3H45

Overview

The Astrodyne TDI 3H45 is a three-phase (Wye) EMC/EMI power line filter module designed for industrial applications. It features a two-stage filtering architecture to ensure effective noise suppression across the power spectrum. The unit is rated for 480 VAC and supports a continuous current of 45 A at 50/60 Hz operating frequencies. Physical installation is facilitated by threaded posts, specifically 10-32 size, allowing for secure chassis mounting. This component integrates high-performance filtering capabilities within a robust modular form factor suitable for demanding electrical environments.

Feature Summary

• Two-stage filtering architecture for enhanced electromagnetic interference suppression
• Three-phase Wye configuration compatible with standard industrial power systems
• Threaded post mounting design for secure mechanical integration

Applications

• Industrial machinery power conditioning
• Electromagnetic compatibility compliance in manufacturing equipment
• Power distribution units requiring noise reduction

Procurement Notes

Verify the specific datasheet version for the 3H45 model to confirm exact dimensional tolerances and terminal specifications before integration. Ensure that the incoming power supply matches the 480 VAC rating and 45 A current capacity. Confirm that the 10-32 threaded post mounting holes align with the enclosure design. Check for any regional compliance certifications required for the target market.

Selection Notes

Select this model when a three-phase solution is required for high-current applications up to 45 A. The two-stage design is appropriate for environments with significant conducted noise. Ensure the Wye configuration matches the system neutral grounding scheme. Consider the physical dimensions and mounting requirements associated with the threaded post interface during system layout planning.

Part Context

This component belongs to the Astrodyne TDI power line filter modules series, which provides EMI/RFI suppression solutions. The 3H45 variant specifically addresses three-phase needs, distinguishing it from single-phase models like the RP series. It serves as a critical interface between the power source and sensitive loads to maintain signal integrity and regulatory compliance.

Replacement Considerations

No direct public substitute part numbers are confirmed for the 3H45 model. Any replacement must match the three-phase Wye configuration, 45 A current rating, 480 VAC voltage rating, and 10-32 threaded post mounting style. Verify that alternative components offer equivalent two-stage filtering performance.
