B84143V0025R227

Power Line Filter Modules Overview

The B84143V0025R227 is a three-phase sine-wave output filter manufactured by EPCOS (TDK Electronics). It is designed for use with variable speed drives to convert PWM output into a sinusoidal voltage waveform. The component features a rated current of 25A and a rated voltage of 520V. It operates at frequencies of 50/60Hz and includes an IP21 housing for protection against solid objects larger than 12.5mm. The filter utilizes a single-stage delta configuration to mitigate high dv/dt stresses on motor insulation.

Power Line Filter Modules Feature Summary

• Converts pulse-width modulated drive output into a pure sine wave to protect motor insulation from high dv/dt stress.
• Features an integrated IP21 protective housing that prevents contact with live parts and ingress of large solid objects.
• Supports shielded motor cables via the Sineformer series design, allowing for longer cable runs without signal degradation.

Power Line Filter Modules Applications

• Variable frequency drive systems requiring sine-wave output filtering
• Industrial motor protection in environments with long cable runs
• Applications demanding reduced electromagnetic interference emission

Power Line Filter Modules Procurement Notes

Verify the specific suffix R227 corresponds to the required IP21 housing variant and terminal configuration. Confirm that the 25A current rating and 520V voltage rating align with the drive's continuous output specifications. Ensure the three-phase delta configuration matches the system topology before procurement.

Power Line Filter Modules Selection Notes

Select this model when sine-wave output is required rather than standard EMI suppression. The 25A rating suits medium-power industrial motors. Verify compatibility with shielded cables if using the Sineformer application context. Ensure the IP21 enclosure meets the installation environment's safety requirements.

Power Line Filter Modules Part Context

This component belongs to the B84143V* series of sine-wave output filters. Unlike standard line-side EMI filters, these are installed between the drive and the motor. The series is part of TDK EPCOS's broader portfolio of reactors and filters for drive applications, specifically targeting motor insulation protection.

Power Line Filter Modules Replacement Considerations

Public confirmed substitute part numbers were not identified in the provided documentation. Cross-referencing requires matching the 25A current, 520V voltage, and IP21 housing specifications exactly.
