Delphi Series L36SA, 2 x 50W Family DC/DC Power Module 18~75V in, 12V/4A out The Delphi Series L36SA, 2” x 18~75V input, single output, isolated DC/DC converter is the latest offering from a world leader in power systems technology and manufacturing - Delta Electronics, Inc. This L36SA series provides up to 50 watts of power or 15A of output current 3.3V in an industry standard 2” x form factor and pinout. The Delphi L36SA series operates from a wide 18~75V 4:1 input voltages. With creative design technology and optimization of component placement, these converters possess outstanding electrical and thermal performances, as well as extremely high reliability under highly stressful operating conditions. All models are fully protected from abnormal input/output voltage, current, and temperature conditions. The Delphi Series converters meet all safety requirements with basic insulation.
