Three Phase Isolation Power Transformers

Coilmag’s Control Transformers are Isolation transformers designed to provide a high degree of secondary voltage stability (regulation) during a brief period of overload condition (also referred to as “inrush current”). These units are also known as Machine Tool Transformers, Industrial Control Transformers or Control Power Transformers
