Step Down Transformer
In StockA Step Down Transformer is an electrical device designed to reduce high input voltage to a lower, safer, and usable output voltage level without altering the frequency. It operates on the principle of electromagnetic induction, where the primary winding receives high voltage, and the secondary winding delivers proportionally lower voltage according to the turn ratio.
Step down transformers are widely used in industrial plants, commercial setups, and residential applications to power machines, lighting systems, and sensitive electronic devices that require specific voltage levels. Built with high-grade copper or aluminum windings and laminated core materials, they ensure high efficiency, minimal energy loss, and long operational life.
