93% efficient AC/DC supply for use in cellular base stations

Murata has announced the MVAD160 series of 160W conduction cooled AC/DC power supplies. Packaged in an industry standard 50.8 x 101.6 x 38.1 mm format they are claimed to be designed for use in next-generation high-speed compact base station equipment.

The device features an AC input of 85 to 264Vac, and incorporates three output models providing the nominal main output of 12, 24 or 48Vdc with or without an auxiliary 5Vdc/0.1A secondary output. Energy efficiency is typically said to be in the range of 92 to 93% and the series offers a no-load power consumption of less than 0.3W.

Safety and control features include overcurrent and overvoltage protection together with remote control using a negative logic signal.

The MVAD160 operates across a temperature range of -40 to 85°C, and are also said to be suitable for medical or industrial applications with extended ambient temperature range or where fanless operation at limited physical space is required.
