The rugged 390V BoostCap ultracapacitor module provides scalable, energy-storage and power-delivery solutions for heavy hybrid and electric vehicles and heavy-duty industrial applications requiring up to 1170V. Designed to perform reliably through one million or more deep-discharge cycles, or about 15 years of operational life for most vehicles or industrial systems, the unit integrates voltage-management circuitry and monitoring capabilities and a highly efficient, fan-driven, forced air cooling that ensures good thermal performance at high continuous currents. The self-cooled HTM BMOD0018-P390 is encased in a rugged, splash- and dust-proof, IP-65compliant, aluminium chassis. Each module is rated at 18Fd, and up to three modules may be linked in series.
