MEAN WELL NSP Series: The Compact Successor to the RSP

MEAN WELL launches the NSP series, the new generation of AC-DC power supplies that replaces the trusted RSP series. This range has been developed to meet the growing demand for compact, energy-efficient, and globally certified power supplies for industrial and commercial applications.

The NSP series offers a footprint up to 30% smaller than its predecessor, allowing for easy integration into compact control cabinets and modular systems. Despite its reduced size, the NSP delivers top-level performance with a high efficiency of 90%–94.5%, resulting in lower heat generation and a longer service life for both the power supply and surrounding components. The range includes fanless models from 75 to 200 W for silent, low-maintenance operation and a 320 W version with a quiet fan (< 40 dB) for applications requiring higher output power.

Thanks to its wide input voltage range (85–305 VAC), the NSP series is suitable for various applications — from automation and energy systems to test and measurement equipment. The power supplies are certified worldwide (CB, UL, CE, UKCA, DEKRA, CCC, EAC, KC, RCM, BIS) and comply with multiple safety standards such as IEC/EN/UL 62368-1, 61010-1, 61558-1, and 62477-1. The applied conformal coating protects the electronics against moisture, dust, and condensation, ensuring reliable performance even under harsh conditions.
