Myrra 47000 Series AC/DC Switch Mode Power Supply
Myrra encapsulated electronic transformers 47000 series are switched mode power supplies which offer increased power, and energy saving characteristics due to high efficiency. They are suitable alternatives to linear transformers in all AC/DC applications up to 5W power rating, and are an alternative to DC/DC converters for DC current applications. Within the same footprint as an EI30 transformer they will replace a 50Hz transformer, fuse, bridge rectifier, and filtering capacitor, enabling upgrade of your application without the need for PCB redesign.
Single output types available regulated or unregulated.
Two output types are regulated and either common output (838-143 to 838-147),
or isolated output (838-152 to 838-158).
Input voltage 85-265 Volts AC; 85-370 Volts DC.
Input frequency 47 to 440Hz.
