Rittal CMC III available for sale in the US
Monitoring system receives
UL certification
Rittal Computer Multi Control III (CMC III) has
received UL certification. This means the monitoring
system is now authorised for sale in the US. Its
individual electrical components have been tested by
Underwriters Laboratories (UL), and were found to
comply with the organization’s stringent safety
requirements. Now that the components have been
certified, the system can be sold on the US market.
Herborn, 10. July – Enterprises must provide effective
protection against fire, water, break-ins, and other
dangers facing server enclosures and data centres.
Today, all popular network management systems also
monitor physical parameters and issue alerts in case of
deviation from setpoint values. The CMC III monitoring
system obtains data on these parameters, and passes it
on to the network management system for further
processing. In addition, the CMC III also operates
independently – issuing alerts or notifying predefined
contacts. Thanks to the UL certification, the system can
now be deployed in the US.
CMC III comprises a central Processing Unit (PU). It
interacts with various sensors that measure temperature,
humidity, and other factors within the enclosure. The
sensors are connected to the PU in series via a controller
area network (CAN) bus – keeping cabling to a minimum.
Rittal offers a wide range of sensors and units that can
be connected to CMC III – and customers can tailor their
systems to their specific needs by combining various
components. The solution can be deployed in IT racks,
plus industrial and control enclosures.

Power distribution in server and network racks
The CMC III peripherals range now also includes Power
System Module (PSM), a modular energy distribution
system. It measures all relevant values on the input side
including real power (in kilowatts/kW) and real power
consumed (in kilowatt-hours/kWh). The real power
consumed is measured to an accuracy of 1 per cent. The
PSM includes an element that measures electricity on
the ground wire and detects unbalanced power distribution. An integrated display makes it possible to check
parameters directly at the server and network rack plus
industrial and control enclosures. The rail can be
connected directly to the CMC III, and is available in 16ampere (three-phase) and 32-ampere (single-phase)
