NSP-750-48
Description
Description
The MEAN WELL NSP-750 series is a 750W high-reliability AC/DC enclosed power supply engineered for industrial, medical, automation, telecommunications, PoE power sourcing, mechanical equipment, and home automation applications. With a universal 85–305VAC input and built-in active PFC, it delivers up to 95% efficiency and extremely low no-load power consumption under 0.75–1W depending on model. The compact 199×105×41 mm design incorporates forced-air cooling with a built-in temperature-controlled DC fan and supports 200% peak power capability for up to 5 seconds. The NSP-750 series features constant current limiting, wide operating temperature from –40°C to +85°C, remote ON/OFF, remote sense, auxiliary outputs (5V/12V), and a DC OK signal for system monitoring. With extremely low leakage current (<350µA), 2×MOPP medical safety approval, and certifications across ITE, medical, household, industrial, and energy-conversion standards, it offers robust performance for demanding multi-industry applications and high-altitude installations up to 5000 meters.

Frequently Asked Questions
What output does the Mean Well NSP-750-48 provide?
The NSP-750-48 is a 48V AC/DC enclosed power supply rated for 15.7A output current. Its listed power rating is 753.6W, making it suitable for higher-power industrial and OEM applications that require a regulated 48V supply.
What types of applications is the NSP-750-48 designed for?
This model is intended for demanding multi-industry use including industrial automation, medical equipment, telecommunications, PoE power sourcing, mechanical equipment, and home automation systems. Its high-reliability design, DC OK signal, auxiliary outputs, and remote control features make it a strong fit for integrated equipment builds.
What input range does the NSP-750-48 support?
The NSP-750-48 supports a universal input range of 85 to 305VAC, and it also accepts 120 to 431VDC input. That wide range helps simplify deployment across different regions and power environments in commercial and industrial applications.
Is the Mean Well NSP-750-48 suitable for harsh industrial environments?
Yes. The NSP-750-48 is rated for operation from -40°C to +85°C, with derating above +60°C, and it uses a conformal coated PCB for improved environmental resistance. It is also specified for high-altitude installations up to 5000 meters under the stated overvoltage category conditions.
Does the NSP-750-48 include monitoring and control features for system integration?
Yes. This model includes remote ON/OFF control, remote sense with up to 0.3V compensation, a DC OK signal for status monitoring, and auxiliary outputs. Those features are useful in OEM, automation, and control-panel designs where system feedback and centralized control matter.
How does the NSP-750-48 differ from standard enclosed power supplies?
Compared with more basic enclosed power supplies, the NSP-750-48 is positioned as a high-reliability model with up to 95% efficiency, low leakage current below 350uA, 2xMOPP medical approval, and 200% peak power capability for up to 5 seconds. It is designed for applications that need broader certifications, stronger environmental tolerance, and more integration features than a general-purpose supply.
What protection and safety features are built into the NSP-750-48?
The NSP-750-48 includes protection against short circuit, overload, overvoltage, and overtemperature, along with constant current limiting. It is certified to multiple safety standards including IEC/EN/UL 62368-1 and IEC/EN 60601-1, supporting use across industrial, medical, and other regulated equipment categories.
