Description
Description
The MEAN WELL NSP-500 series is a 500W high-reliability AC/DC enclosed power supply designed for demanding multi-industry applications, including industrial automation, mechanical systems, security, telecommunications, PoE power sourcing, medical devices, and charging equipment. Featuring a universal 85–305VAC input with built-in active PFC and efficiency up to 95%, it provides stable, energy-efficient performance with low no-load consumption under 0.75W. The compact 199×99×41 mm housing integrates forced-air cooling with a DC fan, 200% peak power capability, remote control, remote sense, and a DC OK signal for enhanced system monitoring. With extremely low leakage current (<350μA), 2×MOPP medical safety compliance, and certifications across ITE, medical, household, industrial, and energy converter standards, the NSP-500 series delivers robust, reliable operation in harsh environments and wide temperature ranges from –40°C to +85°C.

Frequently Asked Questions
What applications is the Mean Well NSP-500-48 best suited for?
The NSP-500-48 is designed for demanding multi-industry systems that need a regulated 48V DC output at up to 10.5A. Based on its feature set and certifications, it is well suited for industrial automation, telecommunications, PoE power sourcing, security equipment, medical devices, mechanical systems, and charging equipment.
What are the main output specifications of the NSP-500-48?
This model provides a 48V DC output with a rated current of 10.5A and a power rating of 504W. It is part of Mean Well's NSP-500 high-reliability enclosed power supply series for applications that need substantial continuous power in a compact form factor.
Can the NSP-500-48 operate in harsh temperature conditions?
Yes. The specified operating temperature range is -40°C to +85°C, with derating required above +60°C. That makes it suitable for demanding environments where standard commercial power supplies may have a narrower operating window.
How does the NSP-500-48 compare with standard enclosed power supplies for efficiency and reliability?
The NSP-500-48 is positioned as a high-reliability model with efficiency up to 95%, low no-load consumption below 0.75W, active PFC, and a conformal coated PCB. It also includes remote control, remote sense, and a DC OK signal, which are useful features in monitored industrial and mission-critical systems.
Is the NSP-500-48 suitable for medical or low-leakage applications?
This model is specified with leakage current below 350μA and 2×MOPP medical safety compliance. Those characteristics make it a strong candidate for medical-related equipment and other applications where low leakage current and enhanced safety standards matter.
Does the NSP-500-48 support system monitoring and control functions?
Yes. The unit includes remote ON/OFF control, remote sense with 0.3V compensation, and a DC OK signal. These features help OEMs and system integrators monitor output condition and manage the power supply within larger equipment platforms.
What protections and overload capability does the NSP-500-48 include?
The NSP-500 series includes short circuit, overload, overvoltage, and overtemperature protection. For 12V to 60V models, including the 48V version, the series also supports 200% peak power capability for 5 seconds, allowing short-duration load surges up to 1000W.
