Eaton Electronics PTV Supercapacitors are high-reliability, high-power, ultra-high capacitance energy storage devices that utilize electric double-layer capacitor (EDLC) construction combined with proprietary materials and processes. The capacitors can be applied as the sole energy storage or in combination with batteries to optimize cost, lifetime, and run time. The series features low ESR for high power density with environmentally friendly materials for a green power solution. Eaton Electronics supercapacitors are maintenance-free, with design lifetimes of up to 20 years and operating temperatures between -40°C and +85°C. The technology featured in Eaton Electronics PTV Supercapacitors makes this series ideal for applications for backup power, pulse power, and hybrid power systems.
