IF-18-30

Power Transformers Overview

The IF-18-30 is a split bobbin power transformer manufactured by Signal Transformer. It features dual primaries rated for 115V and 230V input, supporting 50 Hz and 60 Hz operating frequencies. The unit provides two secondary outputs: an 18V center-tapped winding delivering 600 mA and a 15V winding delivering 1.20 A. It incorporates a Class B insulation system and offers a dielectric strength of 4000 Vrms. Approvals include UL, CSA, and VDE standards.

Power Transformers Feature Summary

• Dual primary configuration supports both 115V and 230V line voltages
• Split bobbin construction facilitates efficient winding assembly
• High dielectric strength ensures robust electrical isolation between circuits

Power Transformers Applications

• Industrial automation control systems
• Servo drive power supplies
• General purpose AC to AC power conversion

Power Transformers Procurement Notes

Verify the specific manufacturing date code and lot number upon receipt to ensure compliance with current RoHS directives and material safety data sheets. Confirm that the physical dimensions and pinout configuration match the target PCB footprint requirements before final integration into the design.

Power Transformers Selection Notes

Select this component when a compact solution with dual voltage inputs and multiple isolated secondary outputs is required. The split bobbin design aids in thermal management and manufacturing efficiency. Ensure the load currents do not exceed the specified 600 mA and 1.20 A limits for the respective windings to maintain performance and longevity.

Power Transformers Part Context

This transformer belongs to the standard power transformer lineup from Signal Transformer, designed for reliable operation in industrial environments. The IF series utilizes unique insulating techniques to enhance durability. It serves as a critical interface component for stepping down or isolating mains voltage for sensitive electronic loads.

Power Transformers Replacement Considerations

Direct cross-referencing requires matching the 18VCT @ 600mA and 15V @ 1.20A specifications along with the 4000Vrms isolation rating. Verify that any substitute part maintains the same UL, CSA, and VDE approvals and fits the mechanical constraints of the existing assembly.
