XLM Supercapacitors


XLM 62V Supercapacitor Module.

The Eaton XLM provides energy storage for bridge power uninterruptible power supplies (UPS) and improves power quality for voltage spikes and brown outs. The XLM is a safer alternative to batteries for UPS back up power applications. Supercapacitor modules are lead-free and RoHS compliant and require no battery management system (BMS) due to Eaton’s patented active cell balancing technology. With up to a 20 year lifespan, the XLM module can increase the life of a back-up system and eliminate the need for replacement parts and batteries.


  • Long lifetime (Operating lifespan of up to 20 years)
  • Maintenance free (No monitoring or user controls required)
  • No chemical reaction (Fast response to switched outages)
  • No C rate limitations (High availability due to fast recharging)
  • Low ESR for high power density (Peak power is 15kW/kg per cell and 8kW/kg per module)
  • Rack mounted (Easily rack mountable due to 4U height by 6.9" wide size)
  • Lightweight (Reduces rack requirements and floor reinforcement)


  • Datacenter UPS
  • Bridge power
  • Hospital UPS
  • Hybrid power system with fuel cells
