3E80 F

Overview

The Astrodyne TDI 3E80 F is a three-phase switch mode EMI filter designed for high-current industrial applications. It features an 80 A current rating and operates at voltage ratings up to 440 VAC or 250 VAC depending on configuration. The unit utilizes a two-stage filtering architecture with threaded post termination (5/16-18) for secure chassis mounting. Physical dimensions include a length of 10 inches and a height of 4.75 inches, ensuring compatibility with standard industrial enclosures.

Feature Summary

• Two-stage electromagnetic interference suppression architecture
• High-capacity 80 A current handling capability
• Robust bolt-in termination using threaded posts

Applications

• Three-phase power conditioning systems
• Industrial machinery requiring EMI mitigation
• Switch mode power supply input stages

Procurement Notes

Verify the specific voltage rating (250 VAC vs 440 VAC) required for your application against the datasheet specifications. Confirm that the chassis mounting holes align with the physical dimensions provided. Ensure the termination style matches your wiring infrastructure before ordering.

Selection Notes

Select this component when high current capacity is critical for three-phase systems. The threaded post termination offers superior mechanical stability compared to quick-connect options. Evaluate the two-stage design benefits for stringent noise reduction requirements in sensitive electronic environments.

Part Context

This model belongs to the 3E series of power line filters from Astrodyne TDI. The series focuses on robust construction for demanding industrial environments. The 3E80 F variant specifically addresses high-amperage needs where standard filters may fail under load.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Verify pinout and dimensional compatibility if considering alternative manufacturers. Consult official engineering support for cross-reference validation.
