Patented technology enhances and simplifies design of 75 to 150W outputs used in modular power supply series

Posted : 25 Sep 2019

TDK Corporation (TSE 6762) announces the addition of the SA modules to the<a href="https://www.emea.lambda.tdk.com/uk/products/product-details.aspx?scid=387"> 550 to 2000W TDK-Lambda branded QM series of AC-DC modular power supplies</a>. The SA modules are available with 5V /15A, 12V /12.5A, 15V /10A and 24V /6.25A outputs and offer a cost-effective solution for low power output requirements.<br /> &nbsp;<br /> The SA module&rsquo;s patented loop control design uses a digital controller and TDK-Lambda developed algorithms. Phase mode control provides higher stability across a wider range of operating conditions. This enhances the output response to sudden load changes, with a faster and improved recovery. The use of a digital controller enables a reduction in component count of 40%.<br /> &nbsp;<br /> Using TDK-Lambda&rsquo;s online Quick Product Finder will automatically optimise the most suitable modules to generate the most cost-effective solution for a customer requirement, and provides a choice of signals, leakage current and standby voltages. Upon entering the desired output voltages and currents, the configurator will automatically produce a short 7-digit code for easy order placement.<br /> &nbsp;<br /> All models in the QM series feature low acoustic noise and full MOPPs isolation. With medical and industrial safety certifications, the QM series addresses a wide range of applications, including BF rated medical equipment, test and measurement, broadcast, communications and renewable energy applications. The QM series is certified to IEC/EN/UL/CSA 60601-1, ANSI/AAMI ES 60601-1, IEC/EN 61010-1 and IEC/EN/UL/CSA 60950-1 with CE marking for the Low Voltage, EMC and RoHS Directives.
