Product Description
What is a Variable Transformer?
A variable transformer, also known as a Variac, is a step-less, adjustable voltage transformer that provides smooth and precise voltage control. Unlike traditional transformers, a variable transformer allows continuous voltage variation from 0V to 117% of the input voltage, making it ideal for applications requiring fine voltage adjustments without distortion.
How Does a Variable Transformer Work?
A variable transformer consists of a toroidal copper winding on a laminated silicon steel core. A carbon brush moves along a commutator track, tapping voltage at different points, allowing users to adjust the output voltage smoothly. This ensures a stable power supply without waveform distortion, making variable transformers highly reliable for sensitive applications.
