China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

The dimming ballasts, there are at least two of the iron core of the magnetic circuit on the main magnetic flux path is wound on the primary winding, on the side of the iron core of the magnetic circuit on the regulating winding around the regulating winding and is connected to the control circuit, the control circuitcontrolling the phase of the regulating winding and the induced current, which is characterized by: the edge of the magnetic flux of the magnetic circuit is less than the magnetic flux of the main magnetic flux path. Since the present invention uses the main winding wound on the main magnetic flux path, and regulating winding in the the edge magnetic circuit around the upper edge of the magnetic flux of the magnetic circuit is less than the magnetic flux of the main magnetic flux path such that the inductance of the main magnetic flux path is not saturated, so when in use without and an inductor in series.
