Series C-44: VDE PC Mount Transformers
4000-volt RMS Hipot, available in a variety of sizes. Insulation Class 130C. Available with
either 115V or dual 115/230V primary. MCi's split bobbin and non-concentric winding provide better
insulation and high isolation, thus eliminating the need for electro-static 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.

Part Number Designation:
- Locate the column, in the table above, for the required voltage.
- In the voltage column, locate the required current reading.
- Moving left from the current reading, find the number indicating required
primary - dual 115V/230V.
- Derive part number by combining digits indentifying required primary and digits at the top
of column giving required voltage.
