The Eaton XTM-18 Supercapacitor Module: Providing High Density Power for Automation

November 18, 2019 by Luke James

The XTM-18 Supercapacitor Module is a high-reliability energy storage solution that provides high-density power for a variety of automation machines.

Eaton’s XTM-18 Supercapacitor Module is a highly reliable and cost-effective energy storage solution. It provides high-density power for a variety of potential applications that involve automation. 


Up To 20 Years’ Worth of Long-Life Energy Storage

The XTM-18 provides up to 20 years’ worth of long-life energy storage. Utilizing an electric double-layer capacitor (EDLC) construction coupled with Eaton’s proprietary processes and materials, the supercapacitor module can last for millions of charge/discharge cycles and can be used to replace or augment existing battery systems.

Additionally, the XTM-18 has six supercapacitor cells with an ESR of 22mΩ, 18V operating voltage, and 61.7F combined capacitance. It can be used as a sole energy storage solution or combined with batteries to optimize cost, life, and runtime. System requirements can range from a few microwatts to megawatts and all products have low ESR for high power density with environmentally friendly materials used to make it a green power solution. 

Other features include:

  • Very low equivalent series resistance (ESR)

  • Wide operating temperature range

  • Cost-effective backup power and large energy recapture

  • RoHS, halogen-free, and IP54 compliant 

  • 22mΩ low ESR, 18 V operating voltage, and 61.7F combined capacitance

  • High efficiency (> 98%) under broad operating conditions

  • High-reliability green solution

  • Low operating costs and maintenance-free

  • -40°C and to 65°C operating temperature range (with linear voltage derating to 15V @ 85°C) 


For Use in a Variety of Applications

Potential applications and use cases for the XTM-18 include industrial computers, emergency backup energy, battery assist engines, soft shutdown for industrial robotics and PLCs, automated guided vehicles (e.g. warehouse automation, forklifts), wind turbines, vehicle engines, and material handling equipment.
