2. Company Mission To develop and commercialize its proprietary technology and products, which are based on a patentable electronic measurement component

3. Team n The development group consists of highly experienced engineers in the following fields of activity: u Hardware Engineering u Mechanical Engineering u Test Engineering

4. Technology A unique measurement device based on new technology that has no analogs in the entire world.

5. Distinguishing features n The EPMC permits SMT design even for big currents. n No additional soldering process is required, only reflow. n The EPMC permits to reduce the assembled card height. n Reduced heights of the cards permit to insert more cards in the same rack. n The EPMC is more compact, saving Printed Circuit Board area. n It is easy to customize the component if the customer has special needs.

6. Distinguishing features (cont’d) u By increasing the primary current the dimensions of the sensor are not increasing significantly. u Completely linear without saturation. u Completely symmetrical without false operation. u Highest accuracy (the target is ±0.05%). u SMT for all ranges of current.

7. Distinguishing features (cont’d) u New technology, only one technological process is used. u Small dimensions save PCB area. u No further amplification and signal processing is needed. u Unmatched parameters consistency. u Minimum electromagnetic interference. u Wide operating temperature range.

8. Current Technology Disadvantages of existing technologies: u By increasing the primary current the diameter of the primary wire and the dimensions of the sensor are increasing significantly. u A magnetic material with saturation gives non linearity of measurement and saturation at big currents. u A non symmetrical position of wires in RC Devices causes false operation. u Very low accuracy (±10% in standard devices, 0,2% in calibration devices). u Through hole devices. SMT devices only for low currents.

9. Current Technology (cont’d) Disadvantages of existing technologies : u Through hole devices – old technology, two technological processes must be used. u Through hole devices with a magnetic material have large dimensions. u Output voltage is measured in 5-10 mV (very low). Output voltage needs amplification and signal processing. u No consistency in parameters. u Maximum electromagnetic interference. u Restricted operating temperature range.

10. The Need The existing technologies do not provide sufficient accuracy Also, they do not provide signal processing and need additional components Therefore, there is a need for a new technology that will provide the needed parameters. The proposed device aim to overcome the disadvantages of the existing devices.

13. Patent Status. n a. A patent search was performed: no such device is patented. The EPMC is patentable. n b. From the point of view of somebody's rights violation: we do not violate any rights of anybody.

14. Size of the Market n There are more than 8800 manufacturers of the old technologies current transformers in the entire world. n The current transformers market is more than 8 billions $US. n It is very difficult to evaluate the market for other EPMC applications because the numbers are huge. n The total world market is measured in Billions of $US.

15. Alliance with Strategic Partner A.L.F. Enterprise is looking for a future development and marketing alliance with a partner that produces technical and mechanical electronic components of the highest quality.
