Modular power supply delivers up to 1500 W with extremely low acoustic noise

Up to 13 fully isolated output voltages can be easily configured using TDK-Lambda's online Quick Product Finder. Applications include medical, dental, broadcast, professional audio, test and measurement, and industrial equipment that require a low-profile 41 mm height and/or low audible noise.

The MU6's patented intelligent fan speed control circuit uses a microcontroller algorithm to monitor not only the temperature of the primary converter, but also each of the individual secondary modules. This enables the fan speed to be accurately adjusted to provide an optimum audible noise level as low as 36 dBA, even with an 80 % load. This low acoustic noise level improves hospital patient comfort and reduces operator fatigue.

An extensive range of modules is available from 150 W to 1008 W, providing continuous coverage from 3.3 V to 105.6 Vdc. Each module includes remote sense and an output good signal as standard. Options for the MU6 include a 5 V/2 A or 12 V/1 A standby voltage, fan fail signal, inhibit and enable for all outputs, AC fail, PMBus communication, and current share for configurations requiring parallel operation. Providing enhanced flexibility to meet diverse system requirements and simplify the design process.

The MU6 power supplies deliver efficiencies of up to 94 % meaning less energy is lost as heat, resulting in lower operating temperatures and increased reliability. These units can operate continuously in ambient temperatures ranging from -20 degC to +70 degC, with the load linearly derated to 50 % above 50 degC. The earth leakage current is less than 300 uA, including all tolerances, with a touch current of xtagstartz100 uA. A market-leading seven-year warranty is provided as standard, delivering unmatched long-term assurance of product reliability and support, and reinforcing the highest standards of customer confidence in the industry.
