System Controller for PMi DC Power Systems

PMi-C is the advanced monitoring and control device for PMi DC Power Systems. It delivers intelligence, an easy user interface and a comprehensive set of features for DC Power System management. PMi-C architecture is based on PowerCAN bus communication and a modular design, which enables excellent system expandability, selectable additional features and flexibility in design. The PMi-C controller is the universal solution for all MIP family DC Power Systems from 24 VDC up to 220 VDC, and for other modules in the family.



PMi-C includes key features such as measurements of the indivi- dual rectifiers (AC input voltage, DC output current and voltage, temperature) as well as battery and load currents. Plug and play support, system parameters upload and download in XML format, PowerCAN-BUS interface to MRC rectifiers and smart peripheral modules as well as inventory management for installed modules.


  • System output voltage measurement
  • DC output current, total rectifiers Functions
  • Energy saving mode with PMi rectifiers
  • Rectifier runtime counter
  • Alarm configuration
  • Real time clock with battery backup
  • Automatic module configuration
