FEATURES

  • Power Rating: 1 kVA (1000 VA / roughly 4.1 to 4.5 Amps depending on the input voltage rating like 220V/240V).
  • Function: Acts as a variable AC voltage regulator using a toroidal copper coil and a carbon brush wiper.
  • Output: Delivers a smooth, stepless, and distortion-free AC waveform adjustment from 0V up to the maximum input voltage (and sometimes an over-voltage boost position).
  • Non-Isolated: Like standard autotransformers, it does not provide galvanic isolation from the mains power supply.
