FN5420-26-92-E0XXT

Overview

The Schaffner FN5420-26-92-E0XXT is a three-phase sine wave output filter designed for regenerative motor drives. It operates at a rated voltage of 500VAC and supports a current of 26A up to 60Hz. The unit features an IP00 protection rating and weighs approximately 9.5 kg. Operating temperatures range from -40°C to 70°C.

Feature Summary

• Converts inverter pulse-width modulated (PWM) output into a sinusoidal waveform to protect motor insulation.
• Designed specifically for use with regenerative motor drive systems.
• Provides electromagnetic compatibility filtering for three-phase power lines.

Applications

• Regenerative motor drive systems
• Industrial variable frequency drive installations requiring sine wave output
• Protection of electric motors from dv/dt stress

Procurement Notes

Verify the specific electrical ratings and physical dimensions against the official Schaffner datasheet before integration. Confirm that the 500VAC and 26A specifications align with your system requirements. Ensure the IP00 rating allows for appropriate enclosure mounting to meet environmental safety standards.

Selection Notes

Select this component when sinusoidal output is required rather than standard EMC filtering. Ensure the drive system voltage does not exceed 500VAC and the load current remains within the 26A limit. Consider the IP00 rating necessitates external housing for outdoor or harsh environments.

Part Context

This model belongs to the FN 5420 series of sine wave filters manufactured by Schaffner EMC Inc., now part of TE Connectivity. These filters are engineered to mitigate common mode voltages and reduce bearing currents in AC motor applications, extending equipment lifespan.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement maintains the 500VAC/26A rating and three-phase configuration. Verify thermal management requirements match the original design constraints.
