Overview
The SE45 is a single-phase EMC/EMI power line filter module manufactured by Astrodyne TDI. It features a two-stage filtering architecture designed to suppress electromagnetic interference in AC power circuits. The unit supports a maximum current rating of 45 amperes at 250VAC and operates at standard 50/60Hz frequencies. Constructed with threaded posts (10-32) for secure mounting, it serves as a critical component for protecting sensitive electronic equipment from conducted noise in industrial and commercial power distribution systems.
Feature Summary
- Two-stage EMI/EMC filtering architecture for enhanced noise suppression
- High current capacity rated for 45 amperes at 250VAC
- Threaded post mounting interface for robust mechanical installation
Applications
- Industrial machinery power input protection
- Commercial building electrical distribution systems
- Sensitive medical equipment power conditioning
Procurement Notes
Verify the specific suffix designation (e.g., SE45 F) against official Astrodyne TDI documentation to confirm exact terminal configuration and current ratings. Ensure the selected variant matches the required voltage and frequency specifications for the target application. Cross-reference datasheets for precise physical dimensions and mounting hole patterns prior to integration.
Selection Notes
Select this filter based on the system's maximum operating current not exceeding 45A and the voltage requirements aligning with 250VAC standards. Evaluate the need for two-stage attenuation capabilities versus single-stage alternatives. Confirm that the threaded post mounting style is compatible with the available chassis or panel space constraints in the design.
Part Context
The SE45 belongs to Astrodyne TDI’s dedicated power line filter series, engineered for medium to high-power applications. It complements their broader portfolio of EMI solutions, including shielded enclosure filters and switch-mode power supply filters. This series focuses on providing reliable conducted emission reduction for AC mains inputs in demanding environments.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided reference data. Verify compatibility with existing mounting hardware and circuit parameters before considering alternative models from other manufacturers.
