SCWN03 and DCWN03 series are DC/DC converters in DIP package on printed circuit board from MEAN WELL

06.06.2022

DC / DC converters represent a fairly large and actively developing segment of the power supply market. In continuation of the consideration of DC / DC converters of a modular type, we present two new series from MEAN WELL, fully compatible with similar converters from other manufacturers both in overall dimensions and in the location of contacts and their names (Pin-to-Pin compatible).

DC/DC converters of SCWN03 series and DCWN03 series are a series of converters of modular type, with the arrangement of contacts in two rows (DIP24 package), stabilized (Regulated), for installation on a printed circuit board. The SCWN03 series module is a DC/DC converter with a single output of positive polarity, and the DCWN03 series module is a DC/DC converter with a double output, positive and negative polarity of the same rating. The SCWN03 and DCWN03 modules are an effective solution for supplying power to additional (auxiliary) circuit nodes that are demanding on the stability of the supply voltage, with galvanic isolation from the main power source.
