RPM7050-20-S

Overview

The Astrodyne TDI RPM7050-20-S is a single-phase EMI power line filter designed for MIL/COTS applications. It features a compact 1U height form factor and utilizes a dual-stage filtering architecture to suppress electromagnetic interference. The unit supports an operating frequency range of 50 Hz, 60 Hz, and 400 Hz. Rated for a continuous current of 20 A at voltages up to 300 V, it incorporates threaded post (M5) stud terminations for secure chassis mounting. The component exhibits a leakage current of 3.5 mA, ensuring compliance with safety standards in sensitive environments.

Feature Summary

• Dual-stage filtering architecture for enhanced noise suppression
• Compact 1U height design suitable for space-constrained installations
• Threaded post (M5) stud termination for robust mechanical connection
• Supports multiple operating frequencies including 400 Hz

Applications

• Military electronic systems requiring MIL-spec compliance
• Commercial Off-The-Shelf (COTS) equipment integration
• Avionics power distribution units
• Chassis-mounted industrial control panels

Procurement Notes

Verify the specific suffix 'S' confirms the threaded post (M5) termination style required for your chassis mounting holes. Confirm that the 20 A current rating aligns with your system's peak load requirements. Ensure the 300 V maximum voltage rating exceeds your operational DC or AC line voltage. Check that the 3.5 mA leakage current meets your specific safety isolation standards. Validate compatibility with 50/60/400 Hz input sources before finalizing procurement.

Selection Notes

Select this model when a single-phase, dual-stage filter is required for MIL/COTS applications. The 1U height makes it ideal for rack or panel mounts where vertical space is limited. Choose the 'S' variant specifically if M5 threaded post connections are preferred over screw terminals. Ensure the 20 A rating covers your maximum continuous current draw. Verify that the 300 V rating is sufficient for your system's voltage levels.

Part Context

This component belongs to the Astrodyne TDI RPM7050 series, which offers various current ratings and termination options within a standardized 1U height footprint. The series is engineered for high-performance EMI suppression in demanding environments. The RPM7050-20-S specifically denotes the 20 Ampere current rating and stud termination configuration within this family of single-phase filters.

Replacement Considerations

Consult official Astrodyne TDI documentation for direct cross-references. Ensure any substitute maintains the 1U height, 20 A rating, and M5 stud termination. Verify equivalent leakage current and voltage ratings. Generic replacements may not meet MIL/COTS specifications.
