Efficiency to 75 % ECONOLINE DC/DC-Converter with 3 year Warranty The REC3-SR/DR series is a low cost converter containing a built in linear regulator to give a regulated, load independent constant voltage output. The converter is designed to run from a regulated supply and is typically used to provide an isolated output or to generate dual rails from a single rail supply. The converters can deliver 140% rated power for short periods of time to cope with applications with large capacitive loads or high start up currents.

Refer to Application Notes E-139 REC3-S_DR/H1 Series ECONOLINE DC/DC-Converter Specifications (measured at TA = 25°C, nominal input voltage, full load and after warm-up) Certifications EN General Safety Report: SPCLVD1212007 EN60950-1:2006 + A11:2009+A1:2010+A12:2011 Notes Note 1: Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second without damage to the converter Note 2: The REC3-R series requires a minimum of 10% load on the output to maintain specified regulation. Operating under no-load conditions will not damage these devices; however, they may not meet all listed specifications.
