MDR-40-12 Industrial Switching Power Supply 12V 3.33A 40W 85% Efficiency with 85-264VAC/120-370VDC Wide Input

The MDR-40-12 industrial-grade switching power supply delivers 12VDC/3.33A output with 40W maximum power capacity. Engineered for demanding applications, it accepts wide input voltages (85-264VAC or 120-370VDC) and operates at 47-63Hz frequency. Featuring 85% conversion efficiency and ±1.0% voltage accuracy, it maintains stable performance with minimal heat dissipation. The adjustable output voltage (12-15V) accommodates various load requirements while maintaining <120mVp-p ripple noise for precision electronics. Built with industrial durability, it offers 500ms cold-start capability, 20ms hold-up time at full load, and protection against overload/short-circuit conditions. The unit complies with <1mA leakage current standards and withstands 30A/60A inrush current at 115VAC/230VAC inputs. Its compact DIN-rail mountable design (compatible with TS-35/7.5 rails) optimizes space in control panels for factory automation, process control systems, and communication infrastructure. With operating temperatures of -25℃ to +70℃ (derating above +50℃) and IP20 protection, it's ideal for LED displays, security systems, and test equipment requiring reliable power conversion.
