The QS4000BD is a 600W single-output AC-DC power supply from the QS series, designed for medical and industrial applications with BF-ready isolation (MOPP), 90-264Vac input range, and PMBus™ communication capability. It delivers 24V at up to 25A with a 24-26.4V adjustable output range, 4% output voltage regulation, and <1% transient deviation. The unit includes output good and inhibit signals, remote sense, and supports hold-up of 10ms. It operates from -20°C to 70°C, with derating above 50°C, and meets IEC/EN 60601-1, IEC/EN 62368-1, and safety standards for medical use. Cooling is provided by a low-noise, variable-speed fan (F type), with screw terminal inputs and outputs, and dual AC fuses. Efficiency reaches up to 91% at 240Vac and 50% load.
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.
