Telemetry & LED LIGHT driver, wireless controller. (control gear) The board has an embedded AC/DC converter that keeps its total power consumption far less than the max 0.5W requirement of the Ecodesign Directive 2005/32/EC, while telemetry (control gear) is kept active and during the stand-by mode of the LED driver. The Ecodesign Directive 2005/32/EC of the European Parliament and of the Council has the following main requirements: •Max 1 W power for passive standby and off-mode starting in 2010 •Max 0.5 W from September 2016

Experiência

Chief electronic Engineer

ASPiSYS Ltd
mar. 1997 - Atual
I have worked for ASPiSYS ltd since the birth of the company, being responsible for the designing of all the projects hardware part. During all those years, I have done many designs from scratch, covering almost all spectrum of electronics, ie. RF systems (HF, VHF, UHF, SHF up to 5 GHz), RF Power amplifiers (up to 5 kW), digital systems and embedded systems (SMB for industrial electronics), access control systems, marine electronics (BNWAS), telecommunication systems (GSM/GPRS units), SMPS modules, Power inverters, and too many other that it will take too much space to write them all here.

Chief electronic engineer

FLASH SA
nov. 2002 - mar. 2007 (4 anos, 4 meses)
During the November of 2002 Intracom SA sold the Radio & Television support department to FLASH SA, owner of the FLASH 961 radio station and at that time also for the MAGIC TV station. As a chief engineer of the related department I was directly hired by FLASH SA to keep supporting the stations they owned.

Chief Electronic Engineer

Intracom SA - Radio & TV Support division
jan. 1995 - nov. 2002 (7 anos, 10 meses)
I was the Chief Electronic Engineer for the Radio & television support department. Main job was to provide full technical support (both for studio & RF equipment) for FLASH 961, Athens Radio station, that has been one of the most well known stations at Greece during the 1990 -2008 period
