The UWE series is a 100-to-120-W, eighth-brick, DC-DC converter 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.
This series uses industry-standard through-hole package, and measures 2.3 x 0.9 x 0.39 in. The single-output units offer nominal outputs of 3.3, 5, or 12 V dc. The device operates in temperatures from -40 to +85ºC.
The converters accommodate a 4:1 input voltage range from 18 to 75 V dc around a nominal 48 V dc. Line regulation is kept within +/- 0.25% 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 +/- 10% of nominal output voltage to compensate for line losses.
Input to output isolation is 2,250 V dc. Protection features include input under voltage, output short circuit, over current, and over temperature. An optional baseplate is available for conduction-cooled applications.
