NSP-320-27

The Mean Well NSP-320-27 is a 321.3W enclosed AC/DC power supply built for demanding multi-industry equipment. It is suitable for industrial automation, mechanical equipment, medical devices, security systems, telecommunications, PoE power sourcing, and charging systems where a regulated 27V output is needed.

This model provides a nominal 27V DC output with a rated current of 11.9A. Its power rating is 321.3W, making it a fit for systems that need a higher-power 27V supply in a compact enclosed form factor.

Yes. The NSP-320-27 is specified for operation from -40°C to +85°C, with derating above +60°C, and it uses forced-air cooling with a built-in DC fan for thermal stability. It also has a conformal coated PCB and supports high-altitude installations up to 5000 meters under the stated overvoltage category conditions.

Yes, this series is built for high-reliability applications and includes compliance with IEC/EN/UL 60601-1 with 2 x MOPP. The product description also notes very low leakage current and suitability for BF-rated medical applications, which makes it relevant for certain medical equipment designs.

The NSP-320 series reaches efficiency up to 93.5% and includes built-in active PFC. It also has very low no-load power consumption, listed as below 0.3-0.5W, which helps reduce standby energy use in always-on systems.

This model includes constant current limiting and protection functions for short circuit, overload, overvoltage, and overtemperature. It also provides remote ON/OFF control, remote sense with up to 0.3V compensation, a DC OK signal, and fan ON/OFF temperature control for system-level monitoring and reliability.

The NSP-320-27 is differentiated by its high-reliability design, broad safety certifications, wide operating temperature range, active PFC, and support for demanding industrial and medical-oriented environments. It also offers 200% peak power capability within the NSP-320 series for 12-60V models, which can be useful in applications with short-duration peak load demands.
