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.
