Reliable and fast energy storage

Supercapacitors for DC applications

Eaton supercapacitors is a range of high-reliability, high-power, ultra-high-capacitance energy storage devices utilizing electrochemical double-layer capacitor (EDLC) construction combined with proprietary materials and processes. This combination of advanced technologies allows Eaton to offer a wide variety of capacitor solutions tailored to applications for back-up power, pulse power, and hybrid power systems. They can be applied as the sole energy storage or in combination with batteries to optimize cost, lifetime, and run time. System requirements can range from a few micro-amps to megawatts.

Eaton XLR modules

The Eaton XLR modules are self-contained energy storage devices comprised of 18 individual supercapacitor cells. The module includes bus bar connections, integrated cell voltage management circuitry, an overvoltage alarm, and a thermistor for measuring the internal temperature of the cells. Due to the very low equivalent series resistance (ESR) of the supercapacitors, minimal heat is generated during operation. Units may be connected in series to obtain higher operating voltage in parallel to provide higher current, high power, or longer run time, or a combination of series/parallel arrangements, as needed.
