Maxwell Ultracapacitor Uninterruptible Power Supply (UPS) Solutions

Computers, telecommunications, internet data centers, hospitals, industrial buildings, and broadcast systems have become so entrenched in our daily lives that if a network is interrupted for even a short time, the interruption can, at best, inconvenience users and, at worst, cripple a business for days, weeks or longer. Until recently, ultrapacacitors have not been considered for large-scale uninterruptible power supplies (UPS) while energy storage was dominated by lead acid batteries. Since today’s complex computing and networking systems are so crucial to everyday life, businesses need to select UPS systems implementing ultracapacitors that can provide short-term bridge power to allow a network to be transferred to a secondary power source or gracefully shut down in a controlled, orderly fashion. Ultracapacitors are more reliable than batteries, maintenance free and have a much longer life.

When it comes to selecting a UPS system, reliability should be the number one factor in your choice. Maxwell ultracapacitors have demonstrated their durability and reliability in delivering power bursts safely for more than a million cycles, virtually eliminating site maintenance visits to change out batteries. Ultracapacitors provide high reliability back up power to buffer poor power transients or relieve fuel cells from having to come on at all – reducing overall system wear and tear as well as maintenance and costs. Implementing an ultracapacitor solution provides a long-life (8 – 14 years), reliable, green and extremely powerful energy storage that easily outlasts the product into which they are designed. Indeed, ultracapacitors have become a viable component for production-intent designs in the power electronics world. Many companies, recognizing the technical advantages and high availability of ultracapacitors, are producing ultracapacitor systems.

Maxwell Ultracapacitor UPS Applications:

Maxwell ultracapacitors are used in more than 35,000 UPS installations. Ultracapacitors offer the most reliable, longest life worry-free energy storage for UPS applications. They have been in operation in the following applications:

Ultracapacitors for Datacenter UPS

• The number one job of UPS is to manage a system’s electrical faults, not electrical outages. System electrical faults include breaker trips, voltage sages, power surges, frequency variations, waveform distortions, spikes and noise. Maxwell ultracapacitors easily integrate into UPS cabinets to satisfy the energy storage and power delivery demands of large systems. The ultracapacitor meets every requirement for a UPS system when it comes to high durability and reliability, a long life cycle, and the maintenance-free capability makes it the ideal power backup solution.

• Maxwell ultracapacitors are ideal for mission-critical systems in telecommunications that requires continuous operation, minimum to no maintenance, high reliability and available bridge power backup for seconds to minutes while the power is gracefully moved from the failed system to a backup source.

• The long predictable life of ultracapacitors makes them ideal for hospitals and medical equipment. Ultracapacitor UPS systems provide smooth power to shutdown safely or ride through for a permanent primary power backup (typically a fuel cell or diesel generator).
