The QS7000JT is a 1200W, 48V single-output AC-DC power supply from the QS series, designed for medical and industrial use. It features 2 x MOPP isolation, PMBus control, and a 7-year warranty. Operating from 90-264Vac input, it delivers up to 91% efficiency at 240Vac and 50% load, with a 10ms hold-up at full power. Transient response is within 1% of set voltage for a 50% load step, recovering in 1ms. The unit includes output good and inhibit signals, with protection against overvoltage, overcurrent, short circuit, and overtemperature. It is cooled by a variable-speed fan with forward airflow and uses screw terminals for input and output connections. Rated for -20°C to 70°C operation with derating above 50°C, it complies with IEC/EN 62368-1 and IEC/EN 60601-1 safety standards, and meets EN55032 Class B emissions with 300µA leakage current.
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.
