Progettazione e produzione di alimentatori e trasformatori: Comatec   


BXS-LED serie


  Input voltage:  230 Vac  
  Nominal current:  250 mA  

The BXS-LED drivers are produced at our Comatec production unit in Perugia (Italy). They use a flyback converter with galvanic isolation and constant current output. They have been conceived to drive power white light LEDs connected in series to a maximum 6 LEDs. They are available in two versions, according to their power ranges. In this way it is possible to use LEDs made by different producers, but it is not necessary to add any externally polarized components. They have been conceived for use in trunking boxes or in other LED lighting devices.
