The QS400034 is a 600W single-output AC-DC power supply from the QS series, designed for medical and industrial applications with BF-ready medical isolation (MOPP) and a 7-year warranty. It provides a 12V output at up to 50A, with a 12-13.2V adjustment range, and supports remote monitoring via PMBus™. The unit features a screw terminal input and output connection, forward air cooling, dual AC fuses, and 300µA leakage current. It operates from 90-264Vac, meets IEC/EN 62368-1, IEC/EN 60601-1, and UL/CSA safety standards, and complies with Class B emissions and RoHS. The case size supports standard DIN rail or bench mounting, with dimensions defined by the QS series form factor. The unit achieves up to 91% efficiency at 240Vac and 50% load, with a minimum 10ms hold-up time and automatic recovery under fault conditions.
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.
