The Control Transformers transform one level of voltage and current into another. A step up transformer raises voltage and lowers current, usually to make long power lines more efficient, and a step down transformer raises current and lowers voltage, usually to make it safe for homes and appliances. The transformer is an isolation transformer designed to provide a high degree of secondary voltage stability (regulation) during a short period overload condition. The Control Transformers are offered for use in various industrial applications.
