3. MAXIMUM TRANSPARENCY
Power Distribution Units (PDUs) ensure maximum energy transparency. They can measure the distributed electrical parameters, but also switch loads and identify environmental influences. This gives administrators an in-depth insight into the conditions in the rack, which simplifies troubleshooting if the worst comes to the worst. The values determined can also help implement energy efficiency measures and reveal usage potential. “Rittal has developed a new generation of PDUs that integrates seamlessly into the modular power distribution and back-up concepts that can be implemented using the RiMatrix NG platform,” explains Kreiling. “Their compact design makes them easy to incorporate into any IT rack in the Rittal portfolio. Tool-free attachment using clips makes installation far easier,” he adds. The power- saving design and low internal energy consumption have a positive impact on the data centre’s energy balance. The PDU controller module and overvoltage protection can even be replaced while the data centre is operational.
The new PDUs are available in five variants that cover all data centre applications. They range from the Basic version for simple power distribution to the Managed version in which measurement and switching takes place output by output. Between these two options, there is also a Metered version for measurement per phase and Metered Plus for measurement per output slot. Besides this, the PDU has four sensors that integrate key monitoring functions.
This gives administrators a permanent overview of parameters such as humidity and temperature as well as personalised access alarms such as door monitoring and locking systems. Meanwhile, those who prefer to use the Rittal Computer Multi Control Systems (CMC III) to monitor environmental parameters can utilise up to 32 sensors to do just that. Thanks to its scalability, the new PDU family from Rittal covers a wide range of requirements. What’s more, these components combine the ultimate in energy and cost efficiency with maximum availability of the entire system. That protects investments and cuts operating costs.
