Frequently Asked Questions
What is the Mean Well NSP-500-15 designed for?
The NSP-500-15 is a 501W enclosed AC/DC power supply built for demanding multi-industry equipment. It is positioned for applications such as industrial automation, mechanical systems, security equipment, telecommunications, PoE power sourcing, medical devices, and charging equipment. Its high-reliability design makes it a fit for systems that need stable output and broad standards coverage.
What output does the NSP-500-15 provide?
This model provides a 15V DC output with a rated current of 33.4A. Its listed power rating is 501W, which places it in the high-power enclosed supply category for industrial and commercial equipment. It is the 15V version within the NSP-500 series.
What input range does the NSP-500-15 support?
The NSP-500-15 accepts a universal 85-305VAC input and also supports 120-431VDC input. It includes built-in active power factor correction, which helps support efficient operation across a wide input range. This makes it suitable for equipment deployed across varied power environments.
Is the NSP-500-15 suitable for harsh or wide-temperature environments?
Yes. The NSP-500-15 is rated for operation from -40°C to +85°C, with derating above +60°C. It also uses conformal coating on the PCB and is intended for reliable performance in demanding environments.
What makes the NSP-500-15 a high-reliability power supply?
This model combines up to 95% efficiency, low no-load power consumption below 0.75W, and a full protection set including short circuit, overload, overvoltage, and overtemperature protection. It also includes remote ON/OFF control, remote sense, and a DC OK signal for system monitoring. These features support stable operation in applications where uptime and status visibility matter.
Can the NSP-500-15 be used in medical or regulated equipment?
The NSP-500-15 is specified with extremely low leakage current below 350 microamps and 2xMOPP medical safety compliance. It is also certified to standards including IEC/EN/UL 60601-1 and 62368-1, along with additional household, industrial, and energy converter standards. Buyers should still confirm the full end-system compliance requirements for their specific device.
Does the NSP-500-15 support peak power demands?
Yes. In the NSP-500 series, the 12V to 60V models include 200% peak power capability for 5 seconds, up to 1000W. Since the NSP-500-15 is a 15V model, it falls within that peak-power-capable range.
What cooling and physical size should buyers expect from the NSP-500-15?
The NSP-500-15 uses forced-air cooling with a built-in DC fan, with listed noise below 45 dB. Its compact housing measures 199 x 99 x 41 mm and the product weight is listed as 1.0 kg. That combination helps it fit higher-power applications where space efficiency still matters.
