Step-Down transformer

Overview

When voltage is applied to one coil (frequently called the Primary or input) it magnetizes the iron core, which induces a voltage in the other coil, (frequently called the secondary or output).The turns ratio of the two sets of windings determines the amount of voltage transformation.
A Step-down transformer is one whose secondary voltage is less than its primary voltage. The step down transformer is designed to reduce the voltage from the primary winding to the secondary winding.

Features

● There are air flows between coils’s layer to layer and between coil to core, resulting fast heat dissipation, and low temperature rise.
● High grade iron core and winding can be wire or foil
● Small volume, light weight and good workmanship.
● After vacuum pressure impregnating, the whole transformers and reactors are moisture proof and mildew proof.
● Insulation class H or C.
● Lower audio noise.
● Nomex based insulation system for foil winding transformers and reactors.
