... Caution: As most applications will use the transducer with only one single primary turn (N = 1), much of this datasheet is P written in terms of primary current instead of current linkages. However, the ampere-turns (A-t) unit is used to emphasis that current linkages are intended and applicable. Transducer simplified model ...
