The MEAN WELL RSP-75/100/150/200/320 series has been on the market for over 10 years, earning widespread acclaim with cumulative sales exceeding 10 million units. These products have been widely used in industrial control, communication equipment, architectural lighting, security, and fire protection applications. To meet the growing demand for miniaturization and high efficiency, MEAN WELL is now introducing the new NSP-75/100/150/200/320 series.

The all-new NSP series fully surpasses the RSP series with a higher cost-performance ratio: Its dimensions are significantly reduced, and the operating temperature range is expanded to -40~+85℃, with full load operation possible up to +60℃, making it suitable for harsher environments. At the same time, it has obtained safety certifications in multiple industries, including ICT, industrial, medical, household, and green energy applications, ensuring durability and reliability. The NSP series is the true next-generation replacement for the RSP series, offering competitive pricing, extended warranty, and improved cost reduction and efficiency, making it the ideal choice for almost every new design.
 

Comparison table of the NSP-75~320 and the previously released RSP-75~320:


  • Ultra-wide 85~305Vac input is compatible with North America’s 277Vac and less likely to be damaged from unstable AC inputs.
  • High efficiency (90~94.5%) with low no-load power consumption (<0.3W~0.5W, depending on model).
  • 200% peak power output capability.
  • Ultra-wide -40~+85℃ operating temperature range (full load operation at +60℃).
  • Fanless design (NSP-75~200) or built-in low-noise fan <40 dB (NSP-320).
  • Comprehensive protections: short, overload, overvoltage, and overtemperature.
  • Meets OVC III requirements.
  • Suitable for operation at altitudes up to 5000 meters.
  • Programable output voltage.
  • Ultra-low leakage current <350µA; meets 2xMOPP and medical BF-grade applications.
  • Certified for multiple global safety standards: CB/DEKRA/UL/RCM/BSMI/CCC/EAC/BIS/KC/CE/UKCA (Note 1), and IEC/EN/UL 62368-1, 61010-1, 61558-1, 62477-1, and SEMI 47 for semiconductor equipment.
  • PCB with conformal coating for moisture resistance and enhanced durability.
  • 5-year warranty.
 

Note 1:
For the first production batches, BSMI and CCC marks may not appear on the labels due to certification timelines. Labels will be updated in subsequent production batches. During this transition period, MEAN WELL stock may carry different label versions. If BSMI/CCC marks are required, please contact your MEAN WELL sales representative to ensure marking.
