RPM8500-70-S

Overview

The RPM8500-70-S is a single-phase, two-stage power line filter from the RP428 series manufactured by Astrodyne TDI. It is rated for 70 A current and 250 VAC voltage at operating frequencies of 50 Hz, 60 Hz, and 400 Hz. The unit features chassis mount installation with stud termination and has a maximum operating temperature of +70°C.

Feature Summary

• Two-stage filtering architecture for enhanced noise attenuation
• Compatible with 50 Hz, 60 Hz, and 400 Hz operational frequencies
• Designed for high-current applications up to 70 A

Applications

• Military electronic systems requiring EMI suppression
• Commercial off-the-shelf (COTS) equipment power conditioning
• Industrial machinery power input stages

Procurement Notes

Verify the specific datasheet version for leakage current and insertion loss values before integration. Confirm that the stud termination size matches the chassis mounting hardware. Ensure the 70 A rating aligns with the system's continuous load requirements and ambient temperature conditions.

Selection Notes

Select this component when dual-stage attenuation is required for single-phase AC lines in environments supporting 400 Hz operation. Compare against the broader RPM8500 series for alternative current ratings if the 70 A specification exceeds or falls short of the design needs.

Part Context

This part belongs to the RPM8500 series, which provides MIL/COTS compliant power line filters. The RP428 series designation indicates specific internal circuit topology optimized for high-performance electromagnetic interference reduction in demanding power supply applications.

Replacement Considerations

Consult official substitution lists for equivalent current ratings within the RPM8500 family. Verify mechanical dimensions and terminal compatibility before replacing with other single-stage or two-stage variants.
