Drive Type Transformer


Drive Isolation Transformers are used to power Adjustable Speed Drive systems that use Silicone Controlled Rectifiers (SCR). When the SCR is activated, a burst of current flows to the transformers. The Drive Isolation Transformers withstands those surges and supports the harmonics generated by the drive.
