The TDR-480 Series from Mean Well are Three-Phase AC-DC Power Supplies that convert AC input voltage of 340-550 V to DC output voltages of 24-48 V. These converters deliver an output power of 480 W, an output current of up to 20 A, and offer an efficiency of 92.5%. They are equipped with active Power Factor Correction (PFC) and offer protection against short circuit, overload, over-voltage, and over-temperature events. These convection-cooled converters incorporate a constant current-limiting circuit and have industrial-grade certifications proving their durability. They are available in DIN-rail packages that measure 128.5 x 125.2 x 85.5 mm and are suitable for industrial control systems, semiconductor fabrication equipment, factory automation, and electromechanical apparatus.
