RPM7020-20-S

Overview

The Astrodyne TDI RPM7020-20-S is a single-phase EMI power line filter designed for chassis mounting. It features a dual-stage architecture to provide effective noise suppression in AC power circuits. The unit supports a rated current of 20 A and operates at voltages up to 300 V. It is compatible with frequencies ranging from 50 Hz to 400 Hz, making it suitable for both standard 50/60 Hz mains and specialized 400 Hz aerospace applications. The filter utilizes threaded posts (M5) for secure installation.

Feature Summary

• Dual-stage design for enhanced electromagnetic interference suppression
• Compact form factor optimized for professional chassis mounting
• Capable of handling high-frequency operations up to 400 Hz

Applications

• Aerospace avionics power systems
• Military electronic equipment
• Industrial control panels requiring EMI filtering

Procurement Notes

Verify the specific voltage and frequency requirements against the datasheet before procurement. Confirm that the M5 threaded post mounting style matches the chassis design. Ensure the 20 A continuous current rating exceeds the maximum load of the protected circuit to prevent thermal failure.

Selection Notes

Select this model when a single-phase solution is required for environments operating at 50/60 Hz or 400 Hz. The 20 A rating distinguishes it from lower-current variants in the RPM7020 series. Consider the chassis mount configuration if panel space is limited compared to rack-mount alternatives.

Part Context

This component belongs to the RPM7020 series of compact AC filters from Astrodyne TDI. The series offers various current ratings, with the -20-S suffix indicating the 20 Ampere capacity. These filters are engineered for MIL/COTS applications where size and performance are critical constraints.

Replacement Considerations

Check for other RPM7020 variants with different current ratings if the load profile changes. Verify compatibility with alternative mounting styles if chassis modifications are necessary.
