  • Din Rail Power Supply

    DIN rail power supplies

    DIN rail power supplies are very popular with panel, machine and cabinet builders. Mean Well offers DIN rail power supplies that meet all of the industry standards. The power supplies we offer range from 10 W single phase to 1kW three-phase types. These types have a very wide input range and are suitable for IT, TN or TT systems with triangular or star shaped connections. DIN rail power supplies are normally available for O (Omega), C, or G profiles.

    AC/DC DIN Rail Power Supplies

    Mean Well's range of AC / DC DIN Rail power supplies always offers the right solution for professional cabinet- and application builders. You can choose between a plastic or metal housing, an extra slim design, from among a wide input range and for parallel or redundant applications. The right solution for all your DIN rail power supply needs!

    DC/DC DIN Rail mounting

    Cabinet builders often work with a 24VDC bus which circulates around the entire cabinet. Whenever a 12VDC is required, for example, when supplying power to a camera, no special PCB is in place for a DC/DC PCB converter. Under these circumstances, a DC/DC converter that can be clicked onto a DIN rail is the obvious solution. Mean Well therefore has a wide range of DC / DC DIN rail converters, ranging from 15 Watts to several kW. Trains are supplied almost exclusively with DC/DC converters, often in the form of 19” rack units, but also in the form of DIN rail converters which are clicked on. For this sector Mean Well, of course, has solutions that comply with the famous EN50155 standards used for railways.
