Frequently Asked Questions
What is the output rating of the Mean Well NSP-320-36?
The NSP-320-36 is rated for 320.4W output with a 36V DC output and 8.9A rated current. This makes it suitable for equipment that needs a higher-power 36V enclosed AC/DC supply in industrial and commercial systems.
What kinds of applications is the NSP-320-36 designed for?
This model is intended for multi-industry use, including industrial automation, mechanical equipment, medical devices, security systems, telecommunications, and PoE power sourcing. Its high-reliability design and broad safety coverage make it a fit for demanding OEM and B2B applications.
Does the NSP-320-36 support demanding operating environments?
Yes. The NSP-320-36 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. It is also noted as suitable for high-altitude installations up to 5000 meters under the stated overvoltage category conditions.
What makes the NSP-320-36 a high-reliability power supply?
This model combines active PFC, efficiency up to 93.5%, conformal coating, remote sense, DC OK signal, remote ON/OFF control, and comprehensive protections including short circuit, overload, overvoltage, and overtemperature protection. It also offers 200% peak power capability on 12V to 60V models, which helps in applications with short-duration surge demand.
Is the Mean Well NSP-320-36 suitable for medical or safety-critical equipment?
The NSP-320-36 is certified to IEC/EN/UL 60601-1 and is described as compliant with 2xMOPP for medical BF applications, with leakage current below 350uA. It also meets additional safety standards including 62368-1, 60335-1, 61010-1, and 62477-1, which supports use in regulated professional equipment.
What input range does the NSP-320-36 accept?
This power supply accepts a universal 85-305VAC input range and also supports 120-431VDC input. That wide input capability helps it fit global equipment platforms and installations where supply conditions may vary.
How efficient is the NSP-320-36 and does it help reduce standby power use?
The NSP-320-36 reaches efficiency up to 93.5% and has very low no-load power consumption listed at below 0.3-0.5W. These characteristics can help reduce wasted energy in systems where efficiency and standby performance matter.
What warranty comes with the Mean Well NSP-320-36?
The NSP-320-36 includes a 5-year warranty. For B2B buyers, that adds confidence when specifying it for long-life industrial, medical, or communications equipment.
