MCI 4-24 Series

CE - UL Class 2 PC Mount

The MCI Transformer Corporation 4-24 Series UL Class 2, PC mount transformers are 4,000-Volt RMS Hipot, available in a variety of sizes. Maximum operating temperature 155°C. Available with 115/230V primary. Our 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 CE’s strict creepage distance requirements. Adaptations of standard transformers are also available. Dots on schematics shown below indicate like polarity.

NOW AVAILABLE WITH LEAD WIRES – SINGLE 115V OR 230V PRIMARY OR DUAL 115/230 PRIMARIES
