The QS50012N is a 600W single-output AC-DC power supply from the QS series, designed for medical and industrial applications with BF-ready isolation meeting 2 x MOPPs per IEC 60601-1-2. It provides a 12V output at up to 50A, with an input voltage range of 90-264Vac and 47-63Hz frequency. The unit features PMBus™ communication, remote sensing, and an inhibit/enable signal option as standard. It operates from -20°C to 70°C with a derating of 2.5% per °C above 50°C, supports a 10ms hold-up at full load, and complies with EN60601-1, IEC62368-1, and Class B EMI emissions. The case measures 127 x 95 x 30mm with screw terminal connections, and fan cooling is variable speed. Efficiency reaches up to 91% at 240Vac and 50% load. Overvoltage, overcurrent, and short circuit protections are provided with auto-recovery.
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.
