Converters
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 140ꢀ rated power
for short periods of time to cope with applications with large capacitive loads or high start
up currents.
