Murata Power Solutions today announced the introduction of
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 degrees C to +85 degrees 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
