The QM8 is a modular AC-DC power supply series rated for 1200W or 2000W output, designed for medical and industrial use with 2 x MOPP isolation meeting IEC 60601-1. It features 8 slots for configurable outputs, supporting voltages from 2.8V to 105.6V, with up to 18 outputs per unit. Input range is 90-264Vac, 47-63Hz, with >0.95 power factor at 230Vac. Efficiency reaches 91% at 240Vac and 50% load. It includes PMBus™ control, fan cooling (forward or reverse airflow), and over-temperature, over-voltage, and over-current protection. The unit is 270mm wide, 215mm high, and 200mm deep, mounted via eight M4 holes. Operating temperature is -20°C to 70°C, derating at 2.5% per °C above 50°C. It meets IEC/EN 62368-1, UL62368-1, and EN61000-6-3 Class B emissions. A 7-year warranty is provided.
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.
