New NSP Series – Compact, Efficient, and Ready for Any Challenge

For over a decade, the MEAN WELL RSP-75/100/150/200/320 series has earned widespread recognition across industries – from industrial automation and telecommunications to architectural lighting, security, and fire protection systems. To meet the growing demand for miniaturization and higher efficiency, we are introducing the new NSP-75/100/150/200/320 series.

The NSP series sets a new benchmark, offering a much better cost-performance ratio than the previous RSP line. The power supplies are more compact and feature an extended operating temperature range of –40°C to +85°C, with full load operation up to +60°C, making them suitable for harsh environments.

The new models have obtained a wide range of safety certifications for industrial, ICT, medical, household, and green energy applications, ensuring outstanding reliability and durability. With competitive pricing, an extended 5-year warranty, and improved cost and energy efficiency, the NSP series is the ideal choice for almost any new design.

Key Features of the NSP Series:

• Ultra-wide 85–305 VAC input, compatible with North American 277 VAC and resistant to unstable AC inputs.
• High efficiency (90–94.5%) with very low no-load power consumption (<0.3–0.5 W).
• 200% peak power capability for applications requiring short-term overloads.
• Wide operating temperature range –40 ~ +85°C (full load up to +60°C).
• Fanless design (NSP-75~200) or low-noise fan <40 dB (NSP-320).
• Comprehensive protections: short circuit, overload, overvoltage, and overtemperature.
• OVC III compliant, suitable for operation up to 5000 m altitude.
• Programmable output voltage and ultra-low leakage current <350 µA, meeting 2×MOPP and BF medical grade standards.
• Certified globally: CB, DEKRA, UL, RCM, BSMI, CCC, EAC, BIS, KC, CE, UKCA; compliant with IEC/EN/UL 62368-1, 61010-1, 61558-1, 62477-1, and SEMI 47.
• Conformal coating on PCB for moisture resistance and enhanced durability.
• 5-year warranty across all models.

Combining high reliability, versatility, and competitive pricing, the NSP series is the true next-generation successor to the RSP line – ready to power any modern design.
