Constant Voltage Transformer

Product Details:

The portion of the magnetic core over which the secondary winding is wound is saturated, while the portion over which the primary is wound is not saturated. This capacitor also makes the current in the secondary winding to increase which helps in the saturation of the secondary flux. Since the secondary ac flux is restricted to a saturated value for a large range of the input voltage (170-270 V),  a constant voltage is available across the secondary winding 230V.
