Over 15 years experience of providing support of MEAN WELL Power Supplies
NSP-750-5
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 applications is the NSP-750-5 designed for?
The NSP-750-5 is intended for demanding B2B applications such as industrial automation, telecommunications, PoE power systems, mechanical equipment, medical devices, and home automation. Its high-reliability design, low leakage current, and broad safety approvals make it a strong fit for regulated and mission-critical environments.
What are the main output specifications of the NSP-750-5?
This model provides a 5V DC output at up to 100A, with a rated power of 500W. It is part of Mean Well's NSP-750 series and is designed for low-voltage, high-current applications that need stable DC power in a compact enclosed form factor.
What input range does the NSP-750-5 support?
The NSP-750-5 supports a universal input range of 85-305VAC or 120-431VDC. It also includes active power factor correction, which helps it operate efficiently across a wide range of industrial and commercial power environments.
Can the NSP-750-5 operate in harsh or high-temperature environments?
Yes. The NSP-750-5 is rated for operation from -40°C to +85°C, with derating above +60°C, and it uses forced-air cooling with a temperature-controlled DC fan. The conformal coated PCB and high-altitude rating of up to 5000 meters also support use in demanding environments.
What protection and monitoring features are included in the NSP-750-5?
The NSP-750-5 includes short circuit, overload, overvoltage, and overtemperature protection, along with constant current limiting. For system monitoring and control, it also provides remote ON/OFF, remote sense, auxiliary outputs, and a DC OK signal.
Is the NSP-750-5 suitable for medical or high-reliability equipment?
Yes. This model is part of a series with very low leakage current below 350uA and 2 x MOPP medical safety compliance, which supports use in medical and other high-reliability applications. It is also certified to multiple industrial, medical, household, and energy-conversion safety standards.
