47000 SERIES - ELECTRONIC TRANSFORMERS
MYRRA encapsulated electronic transformers are
Switched Mode Power Supplies 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:
o Alternative to the linear transformers in all
AC/DC applications of power up to than 5W
o Alternative to DC/DC converters for application
in D.C.current (Telecom supplies, electric
substations etc.)
o Industrial, domestic and consumer electronics
applications
o Standby devices and others DC or AC auxiliary
supplies
With the same footprint as a EI30 transformer, they
will replace:
- 50 Hz Transformer
- Fuse
- Bridge Rectifier
- Filtering Capacitor
Regulated types will also replace linear regulator and
heatsink
MAIN FEATURES
o Wide input voltage range
o Increased power. 3 x compared to standard
EI30 transformer
o Better energetic efficiency: 70% typical
compared to 40% for the conventional
supply
o Very low Standby Power consumption:
meets requirements of Energy Star or EC
Code of Conduct
o Same footprint as EI30 transformer :
Upgrade your application without redesign
of PCB
SAFETY STANDARDS
Meets all requirements of:
o EN 60950
o EN 60335
o EN 61558-2-17
o Uses UL listed components
o Uses UL 94-V0 plastic and resin
EMC STANDARDS
Conducted and radiated emissions conform to
o EN 55014-1
o EN 55022 class B
Immunity conform to
o EN 55014-2
o EN 61000-4-x
