Itacoil’s voltage measurement transformer. Accept voltage values from 100VAC to 275VAC with a typical linearity error of less than ± 0.50%. It has two secondary ones that, depending on how they are connected, allow to obtain a certain output voltage. With a nominal input voltage of 230 VAC, connecting the secondary units in series measures a voltage of 10Veff at the free ends. The load resistance to be used in this case is 10 kohms.
