AMI-21B-20-3

Power Line Filter Modules Overview

The AMI-21B-20-3 is a single-phase EMI/EMC line filter from the Altran Magnetics AMI-21 series, designed for chassis mounting. It operates at a rated voltage of 250VAC and supports a current capacity of 20A. The unit functions within a frequency range of DC to 400Hz and utilizes a single-stage configuration with quick connect terminals.

Power Line Filter Modules Feature Summary

• Chassis mount design for rapid installation
• Single-stage filtering architecture
• Quick connect terminal interface

Power Line Filter Modules Applications

• General conducted emission suppression in AC-powered systems
• Medical equipment requiring Type B configurations without Y-capacitors
• Power supply input stages for electronic devices

Power Line Filter Modules Procurement Notes

Verify that the specific application requires the Type B variant, which lacks Y-capacitors, as this distinguishes it from standard versions. Confirm that the 20A current rating and 250VAC voltage specifications align with the system's electrical requirements. Ensure compatibility with the quick connect terminal style and chassis mounting method before finalizing procurement decisions.

Power Line Filter Modules Selection Notes

Select this component when a single-stage filter is sufficient for the required attenuation levels. The Type B designation indicates the absence of Y-capacitors, making it suitable for applications where leakage current must be minimized or specific medical safety standards are mandated. Verify that the physical dimensions accommodate the available chassis space.

Power Line Filter Modules Part Context

This part belongs to the AMI-21 series of single-phase filters manufactured by Altran Magnetics. The series includes various current ratings and configurations, such as Type A for low leakage and Type B for medical use. These filters are engineered for easy integration into power distribution systems requiring compact EMC solutions.

Power Line Filter Modules Replacement Considerations

Publicly confirmed substitute part numbers for the AMI-21B-20-3 are not available in the provided documentation. Cross-referencing should be performed carefully to ensure equivalent electrical ratings and mechanical form factors if an alternative is sought.
