Description
The MEAN WELL NSP-320 series is a 320W high-reliability AC/DC enclosed power supply designed for multi-industry applications including industrial automation, mechanical equipment, medical devices, security systems, telecommunications, and PoE power sourcing. With a universal 85–305VAC input and built-in active PFC, it delivers up to 93.5% efficiency and extremely low no-load power consumption for enhanced energy savings. The compact 179×99×30 mm design incorporates forced-air cooling with a DC fan, enabling stable performance across a wide operating temperature range from –40°C to +85°C. Featuring 200% peak power capability, constant current limiting, remote ON/OFF control, remote sense, DC OK signal, and fan ON/OFF temperature control, the NSP-320 series ensures dependable performance in demanding environments. It meets a broad range of global safety standards, including IEC/EN/UL 62368-1, 60601-1 (2×MOPP), 60335-1, 61010-1, and 62477-1, making it suitable for BF-rated medical applications and high-altitude installations up to 5000 meters.
