Power management company Eaton has developed the XLM Supercapacitor Energy Storage Module designed to provide fast discharge for bridge events in uninterruptible power supplies (UPS) for mission critical applications. The modules offer a green alternative to lead-acid-batteries and are designed to be maintenance free for grid storage and backup power applications. The company claims the XLM module can significantly lower the total cost of UPS ownership in cloud computing, data center, hospital UPS, semiconductor industry, and other markets.

Eaton officials said the XLM modules enable graceful shutdown of systems, the ability to ride through power transients such as sags, spikes, and dropouts in order to smoothly transition to permanent backup solutions such as fuel cells or diesel generators. These modules contain 69-watt hours and the ability to discharge 7,800 amps.

The XLM modules are self-contained devices housing 23 individual Eaton XL60 supercapacitor cells. Modules are lead-free and compliant with the Reduction of Hazardous Substance Directive (RoHS) for green applications.
