The input voltage range is from 9-53VDC, and the output voltage is trimmable from 3.3-16.5VDC via a fixed trim resistor. Typical applications for these highly compact, reliable converters include distributed power architecture voltage conversion from 12, 24, 28, Open Frame 36, and 48V bus systems for industrial, medical, test and measurement, and telecom equipment. With an efficiency up to 98%, the converter operates at temperatures from -40C to +85C and comes Single Output with RECOMs standard 3 year warranty.
