  • Full resistance, battery temperature and voltage monitoring for comprehensive battery state of health analysis (RMS-TA module).
  • String current and ambient temperature monitoring (RMS-TC module).
  • Automatic analysis of battery monitoring data to, identify the batteries that need replacement or maintenance (requires RMS-CM module).
  • All operating parameters can be set via the serial bus.
  • Panel lights indicate when alarm is raised, which can also be read via the serial bus.


  • UPS systems.
  • Data centers.
  • Critical battery backups

RMS-CM. Control Module.

The RMS-CM control module is a front-end module data collection device using ARM technology for comprehensive data processing and communication. RMS-CM can manage up to 6 battery strings and meets Modbus/RTU and SNMP specifications.

Collects front end sensor data, analyzes, stores and uploads the data.
Manages max. 6 strings.
Software monitors battery state 24/7.
Keyboard and LCD display allow user to set parameters and query data directly.
Meets Modbus/RTU and SNMP specifications.


RMS-TA. Voltage, Internal resistance and Temperature Module.

The RMS-TA (RMS-TA-WL, wireless version) Battery Monitoring System is designed specifically for single battery monitoring (2V, 6V, 12V). RMS-TA module advanced technology provides the most comprehensive stationary battery health analysis in the industry.
