These units are typically single-output, high-efficiency AC/DC converters. They bridge the gap between a simple wall adapter and a lab-grade linear power supply. Unlike cheap consumer bricks, the Elex Top series features active power factor correction (PFC), low ripple noise, and high mean time between failures (MTBF). ericsson elex top
