The XMS50070 is a 500W AC-DC power supply in an open-frame configuration with a 24V output at 20.8A, designed for medical, industrial, and broadcast applications. It features reinforced 2 x MOPP isolation (5.7kVdc, 4kVac), Class I construction with earth leakage current under 150µA, and meets EN61000-3-2 and EN55011 Class B emissions standards. It supports remote on/off, AC fail detection, and includes a 5V/2A standby supply. The unit operates from 90-264Vac input, achieves up to 92% efficiency at 230Vac, and has a hold-up time of 16ms. It offers over-voltage, over-temperature, and short-circuit protection with auto-recovery. Operating temperature range is 0°C to 50°C with sufficient airflow, and it complies with IEC/EN 60601-1, IEC/EN 62368-1, and ISO13485 standards. A top fan version is available, but this model uses a U-chassis with convection cooling. The product carries a 5-year warranty.
AC-DC converters have the functionality to extract a stable DC power supply by rectifying and controlling commercial power supplies. TDK offers an abundant lineup of TDK-Lambda brand AC-DC switching power supplies that adopt the "switching method" for the industrial equipment market. These power supplies are available in unit types, PC board types, power module types, on-board types, and DIN rail mount types, with a wide-ranging product lineup from models with a small capacity of several W to models with a large capacity exceeding 2 kW. TDK-Lambda offers "standard power supplies" that meet the various needs of its customers for keeping up with the changing times, including miniaturization and efficiency enhancement, compliance with safety standards, support for wide input, compliance with EMI (electromagnetic interference) standards and higher harmonic current regulation, compliance with the RoHS directive, and the adoption of digital control technologies.
