Midtronics Cellguard Trace

Alpine Power Systems' experienced technical support & sales team is here to assist your needs:

The Midtronics Cellguard Trace System provides effective string battery monitoring for 24V or 48V battery applications. It is designed to monitor stationary batteries.

Application Markets:

  • Telecommunications
    • Wireline (OSP)
    • Wireless
  • Fire and security alarm systems
  • Broadband
  • Switching and control systems


Rest Assured

Using easy-to-install kelvin connections, the CELLGUARD TRACE measures individual 12-Volt jar conductance, voltage, and temperature every 24 hours. It warns or alarms when any measured parameter crosses a preset threshold. This approach provides early detection of battery degradation, enabling individual jars to be removed from the string prior to full string degradation or system failure.


The Cellguard Trace Features:

  • Simplified installation procedure and economical design 
  • Continuous battery monitoring for improved reliability & cost effective maintenance
  • Identifies infant mortality of batteries that can go undetected
  • Utilizes reliable, field proven conductance technology
