Variable Voltage Transformer (Variac Slidac) , Single Phase 110/220V input, 1.1 KVA Max 10A, YH-110
A Variable Autotransformer, also known as a Variac or Slidac, is an electrical device used to smoothly adjust AC voltage output from 0 volts up to the input voltage or higher. Unlike traditional transformers, it uses a single winding and a sliding contact (carbon brush) to provide continuous voltage variation without steps or interruptions.
