• Transformers and Power Conditioning Equipment

In the constant voltage transformer (CVT) or ferro-resonant stabiliser, the AC mains powers the input winding, which is widely separated physically from the isolated output winding. The input winding normally runs at very moderate flux linkage levels. The output winding exhibits an intrinsic energy storage characteristic and this energy storage operates in conjunction with the mains capacitor to produce self generated AC flux field which is indirectly excited from the input windings. Highlights include: instantaneous voltage regulation; no transient and spikes; and sine wave output – a perfect answer and remedy for every electronic equipments voltage problems.
