The QM4 series is a modular AC-DC power supply designed for medical, industrial, and communications applications, offering 550W or 650W output power with input voltage ranges of 90-264Vac or 180-264Vac respectively. It features 2 x MOPP medical isolation, a low-noise fan for enhanced user experience, and supports up to 10 output modules in a 4-slot chassis with screw terminal connections. The unit operates from -20°C to 70°C with derating above 50°C, complies with IEC/EN 60601-1 and IEC/EN 62368-1 safety standards, and meets Class B EMC emissions with optional Class A for low-leakage configurations. It includes PMBus™ communication, over-temperature, over-voltage, and short-circuit protections, and carries CE, UKCA, and CB certifications under ISO9001 and ISO13485 quality management systems.
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.
