Modular AC-DC power supplies

23 October 2019 Power Electronics / Power Management

TDK announced the addition of the SA modules to the 550-2000 W TDK-Lambda branded QM series of AC-DC modular power supplies. The SA modules are available with 5 V/ 15 A, 12 V/ 12,5 A, 15 V/ 10 A and 24 V/ 6,25 A outputs and offer a cost-effective solution for low-power output requirements.

The SA module’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%.

Using TDK-Lambda’s online Quick Product Finder will automatically optimise the most suitable modules to generate the most cost-effective solution for a customer’s 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.

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.
