90V Ultracapacitor Module

Maxwell’s 90-volt module has a 10 farad capacitance and low equivalent series resistance (ESR) for high power delivery.

Our customers capitalize on this solution’s long lifetime and durability. The 90-volt module contributes to minimal maintenance requirements after system deployment, adding significant value to system performance over time.

The solution features an integrated Ultracapacitor management unit (UMU) for streamlined integration and monitoring.

The UMU provides:

  • Individual cell balancing
  • Voltage and temperature monitoring
  • Reverse polarity detection
  • Digitalized signals that are communicable to the user’s interface

The module is designed for indoor cabinet environments with an operating temperature range of –40°C to 65°C,* providing much more flexible performance compared to battery energy storage options.


  • Wind turbine pitch control system
  • Industrial UPS and DVR

We offer Maxwell’s 75-volt ultracapcitor module and 240-volt ultracapacitor module in addition to the 90-volt ultracapacitor module version for these applications.
