To determine part number for specific transformer to be ordered:

  1. Locate the column, in the table, for the required voltage.
  2. In the voltage column, locate the required current rating.
  3. Moving left from the current rating, find the number indicating required primary-single 115V primary or dual 115/230V.
  4. Derive part number by combining digits identifying required primary and digits at top of column giving required voltage.
