Autotransformers

An autotransformer is a compact, cost-effective electrical transformer that uses a single shared winding to step voltage up or down. Unlike standard transformers with two separate coils, the autotransformer uses a common connection point, making it significantly lighter and more efficient for specific voltage adjustments.

Why Choose an Autotransformer?

• Space-Saving: Smaller footprint and less weight due to the single-coil design.
• Cost-Effective: Uses less copper and core material than isolation transformers.
• Better Regulation: Offers lower leakage reactance and higher efficiency.
• Versatile: Perfect for boosting or bucking voltage in industrial and laboratory settings.

Ideal For:

• Adjusting supply voltage for industrial machinery.
• Compensating for voltage drops in long power lines.
• Variable AC power supplies (Variances) for testing.
