The MCI 4-06/4-07 Series of chassis mount transformers are 2,500-volt RMS Hipot and are available in a variety of practical sizes. Maximum operating temperature 155°C. Available with either single 115 or dual 115/230V primary (for all but 2.4 VA or size).
MCI Transformer Corporation’s split bobbin and non-concentric winding provide better insulation and high signal isolation, thus eliminating the need for electrostatic shielding. Adaptations of standard transformers are also available. Dots on schematics shown below indicate like polarity.
