NSP-320 320W Enclosed AC/DC Power Supply

The NSP-320 Series combines compact size (179 × 99 × 30 mm) with exceptional versatility, making it suitable for global industrial and medical applications. With 200% peak power capability, a wide operating temperature range (-40°C to +85°C), and low standby power consumption (<0.5W), this series ensures reliable operation with minimal energy waste. Built-in active PFC provides enhanced power quality, while forced-air cooling through a low-noise DC fan (<40 dB) maintains stable thermal performance.

Safety and control features include protections against short circuit, overload, over-voltage, and over-temperature, along with remote ON/OFF control, remote sense, and DC OK signal functionality. The NSP-320 is certified to global safety standards—including IEC/EN 62368-1, 60601-1, 61010-1, and 60335-1—and offers 2 × MOPP compliance and leakage current <350 µA, making it suitable for BF-rated medical devices. With conformal coating, OVC III rating, and operating altitude up to 5000 meters, the NSP-320 delivers exceptional durability even in harsh environments. Backed by MEAN WELL’s 5-year warranty, it’s a cost-effective, high-reliability solution for automation, telecom, medical, and PoE power systems.
