When your application must operate 24/7, efficiency, thermal performance, and safety become critical. The NSP Series is designed for global deployment. It supports an ultra-wide 85–305Vac input range to accommodate diverse mains conditions. High conversion efficiency up to 93.5% and low no-load power consumption further minimizes heat generation and standby losses, helping improve system stability, reduce cooling requirements, and lower total energy waste in real-world installations.

The NSP Series is also engineered for these demanding environments, delivering 75W to 3200W in an AC/DC enclosed type that combines active PFC with a slim, space-efficient form factor for high power density and robust long-term reliability.

Key Advantages of the NSP Series

• Global Multi-Field Certifications & SEMI47 Approval: Compliant with ITE 62368-1, Medical 60601-1, Household 60335-1, Industrial 61558-1 / 2-16 & 61010-1, and Energy Converter 62477-1 for worldwide, cross-industry deployments.
• High Power Density: With an ultra-slim form factor, the NSP Series reduces overall size by 28–46% (model-dependent), freeing space to integrate more functional modules in tight enclosures.
• Inductive/Capacitive Load Capability & OVC III Compliance: Constant-current limiting supports demanding inductive and capacitive loads with 200% peak power capability, while OVC III compliance ensures robust operation in harsh industrial power environments.
• Wide Temperature Range & Low-Noise Cooling: Operates from -40°C to +85°C, with optimized fan acoustics of 30~45 dB (model-dependent).

 

Applications

• PoE for Traffic Light
  The Traffic Control System requires a power supply capable of operating at an ambient temperature of 74°C due to outdoor installation while delivering 480W of output power. The NSP-750 series is the ideal solution, as it supports reliable PoE operation across an extended working temperature range of –40°C to +85°C, ensuring stable performance in harsh outdoor conditions.

 

• Physical Therapy Equipment
  The application Regulatory Standard UL1647 requires a power supply certified to UL 62368 with extra-low leakage current (500 µA) for enhanced safety. This requirement is met by the NSP-500 series, which is Globally certified to 62368-1, 60601-1, 60335-1, 61558-1 / 2-16, 61010-1, and 62477-1, and delivers an extremely low leakage current of less than 350 µA, making it ideal for Therapy Euipment applications.
