Single or double phase control transformers are commonly used in machine control panels, automation panels etc  either as security step up or step down transformer, in some cases step-up and step down transformers can be produces as auto transformer for reducing the price.
        • Nominal Power
        • Isolation type or auto type
        • Input-output voltage and current values according to duty factor
        • Galvanic isolation
        • Input - Output voltage steps
        • Input-output connection materials
        • Isolation class
        • Mounting type ( horizontal - vertical ) ... etc
GUVEN-IS determines these technical specifications by communicating directly to the customer before designing process in order to avoid any problem.  When every detail is clear a sample transformer is produced and tested by GUVEN-IS and submitted to the customer for the final approving before the ordering.
