PowerStor Supercapacitors
The PowerStor brand of supercapacitors offers ultra-low resistance supercapacitors, unique high-energy storage devices.
Supercapacitors Extend Battery Life
The PowerStor A series supercapacitors are available in values from 0.47F to 4.7F, 2.5V and offer equivalent series resistance as low as 25mΩ. In remote battery powered applications that have pulse current loads this low ESR can be utilized to prolong battery life.
Low cost battery solutions tend to have high ESR and as a result large amounts of stored energy can’t be used when supplying pulse currents. By combining a supercapacitor in parallel with the battery the overall ESR is lowered and battery life, typically, increased by 300%. For remote applications such as utility meters, weather & river level monitoring and hotel door locks this can dramatically reduce replacement costs.
Offering Environmentally Friendly Alternative to Ni-CD Batteries
The PowerStor B series is available in values from 0.22F to 50F, 2.5V and is fully compliant with the EC RoHS directive. For equipment that is only required for short term use, up to several minutes, and has a local charger the B series offers a realistic alternative to Ni-CD batteries.
ow equivalent series resistance allows the B series parts to be rapidly charged and discharged without damage and low leakage current means they can hold their charge for weeks. Unlike batteries PowerStor supercapacitors have a very long cycle life, over 500,000 cycles, so they won’t need replacing and at end of life there are no recycling or disposal issues.
Supercapacitors Provide Last Gasp Power
The PowerStor P series is available in values from 0.1F to 1.0F, 5V and is ideal for hold-up and bridging power applications. For telecom products such ADSL routers a P series supercapacitor can be used to provide power for a ‘leaving network’ signal after a mains supply failure.
Unlike batteries the P series supercapacitors have a long cycle life, over 500,000 cycles, so they won’t need replacing. In addition to this they have ESR as low as 0.2 Ohms and small package sizes from 0.75 cm3 to 4.7 cm3. All this makes the P series an ideal choice for supporting continued operation during battery swap-out or for controlled shut down after a mains failure.
Providing Power Management Solutions
In addition to a broad range of standard products PowerStor also offer custom solutions for applications such as automated meter reading, PCMCIA cards, handheld electronics, data storage systems and toys.
These products include high integrity capacitor packs that incorporate active voltage balancing and optimized cylindrical components that meet specific customer requirements.
