Press release date: March 1, 2014

Hoofddorp, Netherlands – Murata today announced the UWQ 240 Watt quarter-brick DCDC converter from Murata Power Solutions designed for a wireless backhaul, smart grid, and a broad range of networking and other telecommunications applications. With a fixed 12 VDC / 20 A single output this DOSA compatible open-frame quarter brick package occupies only 58.4 x 36.8 x 11.7 mm. This compact device helps designers conserve valuable board footprint for today’s space-constrained designs. The converter accepts a wide 3:1 input range of voltage from 18 to 60 VDC around a nominal 48 VDC. A remote sense feature provides the automatic adjustment of Vout to make up for line and load losses while a trim function allows +/-10% of Vout. The series has tight load and line regulation that ensures that the output voltage does not vary beyond +/- 1.25% when the load changes.

The UWQ-12/20-T48 has a typical efficiency of 92% and up to 3 units can operate in parallel in order to provide redundancy or load sharing of a higher power requirement.

Controls include remote On/Off control of either negative or positive logic. In addition, the converter has a number of protection features including overcurrent, overtemperature, input undervoltage and output short circuit.

The UWQ converter is designed to operate in environments ranging from - 40 to + 85 degrees C. Input to output isolation is 2,250 VDC with a Basic insulation system to meet industry safety requirements. An optional baseplate is offered to suit conduction cooled applications.
