Digital wall dimmer for halogen and low-consumption lamps
  • active Active

The STEVAL-ILD004V1 evaluation board is designed to propose an innovative and low cost power topology for a light wall dimmer using two sensitive TS820-600FP SCRs and a single STGF10NC60KD IGBT to dim the following lamp types: 100 - 240 V halogen lamps, SELV halogen lamps through magnetic or electronic transformers, and new CFL and LED dimmable lamps.

Control of the board is achieved with the STM8S103F2 microcontroller.
