MEAN WELL RSP-500-12 DC Power Supply 500W/12V/42A PFC for CCTV, Computer Project,LED Strip Light, Router

The RSP-500-12 is a high-efficiency 12V industrial-grade switching power supply designed for demanding applications. With a rated output of 12V DC and 41.7A current, it delivers 500W continuous power (550W peak) with 88% typical efficiency. Featuring universal AC input (85-264VAC) and wide DC input compatibility (120-370VDC), it operates across 47-63Hz frequencies with >0.94 PF at 230VAC. The unit offers precise voltage regulation (±3% accuracy) with adjustable output range of 11.4-12.6V, maintaining ±0.5% line regulation and ±1% load regulation. Advanced cooling options include 25CFM forced air cooling for full 500W operation or natural convection (320W). Built with industrial durability, it features <200mVp-p ripple noise, cold-start surge protection (40A/115VAC), and multiple safeguards: over-current (105-130% current limiting), over-voltage, and over-temperature protection with auto-recovery. The compact design supports chassis-mount configurations (-C/TF/SF variants) and provides 10ms holdup time at full load. Meets strict safety standards with <2mA leakage current and <100µA contact current. Ideal for factory automation, telecom systems, LED arrays, and high-current equipment requiring stable DC power in harsh environments. Technical highlights include 91% efficiency (230VAC input), <30ms startup time, and -20°C to +70°C operation with derating above 50°C. Package includes power good signal and remote sense capability for system integration.
