1 For receive channel, to make a 1:2 ratio from a 1CT:1, use only one-half of the primary (1CT) winding.
NOTE: For extended temperature range transformers, OCL (Open Circuit Inductance for the primary winding) is specified at both -40°C and +25°C.
At -40°C, OCL is 600 µH minimum. All other parameters are specified at +25°C.
