SEA Company is the official distributor of MEAN WELL in Ukraine
MEAN WELL RSP-75/100/150/200/320 series power supplies have been successfully used in a wide range of industries for over a decade, from industrial equipment and telecommunications to architectural lighting, security and fire alarm systems. The cumulative volume of shipments has long exceeded 10 million units, confirming their high level of trust in the market.
In 2025, MEAN WELL presented the next generation of these solutions – the NSP-75/100/150/200/320 series. The new models have become more technologically advanced and affordable, combining optimal cost with improved performance.

Compared to their predecessors, NSP power supplies feature more compact dimensions and an extended operating temperature range from –40 to +85°C. Full power is available even at temperatures up to +60°C, which significantly increases the possibilities of use in harsh environments.
The NSP series also complies with a wider range of international standards – for industry, ICT, medical equipment, home appliances and renewable energy – ensuring compliance with modern safety and efficiency requirements, as well as a long service life.
Thus, the NSP series creates a reliable platform for new projects, gradually replacing the RSP line – providing a better price-performance ratio, increased efficiency and expanded functionality.
