With the increasing demand for more compact and efficient products, MEAN WELL has launched the new NSP-75/100/150/200/320 series, now available within the extensive OLFER Electronics catalog.
The NSP series represents a significant improvement over the RSP series, offering better value for money. Furthermore, the dimensions have been considerably reduced, and the operating temperature range has been extended from -40°C to +85°C, with full load capacity up to +60°C, making it suitable for more demanding environments.
These devices are certified for safety across multiple sectors, including information and communication technologies, industry, medical applications, residential use, and green energy, ensuring greater durability and reliability.

In short, the new NSP series is the true replacement for the RSP series. It offers more competitive pricing, an extended warranty, and improved performance in efficiency and cost reduction, making it the ideal choice for virtually any new design.
The following table provides a comparison between the NSP-75-320 and RSP-75-320 series.
