TRANSFORMER VCT DEFINED
VCT stands for Voltage Center Tapped. The center tap provides a third wire connected to the electrical middle of the secondary winding wires. The total rated voltage is available between the two outside secondary wires.
One half (1/2) of the rated voltage is available from either end of the secondary winding wires to the center tap wire.Â
For example, The TRF-170 has 18V on each side.
