New eighth-brick DC/DC converters target high density embedded applications

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 degrees C to +85 degrees C.

Protection features include input under voltage, output short circuit, over current and over temperature.

An optional baseplate is available for conduction cooled applications.
