More functions, less effort.

Rittal CMC III makes monitoring your IT infrastructure easier than ever.

  • Less cabling and installation effort, thanks to CAN buses
  • Integration of principal sensors as standard
  • Minimal space requirements in the rack

Your benefits with the Rittal CMC III

  • CAN buses (Controller Area Network) mean less effort with cabling and installation
  • Smaller number of modules = Lower costs
  • Only one-third height unit: The compact enclosure saves valuable space inside the rack

  • The principal sensors – control of cold air supply and access sensor – are pre-integrated
  • Redundant power supply is supported, along with Power over Ethernet (PoE)

  • User-friendly commissioning and configuration via a laptop and USB connection
  • Fail-safe, thanks to CAN bus technology

The Rittal CMC III is available in two variants:

Processing Unit Compact
