Features Regulated Converters Low Cost 3W converter in DIP24 Package 1kVDC Isolation Regulated Output UL Approved Continuous Short Circuit Protection Internal SMD design 3 Pinout Options, 3 Case Styles. Efficiency to 7 5 % ECONOLINE DC/DC-Converter Description 3 Watt DIP24 & SMD Single & Dual Output 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.
