TDK-Lambda’s MU4 series of modular power supplies features up to 800W output power in a 1U (41mm) high compact package. The product uses a patent-pending intelligent fan control technology to provide extremely low audible noise. The MU4 is covered by a seven-year warranty for a lower cost of ownership.

Accepting an 85 to 264Vac input, the MU4 has a seamless output voltage capability of 3.3Vdc to 104Vdc supplied by five wide-range output modules. The primary option has a 5V standby, fan fail and AC fail signals, remote on/off and PMBus™ communication.

The MU4 has safety certification to the medical IEC 60601-1 and industrial IEC 62368-1 standards and is designed to meet IEC 61010-1. Input to earth isolation is 1 x MOPP (1.5kVac), input to output 2 x MOPP (4kVac) and output to earth is 1 x MOPP (1.5kVac). This full MOPP certification makes it suitable for B and BF equipment. Meeting the EN 55011-B EMC standard makes it easier to integrate for lower cost system compliance.

The flexibility of modular power supplies accelerates development programs while reducing risk. Configuring and selecting products from the MU4 series is straightforward using the online Quick Product Finder, which will automatically produce a 7-digit code to facilitate easy order placement. Applications include medical, test and measurement, factory automation and laboratory equipment, especially those requiring low audible noise.
