A step-down transformer is a device, its secondary voltage is less than the primary voltage. The step down transformer is designed to reduce the voltage from the primary winding to the secondary winding. This kind of transformer "steps down" the voltage applied to it. There are many uses for step-down transformer .The larger devices are used in electric power systems and the smaller units in electronic devices. Industrial and residential power transformers that operate at the line frequency (60 Hz in the U.S., and 50Hz in much parts of Europe and South America),
There are two types of step down transformers: - with AVR and without AVR |
