The MC Series
Maxwell’s Ultracapacitors provide extended power availability, allowing critical information and functions to remain available during dips, sags, and outages in the main power source. In addition, it can relieve batteries of burst power functions, thereby reducing costs and maximizing space and energy efficiency. The ultracapacitor features a cylindrical design and an electrostatic storage capability that can cycle hundreds of thousands of charges and discharges without performance degradation.
Designed as a cylindrical package with termination at either end, Maxwell's MC Series ultracapacitors are a technological breakthrough that provides 2.7 volt operating voltage while still maintaining Maxwell’s Ultracapacitors high performance and high reliability. These cells are ideal for automotive subsystems, medical devices, UPS/backup power, wind turbine pitch control, and many other applications requiring a pulse of energy that cannot be efficiently provided by a battery or power supply alone.
The MC Series works in tandem with batteries for applications that require both a constant low power discharge for continual function and a pulse power for peak loads. In these applications, the device relieves batteries of peak power functions resulting in an extension of battery life and a reduction of overall battery size and cost.
The MC Series is also an ideal source of back-up power and pulse. It can provide extended power availability, allowing critical information and functions to remain available during dips, sags, and outages in a power supply or battery change. And, like all Maxwell ultracapacitors, the MC Series is capable of accepting changes at the identical rate of discharge.
