June 23, 2026 • 3 min read • wayne • Guide

Product Summary

The 22F-RF012-BS is a factory-matched EMC filter kit for PowerFlex 4M drives. This unit operates on a 480V, 50/60 Hz, three-phase power supply. It supports motors rated between 2.2 and 3.7 kW. Engineers use this filter to reduce electromagnetic interference. The short cable length design ensures a compact installation footprint.

Expert Technical Evaluation & Performance Review

Key Electrical Specifications

The 22F-RF012-BS delivers reliable noise suppression for industrial networks. It handles a line voltage of 380 to 480V AC across three phases. The unit supports a continuous current rating of 12 Amps. This rating perfectly matches 2.2 to 3.7 kW drive applications. The filter operates efficiently at both 50 and 60 Hz frequencies.

Mechanical Dimensions and Weight

This EMC filter kit features a compact B Frame design. The total unit weight is only 1.37 kg for easy handling. Its physical dimensions measure 15.60 mm in width. The height stands at 7.70 mm with a depth of 27.51 mm. These small dimensions allow installation inside tight control panels.

Compliance and Compatibility

The 22F-RF012-BS integrates directly with PowerFlex 4M adjustable frequency drives. This filter kit meets strict European EMC directives for conducted emissions. It specifically reduces high-frequency noise on the input power lines. The short cable length version optimizes performance for minimal wiring runs. This design prevents radiated interference from long motor cables.

Installation Requirements for Engineers

Technicians must mount this filter near the drive input terminals. The kit requires a solid earth ground connection for proper operation. Installers should use shielded cable for all motor wiring. The filter reduces electrical noise back onto the main power grid. This action protects sensitive equipment like sensors and PLCs.

Comparative Advantage Over Unfiltered Drives

A PowerFlex 4M without this filter radiates significant electromagnetic noise. This noise can disrupt communication networks and control signals. The 22F-RF012-BS actively suppresses that interference at the source. It ensures compliance with global EMC standards for industrial machinery. This protection prevents costly production downtime and data errors.

Procurement Considerations for Buyers

Verify your drive model number before purchasing this filter kit. The 22F-RF012-BS fits only specific PowerFlex 4M frame sizes. Confirm your motor power rating falls within the 2.2 to 3.7 kW range. This filter supports short cable lengths only, not long cable runs. Always check the voltage configuration of your existing drive system.
