The most important benefits of
using SkelMod 171V Module

High power
Low ESR & high power in a compact package

SkelMod 171V is changing the game when it comes to ultracapacitor modules. Offering both low Equivalent Series Resistance (ESR) and high power in a compact package, SkelMod 171V provides the perfect balance between energy storage and delivery. It's ideal for applications such as wind turbine pitch control and industrial processes that require maximum performance, allowing users to unlock their full potential in ways they never thought possible before.

Low heat generation
Lowest heat generation under high power profiles

SkelMod 171V 5.8F ultracapacitor modules provide a powerful solution for applications resulting in high power profiles, such as wind turbine pitch control and industrial processes. Generating low heat under these challenging conditions makes SkelMod 171V an ideal choice for reliable operation over extended periods of time. SkelMod 171V's innovative design ensures maximum performance with minimal strain on environment and budget, making SkelMod 171V 5.8F the perfect solution for any energy storage needs.

-40 degrees
-40°C to +65°C operating temperature range

SkelMod offers a robust and reliable high voltage pitch control solution with their 171V module. Operable in temperatures ranging -40°C to +65°C, SkelMod's 171V module is an improved alternative over the 160V modules currently on the market, as multiple SkelMod 171V modules can be used in series to increase product lifetime. This small form factor product drastically improves reliability, making SkelMod 171V a great choice for any project requiring maximum performance despite extreme weather conditions.


"The high quality of both our supercapacitor modules and our service is why our customers trust us."
