The QS7-1200-48 is a 1200W single-output AC-DC power supply designed for medical and industrial applications, featuring BF-ready medical isolation (MOPP) and PMBus™ communication option. It operates from 90-264Vac input, delivers 48V at up to 25A, and maintains output regulation within 4% across line and load variations. The unit has a maximum turn-on time of 2 seconds, efficiency up to 91% at 240Vac and 50% load, and a 20ms holdup at full power. Cooling is via a low-noise variable speed fan, and it complies with IEC/EN 60601-1, IEC/EN 62368-1, and UL/CSA standards for medical and general use. The product is rated for -20°C to 70°C operation with derating above 50°C, and meets EN61000-4 series immunity and EN55011/32 Class B emissions. The QS7000KY is an order code variant of this model with inhibit and enable signals and a 5V/2A standby supply.
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.
