The QS series comprises up to 1200W single-output AC-DC power supplies designed for medical and industrial applications, featuring BF-ready medical isolation rated as 2 x MOPPs with reinforced input-to-output isolation of 4kVac/5.7kVdc. Units operate from 90-264Vac input at 47-63Hz, deliver up to 91% efficiency, and support remote sensing with a ±10% output voltage adjustment range. They provide 10ms minimum hold-up time, hiccup-mode overcurrent and short-circuit protection, and standard signals for output good and inhibit functions. Temperatures range from -20°C to 70°C operational with derating above 50°C, and units comply with IEC/EN 62368-1, UL62368-1, IEC/EN 60601-1, and RoHS standards. Immunity meets EN61000-4-2 to EN61000-4-6 at Levels 3 or 4, with Class B emissions per EN55011/32. Units feature screw-terminal inputs and outputs with variable speed forward air cooling, and a 7-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.
