Murata Power Solutions introduces the UWE series of highly efficient 100 – 120 Watt open frame isolated DOSA-compatible eighth-brick DC/DC converters. Using the industry standard through-hole package, measuring 58.42 x 22.86 x 9.91 mm (2.3 x 0.9 x 0.39 inches), the single output units offer the nominal outputs of 3.3, 5 or 12 VDC. Providing an efficiency of typically 91.5% means that for most applications no forced airflow is required. Suiting embedded computing applications and instrumentation subsystems, the converters accommodate an ultra-wide 4:1 input voltage range from 18 to 75 VDC around a nominal 48 VDC. Line regulation is kept within +/- 0.25% Vout and load regulation is maximum +/- 0.2% Vout across the complete range. On-board remote sense inputs compensate for line voltage errors at high output currents. A trim function provides the ability to adjust outputs +/- 10% of nominal output voltage in order to compensate for line losses.

A remote on/off input, negative or positive, provides the ability to remotely control the converter such as required to schedule load startup. The UWE series can operate from –40 °C to +85 °C. Input to output isolation is 2,250 VDC. Protection features include input under voltage, output short circuit, over current and over temperature. An optional baseplate is available for conduction cooled applications.
