DK7030.050 Rittal CMC III Power Unit For power supply and controlling IT equipment via CMC III

Why Choose the Rittal DK 7030.050 CMC III Power Unit?

The Rittal DK 7030.050 is a compact and intelligent CMC III Power Unit designed for power supply monitoring, measurement and switching of IT equipment within the Rittal CMC III monitoring system. It provides two individually monitored switched outputs, enabling connected equipment such as fans, heaters and other electrical consumers to be controlled manually or automatically.

The Power Unit integrates directly into the Rittal CMC III system via CAN bus and supports plug-and-play automatic detection by the compatible Processing Unit. Its input supply is switched to two IEC C13 outputs through independent relays, allowing the outputs to respond automatically to measured values or configured operating conditions. Manual switching through the CMC III operating interface is also supported.

With an IEC C14 input for 100–230 V AC, 10 A, 50/60 Hz and two switched IEC C13 outputs rated for a combined maximum of 10 A, the DK 7030.050 combines equipment control with detailed electrical monitoring. It measures voltage, frequency, output current, active power and energy consumption, making it suitable for intelligent power management in server racks, data centres and IT infrastructure installations.

Intelligent Power Monitoring and Equipment Control

The Rittal CMC III Power Unit combines electrical measurement with remote and automated switching. Each of its two outputs is individually monitored, allowing operators to observe electrical consumption while controlling connected devices through the CMC III system. This makes it particularly useful where rack cooling, heating or other equipment must respond automatically to environmental or operating conditions.

The unit connects to the CMC III system through its integrated RJ45 CAN bus interfaces and is automatically detected by a compatible Processing Unit. Warning and alarm limits can be configured through the CMC III software, enabling measured electrical values to form part of a comprehensive IT infrastructure monitoring and control strategy. The DK 7030.050 cannot be operated with the CMC III Processing Unit Compact.

Typical Applications

• Data centre and server rack power monitoring.
• Automatic switching and control of rack-mounted fans.
• Control of heaters and other electrical consumers.
• IT equipment power management.
• Energy and current monitoring within server enclosures.
• CMC III environmental monitoring and automation systems.
• Remote equipment switching in network and communications installations.
