4,000-Volt RMS Hipot, in a variety of sizes. Maximum operating temperature 155°C. Available with either 115V or dual 115/230V primary. MCI's split bobbin and non-concentric winding provide better insulation and high signal isolation, thus eliminating the need for electrostatic shielding. These transformers are designed to pass VDE's strict creepage distance requirements. Adaptations of standard transformers are also available. Dots on schematics shown below indicate like polarity.
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-dual 115/230V.
  4. Derive part number by combining digits identifying required primary and digits at top of column giving required voltage.
