IF-2-40

Power Transformers Overview

The IF-2-40 is a semi-toroidal power transformer from the IF series, designed for through-hole mounting. It features dual primary windings rated for 115V and 230V operation. The secondary configuration provides 40VCT at 50mA in series or 20V at 100mA in parallel. This component utilizes Class B insulation and offers a 4000Vrms hipot dielectric strength.

Power Transformers Feature Summary

• Semi-toroidal core construction
• Dual primary voltage capability
• Flexible secondary output configuration
• High dielectric strength isolation

Power Transformers Applications

• General purpose AC power supply circuits
• Equipment requiring isolated low-voltage DC conversion
• Industrial control systems with standard mains input

Power Transformers Procurement Notes

Verify the specific manufacturer designation, as components may be sourced from Signal Transformer or Bel Signal Transformer. Confirm that the received unit matches the IF-2-40 part number and physical dimensions. Ensure the insulation class and voltage ratings align with your system requirements before integration.

Power Transformers Selection Notes

Select this model when a compact semi-toroidal form factor is required for space-constrained designs. Choose based on the need for dual primary flexibility to support both 115V and 230V mains inputs without rewiring. Consider the specific current and voltage outputs needed for the secondary side.

Power Transformers Part Context

This component belongs to the IF series of standard power transformers manufactured by Signal Transformer. The series includes various models with different voltage and current ratings, all sharing similar semi-toroidal construction and mounting characteristics for consistent performance across applications.

Power Transformers Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that any replacement maintains the same electrical specifications, including 40VCT/20V secondary outputs and dual primary compatibility, to ensure circuit functionality.
