XLR Module

Eaton XLR Supercapacitor Module

48 V Supercapacitor Module

The Eaton XLR Provides energy storage for high power, frequent charge/discharge systems in hybrid or electric vehicles, public transportation, material handling, heavy equipment, marine systems. The XLR module can reduce battery size and weight or replace batteries altogether depending upon the load profile. This results in fuel savings, noise reduction and/or a more stable electrical system.

The XLR supercapacitor module is a self-contained energy storage device comprised of 18 individual XL60 supercapacitor cells. The 48 V, 166 F, 5 mohm module is easily mounted and includes integrated cell voltage management circuitry and an overvoltage alarm.
