Electronic Transformers 47000

Electronic transformers
47000 Series


MYRRA encapsulated electronic transformers are Switched Mode Suppline based on Flyback topology.

They constitute an interesting alternative to the traditional supply
in the most common applications of power lower than 5W.

ENERGY SAVING due to high efficiency and low standby power.

The applications for the Electronic serie are:

  •   Alternative to the linear transformers in all AC/DC aplications up to than 5W
  •   Alternative to DC/DC converters for application in D.C. current (Telecom supplies, electric substations etc.)
  •   Industrial, domestic and consumer electronics applications
  •   Standby devices and others DC or AC auxiliary supplies

With the same footprint as a El30 transformer, they will replace:

  •  50Hz Transformer
  •  Fuse
  •  Bridge Rectifier
  •  Filtering Capacitoк

Regulated types will also replace linear regulator and heatsink.


  • wide input voltage range
  • Increased power 3x compared to standard El30 transformer
  • Better energetic efficiency: 70% typical compared to 40% for the conventional supply
  • Very low Standby Power consumption: meets requirements of Energy or EC Code of Conduct
  • Same footprint as El30 transformer: Upgrade your application without redesign of PCB

Meets all requirements of:

  • EN 60950
  • EN 60335
  • EN 61558-2-17
  • Uses UL listed components
  • Uses UL 94-VO plastic and resin

Conducted and radiated emissions conform to

  • EN 55014-1
  • EN 55022 class B

Immunity conform to:

  • EN 55014-2
  • EN 61000-4-x
