Product Description

The MDNT42-1 delivers reliable power conversion within machinery cabinets and industrial control panels thanks to its rack-mounted MIDI form factor. As part of the trusted MDN series, it outputs a regulated 24VDC at 20W continuous to efficiently drive control panel components and I/O modules. With compact measurements similar to a rack PCB, its space-saving design allows maximizing utilization while minimizing required rack units.

Outstanding integration stems from straightforward mounting via included clip nuts compatible with standard MIDI rails. Quick assembly uses common #6-32 rack screws to firmly secure the supply without compromising design simplicity. Minimal dimensions further lend themselves to tight-packed panel builds where cubic centimeters make a difference. Mass terminations are similarly ruled out in favor of modular hardwiring.

Smooth ripple-free power under load is ensured by an output rating indicating 0.8A continuous capacity. Typically less than 100mV of noise or oscillation aids compatibility with sensitive electronics. Dual LEDs provide positive status indication, with green confirming normal operations and red warning of overloads or faults. This improves remote troubleshooting without opening enclosure doors. Ruggedness suitable for industrial settings is demonstrated through testing for factors like shock, vibration, and temperature variation encountered in machinery environments. However, for portable applications, the fixed mounting base recommends securing with alternate fixings like optional DIN rails or panel retention to prevent movement during transport.
