48V Ultracapacitor Module

Our industry-leading 48V module now includes the benefits of our new DuraBlue™ Advanced Shock and Vibration Cell Technology.

The new module has been tested to meet and exceed the industry’s highest shock (IEC 60068-2-27 and 2-29) and vibration (ISO 16750-3, Tables 12 and 14) ratings for ultracapacitor / supercapacitor modules, exceeding the most demanding testing requirements for transportation applications such as in hybrid buses, particularly in China. The enhanced module has been validated through several months of sampling with selected customers and is immediately available.

Maxwell’s DuraBlue™ Advanced Shock and Vibration Technology is the company’s latest advance in ultracapacitor / supercapacitor reliability and performance. It combines Maxwell’s unique dry electrode formation and manufacturing process with a patent-pending cell structure design, resulting in a significant increase in vibration immunity of as much as 300 percent and in shock immunity of as much as 400 percent versus most comparable competitive offerings. The new module will offer advanced capacitor management system options (CMS) for improved reliability as well as safety enhancements which include a redundant over-voltage alarm, while maintaining existing product life characteristics.
