Product Information

Auto Transformer

We specialize in offering a wide range of Auto Transformer, which is also known as auto former. This Auto Transformer is an electrical transformer with only one winding that has at least three electrical connection points called taps. Our range of Autotransformer is fabricated using quality material to ensure high efficiency and trouble free service life.

Application usages:

Used for machines in which voltage ranges from 480 V supplies to a 600 V supply.
Used for providing conversions between the two common domestic mains voltage bands that range from 100-130 and 200-250
Used for 'Super Grid' networks that range from the UK 400kV to 275kV
Used for long rural power distribution lines in which the variable ratio of the auto transformer balances voltage drop along the line.
Tapped auto transformer is used in a speaker to regulate constant-voltage audio distribution system. In other words, it is used for impedance matching that varies from a low-impedance microphone to a high-impedance amplifier input

Features
Performs the same function as an isolation transformer of same KVA and voltage rating without the isolation feature

Ventilated openings in the enclosure are coordinated with the cooling ducts in the coils to ensure proper natural circulation of air for long life and minimum losses.
General purpose indoor ventilated steel enclosure suitable for dry locations. After fabrication, the enclosure is finished in ASA61 grey powder paint suitable for most industrial and commercial installations.

Most units have lifting lugs, conduit knockouts and removable front and back covers for easy access to terminals.
