3E30 F

Overview

The Astrodyne TDI 3E30 F is a three-phase (Y) switch-mode EMI filter designed for industrial power line applications. It features a dual-stage filtering architecture to suppress electromagnetic interference across both differential and common modes. The unit supports a rated current of 30A and operates with an input voltage up to 250V at 50/60Hz frequencies. Mechanical mounting utilizes a flange configuration with threaded posts, specifically 10-32 threads, ensuring secure installation in high-vibration environments. The component weighs approximately 6.5 lbs and measures 102mm in height, providing robust noise attenuation for sensitive electronic equipment connected to three-phase power systems.

Feature Summary

• Dual-stage line filter design for enhanced noise suppression
• Three-phase Y configuration compatible with standard industrial power distribution
• Flange mounting with threaded posts for secure mechanical attachment

Applications

• Industrial machinery power conditioning
• Medical equipment power supply protection
• Telecommunications infrastructure filtering

Procurement Notes

Verify the specific datasheet version from Astrodyne TDI or authorized distributors to confirm exact electrical tolerances and environmental ratings. Ensure the mounting hole pattern matches the 10-32 threaded post specification. Check for any required ordering suffixes that may indicate specific lead times or packaging variations. Confirm compliance with relevant EMC standards for the target region before finalizing procurement orders.

Selection Notes

Select this model when a three-phase solution is required for currents up to 30A. The dual-stage design offers superior attenuation compared to single-stage alternatives. Consider the physical dimensions and weight for enclosure space planning. Verify that the 250V input rating aligns with the system's nominal voltage levels to ensure safe operation under all expected load conditions.

Part Context

This component belongs to the 3E Series of switch-mode EMI filters manufactured by Astrodyne TDI. The series provides various current ratings ranging from 15A to 200A. The 3E30 F specifically addresses the 30A requirement within this lineup. It is part of Filter Concepts' portfolio, focusing on reliable noise reduction for demanding power electronics applications worldwide.

Replacement Considerations

Direct substitutes must match the three-phase Y configuration, 30A rating, and dual-stage topology. Verify compatibility with 10-32 threaded post mounting. Cross-reference with other Astrodyne TDI 3E series models if current requirements differ slightly, but ensure electrical parameters remain identical to maintain system performance.
