NSP/RSP Series High-Efficiency Enclosed AC/DC Power Supplies
MEAN WELL power supplies deliver robust performance across a wide range of voltages and power levels for industrial systems
MEAN WELL NSP and RSP series enclosed AC/DC power supplies deliver robust, high efficiency performance across a wide range of voltages and power levels for industrial, automation, and medical systems. Offering single output configurations from 75 W to 3,200 W, these power supplies support wide AC and DC input ranges with active power factor correction and conversion efficiencies up to 94.5%. The established RSP series provides a proven, feature-rich industrial power platform, while the next generation NSP series enhances that foundation with ultra wide input capability, lower no-load power consumption, improved thermal performance, and expanded safety compliance, supporting both legacy designs and modern, energy efficient system requirements.
