Frequently Asked Questions
What applications is the Mean Well NSP-200-12 best suited for?
The NSP-200-12 is designed for industrial, medical, automation, telecom, PoE, security, and home automation equipment that needs a regulated 12V DC output. Its 200.4W rating and 16.7A current capacity make it a strong fit for higher-demand 12V systems where reliability and long operating life matter.
What are the main electrical specifications of the NSP-200-12?
This model provides a 12V DC output rated at up to 16.7A, with a total power rating of 200.4W. It accepts a universal 85-305VAC input range, or 120-431VDC, and includes active power factor correction for efficient operation across global mains conditions.
Can the NSP-200-12 operate in harsh temperature conditions?
Yes. The unit is specified for operation from -40°C to +85°C, with derating required above +60°C. Its fanless convection-cooled design and conformal coated PCB help support use in demanding industrial environments.
Is the NSP-200-12 suitable for medical or high-reliability equipment?
Yes, this model is positioned as a high-reliability power supply and includes IEC/EN/UL 60601-1 medical safety certification with 2xMOPP and BF-rated compliance. It also has very low leakage current below 350uA, which is important for medical and sensitive electronic applications.
How does the NSP-200-12 compare with standard 12V enclosed power supplies?
Compared with many standard enclosed AC/DC supplies, the NSP-200-12 stands out for its wide 85-305VAC input range, high efficiency up to 94.5%, and 200% peak power capability on 12-60V models. It also adds higher-end features such as remote ON/OFF, remote sense, and a DC OK signal for system monitoring.
What protection and monitoring features are built into the NSP-200-12?
The NSP-200-12 includes short circuit, overload, overvoltage, and overtemperature protection. For system-level control and status feedback, it also provides constant current limiting, remote ON/OFF control, remote sense with up to 0.3V compensation, and a built-in DC OK signal.
