Measuring just 58.4 x 36.8 x 11.7 mm and boasting an efficiency of 92%, the UWQ series has an ultra-wide 4:1 input voltage range of 18 – 75 VDC around a nominal 48 VDC input. Providing a single output voltage of 12 VDC up to 17A of current with a line regulation of +/-1% and load regulation of +/-1.5%, the UWQ series is idea for applications that require a regulated bus converter. The input to output isolation is certified to 2,250 VDC in accordance with the internationally recognized 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.
