Product overview

Description

The STEVAL-ILD003V1 demonstration board is designed to propose a low-cost analog dimmer topology using a sensitive SCR TS820-600FP. The dimmer can drive typical low-consumption lamps, particularly CFL and LED dimmable lamps.

Through-hole technology is used for the most important components such as LC filter, gate resistor, turn-on delay capacitor, etc., in order to allow board modification, if needed.

The STEVAL-ILD003V1 eliminates flickering thanks to its continuous current applied through the sensitive SCR gate. This dimmer could easily replace a standard low-cost analog Triac light dimmer using a Diac-controlled circuit.

  • All features

    • Operation for 2-wire wall dimmer
    • Leading-edge control (compatible with all lamps commonly found on the market)
    • Operation on 230 V line rms voltage (198 to 264 V) and 50 Hz or 60 Hz line frequency
    • Dimmable power range with halogen, CFL and LED lamps (without heatsinks mounted on SCRs1):
      • 3 to 350 W for 230 V rms line
    • Maximum operating ambient temperature: 60 °C
    • Power efficiency @ 350 W / 230 V > 99%
    • Standby losses @ 230 V < 0.5 W (could be reduced to 0 if potentiometer features a mechanical switch to open the circuit at minimum setting)
    • RoHS compliant
    • Compliance with EMC standards
      • IEC 61000-4-4: criteria A for more than 2 kV
      • Compliant with EN55015 with 350 W / 230 V halogen lamp
