NSP/RSP Series High-Efficiency Enclosed AC/DC Power Supplies

MEAN WELL NSP and RSP series enclosed AC/DC power supplies offer single-output configurations ranging from 75 W to 3,200 W, supporting input voltages from 88 V_AC to 305 V_AC and 120 V_DC to 431 V_DC. With active power factor correction (PFC) and high conversion efficiencies up to 94.5%, they are engineered for reliable operation in harsh environments with a wide temperature range from -40°C to +85°C. Models feature low-profile designs, remote ON/OFF control, remote sensing, and programmable output voltage and current capabilities.

Advanced protection mechanisms include short-circuit (SCP), overload (OLP), overvoltage (OVP), and overtemperature (OTP) safeguards. Select models support peak power delivery up to 200% for short durations, making them ideal for dynamic loads. High-power variants offer intelligent fan speed control, auxiliary outputs, and optional CANBus or PMBus communication interfaces for system integration.

This generation of models introduces expanded safety certifications, enhanced thermal performance, and broader application coverage. These units are designed with reinforced insulation, lower leakage current, and additional compliance for medical and household standards while maintaining the industrial-grade reliability and configurability engineers expect. The result is a more versatile platform that supports both legacy and emerging design requirements.
