The E48SH converter operates from an Positive On/Off logic input voltage of 36V to 75V and is available in output voltages from Open frame/Heat-spreader External Synchronization 1.0V to 15V. Efficiency is up to 92.0% for 3.3V output at 30A full load. Output OVP latch mode With creative design technology and optimization of component Output OCP latch mode placement, these converters possess outstanding electrical and thermal performance, as well as extremely high reliability under highly SOLDERING METHOD stressful operating conditions. All models are fully protected from abnormal input/output voltage, current, and temperature conditions. Wave soldering The E48SH Series converters meet all safety requirements with basic Hand soldering insulation.
