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.
