New 93% efficient 160W conduction-cooled AC/DC supply targets cellular base stations

Murata has introduced the MVAD160 series of 160 conduction-cooled AC/DC power supplies. Packaged in an industry-standard 50.8mm x 101.6mm x 38.1mm format the units are designed for use in next-generation high-speed compact base station equipment. Accommodating the universal AC input of 85 – 264 VAC, the series comprises three output models providing the nominal main output (V1) of +12, +24 or +48VDC with or without an auxiliary 5VDC / 0.1A secondary (V2) output. Energy efficiency is typically in the range of 92% to 93% and the series offers a no-load power consumption of less than 0.3W. 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 -40C to +85C, and also suitable for medical or industrial applications with extended ambient temperature range or where fanless operation at limited physical space is required. Safety and control features include over-current and over-voltage protection together with remote control using a negative logic signal. 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.
