Single phase Autotransformer MC75H-C has common primary-secondary windings which are not insulated from each other, offers no interference or disturbance isolation between primary and secondary circuits. It is an economical solution but is not suitable for sensitive equipment with electronic components and perfectly suitable for simple motor or heater single applications.
