Overview
The Astrodyne TDI SX20 is a single-phase, three-stage power line filter rated for 250V AC and 20A. It provides high-performance EMI/RFI suppression in a compact chassis-mount design. The unit features quick-connect terminals for rapid installation and meets UL, CSA, and EN safety standards. Operating within a temperature range of -25°C to +40°C, it ensures reliable noise attenuation for sensitive electronic equipment in industrial and commercial environments.
Feature Summary
- Three-stage filtering architecture for enhanced noise suppression
- Compact chassis-mount design with quick-connect terminals
- Compliant with UL, CSA, and EN safety regulations
Applications
- Industrial control systems requiring EMI protection
- Medical equipment power inputs
- Commercial IT infrastructure power distribution
Procurement Notes
Verify the specific terminal configuration and capacitance value against your system requirements before ordering. Confirm that the 250V AC rating and 20A current capacity align with your load specifications. Ensure chassis mounting provisions match your enclosure design. Check for any specific environmental constraints regarding the operating temperature range.
Selection Notes
Select this model when high attenuation is required in a limited space. The three-stage design offers superior performance compared to single or two-stage alternatives. Ensure the input voltage does not exceed 250V AC. Verify that the 20A continuous current rating suits the connected load. Consider the chassis-mount style for fixed installations rather than PCB mounting.
Part Context
The SX20 belongs to Astrodyne TDI's power line filter portfolio, designed for robust EMI/RFI mitigation. It complements other series like RP225 by offering a three-stage configuration in a similar form factor. This component addresses stringent EMC requirements in applications where noise immunity is critical for operational stability and regulatory compliance.
Replacement Considerations
Direct substitutes may include other three-stage, 20A, 250V AC filters from Astrodyne TDI or compatible manufacturers. Verify pinout compatibility and mounting dimensions. Ensure equivalent leakage current and capacitance values to maintain circuit safety and performance. Cross-reference datasheets for exact electrical parameter matching.
