Product Information
Extended Description
7030050 Rittal: DK CMC III Power Unit, For power supply and controlling IT equipment via CMC III, Input: C14 100-230 V, 10 A 50/60 Hz, Output: 2x C13, 100-230 V, in total up to 10 A, 50/60 Hz
Article number
DK 7030.050
Product description
The input is switched to the outputs via two relays. In this way, the outputs can be linked to measured values for automatic switching. Fan regulation is one example of a potential application. Manual switching via the CMC III operating interface is likewise supported. Each output is monitored individually, and various values are measured. Cannot be operated with the Processing Unit Compact.

FAQs
The DK CMC III Power Unit is designed for IT equipment power supply and control within cabinet environments using the CMC III system. It provides two switched C13 outputs and a C14 input, with CAN bus connectivity for remote monitoring. When integrating with existing cabinets, ensure the system layout supports the 100–230 V supply and does not require the Processing Unit Compact, as noted in the product guidance.
This unit features two switched IEC 320 C13 outputs that can be fed from a 100–230 V input, with a total load capacity up to 10 A (50/60 Hz). The compact design allows direct power distribution to IT equipment and peripherals in a cabinet, supporting energy management through automatic switching based on measured parameters.
No. The DK CMC III Power Unit is not operable with the Processing Unit Compact. For configurations requiring Processing Unit Compact, you should select compatible components or upgrade the system to a model that explicitly supports that combination, ensuring power, signaling, and CAN bus integration are maintained.
The power unit ships with assembly parts for mounting on surfaces, and its plug-and-play design enables fast connection and automatic detection on the CAN bus network. This reduces commissioning time, enhances reliability for IT infrastructure in cabinets, and simplifies upgrades or expansions in data centers and industrial automation closets.
Plan for 0 to 55 °C ambient temperatures and 5–95% non-condensing humidity. The unit operates on 110–230 V and includes a 10 A pre-fuse. It supports up to 1,000,000 kWh energy measurement range and provides two switched outputs, making it suitable for rugged cabinet environments while maintaining regulatory compliance through standard enclosure materials and mounting options.
