AUTM
The autotransformer is made with a single winding from which the various output voltages are taken. This type of transformer does not feature any form of galvanic separation from the primary circuit. The size-power ratio of an autotransformer is a function of the maximum (Vmax) and minimum (Vmin) input/output voltage in accordance with the following formula:
Core power handling= (Vmax – Vmin) / Vmax X Rated output power (VA) Use the result to find the autotransformer size needed in the following table. AUTM series units for general use are manufactured on demand.
