The NSP series is more than 30% smaller than the previous RSP models, providing greater flexibility in enclosure design and installation. The compact casing leaves more room for other components, reducing housing costs and enabling a more efficient system layout.
Despite its smaller size, the NSP delivers outstanding performance. With efficiency levels from 90% up to 94.5%, it ranks among the best in its class. Less energy loss means less heat generation and a longer lifespan, both for the power supply and for surrounding electronics.
The series includes fanless models (up to 200 W) for completely silent operation, as well as a 320 W version with a quiet fan (< 40 dB) for applications requiring higher power output.
Reliable in Every Condition
Designed for dependable operation in demanding environments, the NSP series performs flawlessly from –40 °C to +85 °C (full load up to +60 °C) and up to 5000 m altitude. It’s the ideal choice for industrial, automation, and energy applications.
Thanks to its OVC III classification, an additional isolation transformer is often unnecessary, simplifying system design and reducing costs. All models are also equipped with conformal coating for protection against moisture, dust, and condensation, ensuring long-term reliability in harsh environments.
