3F45

Overview

The Astrodyne TDI 3F45 is a three-phase delta EMC/EMI line filter designed for industrial applications. It features a two-stage filtering architecture to suppress electromagnetic interference across power lines. The unit supports a rated current of 45 A and operates at a voltage rating of 250 V AC. It functions within standard frequencies of 50 Hz and 60 Hz. The device utilizes quick connect terminals for electrical termination and is constructed for chassis mounting. This configuration ensures effective noise reduction while maintaining high current capacity in demanding power environments.

Feature Summary

• Two-stage filtering architecture for enhanced EMI suppression
• Quick connect terminal interface for rapid installation
• Chassis mount design for secure physical integration

Applications

• Industrial power conditioning systems
• Three-phase equipment requiring EMI protection
• Delta configuration power distribution networks

Procurement Notes

Verify the specific datasheet version for the 3F45 model to confirm exact terminal dimensions and mounting hole patterns before integration. Ensure the application environment does not exceed the 250 V AC rating or 45 A continuous current limit. Confirm that the quick connect terminals match the available connector types in the system design to avoid compatibility issues during assembly.

Selection Notes

Select this component when a three-phase delta topology is required for EMI mitigation. The 45 A rating suits moderate to high-power industrial loads. Verify that the two-stage performance meets the specific emission standards of the target market. Consider the chassis mount form factor if panel space allows, as PCB mount alternatives may offer different footprint constraints.
