Description
Eaton PowerStor supercapacitors are unique, ultra-high
capacitance devices utilizing electrochemical double layer
capacitor (EDLC) construction combined with new, high
performance materials. This combination of advanced
technologies allows Eaton to offer a wide variety of capacitor
solutions tailored to specific applications that range from pulse
power to back up power to load leveling to energy storage.
The XM series provides the lowest ESR in its class in a cost
effective size. This translates to a high power, high efficiency
supercapacitor. As with all of Eaton PowerStor
supercapacitors , the XM series is a green energy storage
solution with long calendar life and high charge/discharge life
over a broad temperature range.
