockwell Automation’s FactoryTalk View faceplates. It is EtherNet/IP conformance-tested and UL508 listed.

“With many manufacturers and processors dealing with the issue of a shortage of skilled labour, maintaining batteries in UPS systems can often fall through the cracks, and often goes unnoticed until the UPS is needed, and by then it is too late,” comments Craig Resnick, vice-president of ARC Advisory Group. “UPS systems that utilise ultra-capacitor technology, such as the Panduit UPS, eliminate this issue for the most frequent types of power loss, which are momentary or short-term, preventing the havoc on the factory or plant floor caused by temporarily losing power to HMIs, network switches, and so on.”
