General Description

: Since the operating currents of some electronic transformers are below the holding current of most triacs, a typical triac- OVC - Overcurrent Sense Input (Pin 6) based (leading-edge) dimmer may not operate properly when The voltage at this input is sampled every half-cycle in a driving an electronic transformer-coupled low-voltage halogen four-cycle period.

If the voltage reaches the OVC threshold lamp.

The filtering components in the electronic transformer four times, then the Gate Output is turned Off shutting down which preve

Key Features

  • Pushbutton or touch control of high-voltage lamps and all electronic transformer-coupled low-voltage halogen lamps.
  • Controls Fluorescents and CFLs via dimming ballasts.
  • Reverse-phase technology eliminates RFI generation.
  • “FO" versions power up Full On after.
