Power modules for a printed circuit board with screw contacts of the IRM-30 series from MEAN WELL


AC/DC type AC/DC converters are one of the most common types of converters in the power supply. Depending on the purpose of the end device, its dimensions, operating characteristics, and so on, the widest possible range of AC/DC converters of various sizes and power is required. One of the popular types is small-sized modular converters installed on a printed circuit board or in the housing of a final device or device.

IRM-30 series converters are modular AC/DC converters for installation on a printed circuit board. The housing of the IRM modules is made of plastic, and has a full silicone filling to improve heat dissipation, which also provides anti-vibration protection and reliable protection from dust and moisture. A feature of the IRM-30 series is the presence of a modification with screw terminals – IRM-30ST, which creates additional convenience in use, since the module housing can be placed not only on a printed circuit board, but on almost any convenient surface.

IRM-30 modules are an effective solution for providing power to individual circuit nodes that require power supply independent of the main circuit, with galvanic isolation, miniature size and high energy density. The modules have high reliability and low cost.
