Murata Launches 93% Efficient 160 Watt Conduction Cooled AC-DC Supply for Use in Cellular Base Stations

Murata has announced the MVAD160 series of 160 Watt AC-DC power supplies, packaged in an industry standard 2 x 4 inch (50.8 x 101.6 x 38.1 mm) format and designed for use in next-generation high-speed compact base station equipment. Accommodating the universal AC input of 85 - 264VAC, the series comprises three output models providing the nominal main output (V1) of +12, +24, or +48 VDC and an optional auxiliary output (V2) of 5VDC at 0.1A. With efficiencies up to 93%, these power supplies have structure-supported conduction cooling, and comply with no-load power consumption of less than 0.3 Watt.

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

Designed for use in cellular infrastructure equipment such as small cell base stations that need to endure a wide range of outdoor operating temperatures, the MVAD160 can operate across the range of -40 to +85°C.

The series complies with the internationally recognized safety approval standards IEC 60950 and IEC 60601 that certify use in IT, industrial, medical, and healthcare equipment.
