Datasheet

## **47000 SERIES  -   ELECTRONIC TRANSFORMERS** 

## **MYRRA encapsulated electronic transformers are Switched Mode Power Supplies based on Flyback topology.** 

## **MAIN FEATURES** 

- **Wide input voltage range** 

**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 applications of power up to than 5W 

   - Alternative to DC/DC converters for application in D.C.current (Telecom supplies, electric substations etc.) 

   - **Increased power.  3 x compared to standard EI30 transformer** 

   - **Better energetic efficiency: 70% typical compared to 40% for the conventional supply** 

   - **Very low Standby Power consumption: meets requirements of Energy Star or EC Code of Conduct** 

   - **Same footprint as EI30 transformer : Upgrade your application without redesign of PCB** 

- Industrial, domestic and consumer electronics applications 

- Standby devices and others DC or AC auxiliary supplies 

## **SAFETY STANDARDS** 

Meets all  requirements of: 

- EN 60950 

With the same footprint as a EI30 transformer, they will replace: 

- 50 Hz Transformer 

- Fuse 

   - EN 60335 

   - EN 61558-2-17 

   - Uses UL listed components 

   - `o` Uses UL 94-V0 plastic and resin 

- Bridge Rectifier 

- Filtering Capacitor 

Regulated types will also replace linear regulator and heatsink 

## **EMC STANDARDS** 

Conducted and radiated emissions conform to 

- EN 55014-1 

- `o` EN 55022 class B 

- Immunity conform to 

- EN 55014-2 

- EN 61000-4-x

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
