NSP-750-12

The NSP-750-12 is a 750W enclosed AC/DC power supply with a 12V DC output. Its rated output current is 65.5A, making it suitable for high-current 12V industrial and system-level applications. This model is part of Mean Well's high-reliability NSP-750 series.

Mean Well positions the NSP-750-12 for demanding multi-industry use, including industrial automation, telecommunications, PoE power sourcing, medical equipment, mechanical systems, and home automation. Its high power output, remote control features, and DC OK signal make it a fit for monitored and integrated power systems. The 12V version is best considered where a regulated 12V supply with substantial current capacity is required.

Yes, this model is built for challenging operating conditions. It supports an operating temperature range from -40°C to +85°C, uses a conformal coated PCB, and is rated for high-altitude installation up to 5000 meters under the stated overvoltage categories. Derating applies above +60°C, so performance planning should account for elevated ambient temperatures.

The NSP-750-12 includes short circuit, overload, overvoltage, and overtemperature protection, along with constant current limiting. It also provides a DC OK signal for system monitoring, remote ON/OFF control, and remote sense for output compensation. These features support higher-reliability use in monitored industrial and medical-related equipment designs.

Compared with basic enclosed power supplies, the NSP-750-12 stands out for its broad 85-305VAC input range, active PFC, up to 95% efficiency, and 200% peak power capability for up to 5 seconds. It also adds higher-end control and monitoring features such as remote ON/OFF, remote sense, auxiliary outputs, and DC OK signaling. The series is aimed at higher-reliability applications rather than general low-cost power conversion.

This model includes very low leakage current below 350 microamps and carries 2xMOPP medical safety approval, with BF-rated compliance noted in the product details. It is also listed to multiple industrial, household, medical, and energy-conversion safety standards. That makes it relevant for compliance-sensitive equipment where certified power hardware is important.

The NSP-750-12 uses forced-air cooling with a built-in temperature-controlled DC fan. Its compact enclosure measures 199 x 105 x 41 mm and weighs 1.23 kg. This combination supports high power density while keeping the unit suitable for enclosed equipment builds that need a slim 750W power supply.
