100-to-120-Watt eighth-brick DC-DC converters for embedded computing introduced by Murata Power

MANSFIELD, Mass., 11 May 2012. Murata Power Solutions Inc. in Mansfield, Mass., is introducing the UWE series 100-to-120-Watt eighth-brick DC-DC converters for embedded computing applications, instrumentation subsystems, and military embedded systems. The open frame isolated DOSA-compatible power electronics devices provide an efficiency of typically 91.5 percent, which requires no forced-air cooling in most applications.

The UWE series uses industry-standard through-hole package, and measures 2.3 by 0.9 by 0.39 inches, The single-output units offer nominal outputs of 3.3, 5, or 12 volts DC. The device operates in temperatures from -40 to 85 degrees Celsius.

The converters accommodate a 4:1 input voltage range from 18 to 75 volts DC around a nominal 48 volts DC. Line regulation is kept within plus-or-minus 0.25 percent voltage output and load regulation is a maximum of plus-or-minus 0.2 percent voltage output.

On-board remote sense inputs compensate for line voltage errors at high output currents. A trim function provides the ability to adjust outputs plus-or-minus 10 percent of nominal output voltage to compensate for line losses.

Input to output isolation is 2,250 volts DC. Protection features include input under voltage, output short circuit, over current, and over temperature. An optional baseplate is available for conduction-cooled applications.
