RP188-3-1-QD

Overview

The Astrodyne TDI RP188-3-1-QD is a single-stage power line filter module designed for 1-phase applications. It features a rated current of 3 A and a capacitance of 1 nF, operating at standard frequencies of 50 Hz and 60 Hz with a voltage rating of 250 VAC. The unit utilizes a PEM (Power Entry Module) configuration incorporating an IEC inlet, integrated fuse, and switch. Physical dimensions are approximately 73.5 mm in length, 34 mm in width, and 67.4 mm in height. Leakage current specifications vary by configuration, citing values such as 340 µA and 190 µA.

Feature Summary

• Integrated Power Entry Module design combining filtering with IEC inlet connectivity
• Built-in safety fuse and operational switch for direct equipment integration
• Single-stage EMI attenuation architecture optimized for compact form factors

Applications

• Medical equipment requiring certified power entry solutions
• Industrial control systems needing integrated switching and filtering
• Test and measurement instruments demanding low leakage current

Procurement Notes

Verify specific certification requirements against the official datasheet before procurement. Confirm exact leakage current ratings and physical mounting constraints for your chassis design. Ensure compatibility with local electrical codes regarding integrated fuses and switches. Check current availability status as supply may be limited or subject to backorder conditions.

Selection Notes

Select this model when space constraints preclude separate filter and connector assemblies. The integrated fuse and switch simplify panel cutouts and wiring. Verify that the 3 A current rating meets peak load demands. Consider the single-stage performance limits if higher attenuation is required compared to dual-stage alternatives.

Part Context

This component belongs to the RP188 series of Power Line Filter Modules from Astrodyne TDI. The series focuses on compact, all-in-one power entry solutions that merge filtering capabilities with standard IEC connectors and safety switches. This approach reduces assembly complexity and saves valuable board or chassis real estate in sensitive electronic applications.
