RPM8500-125-S

Overview

The RPM8500-125-S is a MIL COTS Delta EMI power line filter manufactured by Astrodyne TDI. It supports a current rating of 125 A and operates at 480 VAC, 60 Hz. The unit utilizes chassis mount installation with stud termination. As a three-phase solution, it provides electromagnetic interference suppression for demanding industrial or military applications requiring robust power conditioning.

Feature Summary

• Three-phase Delta configuration for balanced load filtering
• MIL COTS compliance for rugged operational environments
• High-current capacity design for heavy-duty machinery

Applications

• Military ground vehicle power systems
• Industrial motor drive protection
• Avionics power distribution units

Procurement Notes

Verify the specific datasheet revision to confirm exact attenuation curves and physical mounting hole dimensions. Ensure the input voltage matches the 480 VAC rating before integration. Confirm that the stud termination type aligns with existing busbar or cable lug specifications in the assembly design.

Selection Notes

Select this model when three-phase noise suppression is required for high-amperage circuits. Compare against single-phase alternatives if system topology differs. Verify thermal management requirements as high-current filters may generate heat under continuous load conditions.

Part Context

This component belongs to the RPM8500 series, which offers various current ratings from 10 A to 150 A. The series is designed for harsh environments, providing reliable EMI filtering across military and commercial sectors. It complements other Astrodyne TDI power entry modules and standalone filters.

Replacement Considerations

Check for direct cross-references within the RPM8500 family for different current ratings. Verify compatibility with upstream circuit breakers and downstream loads when substituting.
