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.

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 require a minimum of 10% loading on the output to maintain specified regulation. Operating under un-load
condition will not damage these devices, however they may not meet all listed specifications.
