We are looking for somebody who will able to find EMC problems and improve our design.
Specification of our design:
power supply: nominal 12VAC/50Hz-10kHz
- toroidal transformer
- pulse electronic transformer for halogen (0-50W)
output current: 500mA
output voltage: about 11VDC (High-Power LED x 3 in serial connection)
operating temperature: from 0*C upto +85*C
applicable EMC standards:
EN55022 (RF emission)
EN55015 (conducted emission) -> tested whole system: LED lamp + toroidal transformer 230VAC/12VAC
EN61000 (burst, surge, transients, magnetic filed, etc)
We have problem with RF- and conducted emissions (above the limits). EN61000 we did not test yet.
- corrected documentation of our power supply (under Altium Designer)
- EMC test report for corrected prototype power supply PCBs
Final full payment only.
