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.
  • Increased power ( 3x compared to standard EI30 transformer)
  • Efficiency typically 70% compared to 40% for typical transformer
  • Wide input voltage range
  • Self-extinguishing UL 94 VO plastic and resin
  • EN 60950, EN60335 & EN61558-2-17 approved
  • Meet EMC standards EN 55014-1, EN55022 class B
  • Now available with FULL APPROVALS – VDE, CE, ENEC, UL, ISO
