The MDN Midi Power Supplies series from B&R Automation is a modular power-supply family associated with the company’s MIDI I/O hardware platform.
The series is intended to provide the supply function for compact modular control and I/O assemblies rather than to serve as a general standalone power product line. Its role within a MIDI-based system is to support the connected module structure while keeping the installation compact and cabinet-oriented. The original version included several technical and environmental claims that I could not confirm from manufacturer sources. A cleaner product description is that the MDN series is a compact B&R modular power-supply platform for MIDI system integration.
