Murata Power Solutions has announced the UWQ series of isolated open frame 204W dc/dc converters packaged in a through hole mount industry standard quarter brick format.
Measuring 58.4 x 36.8 x 11.7mm with an efficiency of 92%, the UWQ series has a 4:1 input voltage range of 18 to 75Vdc around a nominal 48Vdc input. Providing a single output voltage of 12Vdc up to 17A of current with a line regulation of +/-1% and load regulation of +/-1.5%, the UWQ series is suitable for applications that require a regulated bus converter. The input to output isolation is certified to 2250 Vdc in accordance with the internationally recognised safety standard EN/UL60950. Controls include remote On/Off control of either negative or positive polarity. In addition, the converter has a number of protection features including over current, over temperature, input under voltage and output short circuit. Designed for Regulated Intermediate Bus Architectures, typical applications include optical networking applications, wireless base stations and microwave radio communications equipment. An optional baseplate is available for applications requiring conduction cooling. The UWQ series can operate from -40 to 85°C suiting applications in most environments.
