Following the launch of the new-generation NSP-75/100/150/200/320 series, MEAN WELL is expanding the lineup upward with the introduction of the NSP-500/750 series. Compared to the RSP-500/750—products that have been on the market for over 10 years, the NSP-500/750 series offers significantly higher value and comprehensive upgrades: 33% smaller size, higher efficiency, 200% peak power capability, a wider operating temperature range of -40 to +85°C, and an extended 5-year warranty. With certifications covering five major safety categories, the NSP-500/750 series is suitable for industrial automation, communication equipment, security systems, medical applications, smart home devices, new energy systems, and many other fields.
Comparison table of the NSP-500/750 and the previously released RSP-500/750:

Note 1:
The first production batch will not show BSMI/CCC on the label due to later certification timing. These markings will appear in mass production units. During the transition period, MEAN WELL inventory may include different label versions. If BSMI/CCC labeling is required, please contact your MEAN WELL sales representative.
