Three Phase 300 series

Variable Voltage Transformer (Variac Slidac) , Three 3 Phase 220/240V input, 7.62 KVA Max 20A, YH-320(S)

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.
