Allen Bradley 22-RFD150 PowerFlex EMC Line Filter

Product Overview

The Allen Bradley 22-RFD150 serves as a high-performance Electromagnetic Compatibility (EMC) filter specifically engineered for the PowerFlex series of Variable Frequency Drives (VFD). This 3-phase line filter suppresses electromagnetic interference (EMI) and radio frequency interference (RFI) generated by the drive's high-speed switching transistors. It ensures your automation system complies with international EMC standards and prevents high-frequency noise from disrupting sensitive nearby electronics, such as sensors and communication networks. We supply this unit as 100% Brand New and Factory Original, guaranteeing optimal attenuation performance and electrical safety.

Technical Specifications

The 22-RFD150 manages power quality across a broad range of high-capacity drive ratings:

Engineering Advantages

• Broadband Interference Suppression: The 22-RFD150 utilizes high-permeability magnetic cores to filter out conducted emissions. This hardware prevents noise from traveling back into the primary power grid, protecting PLC processors and I/O modules from erratic behavior caused by power line "pollution."

• High-Power Compatibility: This specific model supports heavy-duty applications, handling up to 55 kW (75 HP) loads at 480V. The robust internal capacitors and inductors withstand the thermal stress of continuous operation in high-torque manufacturing environments.

• Dual-Voltage Versatility: The filter's design accommodates both 240V and 480V systems. This allows engineering teams to standardize on a single filter part number for varied motor control centers, simplifying inventory management for global facilities.

• Critical Compliance Support: Installing the 22-RFD150 helps your machine meet CE and other regional EMC directives. It provides the necessary attenuation levels to pass rigorous electromagnetic susceptibility tests required for export-grade equipment.

• Low Leakage Current Profile: Optimized for industrial safety, the filter limits leakage current to ground. This reduces the risk of nuisance tripping in RCD-protected circuits (Residual Current Devices) while maintaining effective high-frequency noise diversion.

FAQs

• Is this 22-RFD150 unit 100% Brand New?

  Yes. We supply only 100% Brand New units in original Allen Bradley factory packaging. We do not sell used or refurbished filters, ensuring the internal dielectric components provide their full engineered service life without degradation.

• Where should I install this filter in my drive system?

  For maximum effectiveness, mount the 22-RFD150 as close to the drive's input power terminals as possible. Always use a flat, unpainted metal surface for mounting to ensure a low-impedance ground path, which is critical for diverting high-frequency noise away from the drive.

• Can I use one 22-RFD150 for multiple small drives?

  While technically possible if the total current draw stays within the rated limits (22–55kW equivalent), we recommend a dedicated filter for each drive to prevent cross-talk between VFDs. For the 22-RFD150, ensure the connected load matches the 30–75 HP application range for optimal performance.

• Does this filter require a specific type of cable?

  To achieve full EMC compliance, use shielded (armored) motor cables between the drive and the motor. The 22-RFD150 cleans the input power, but shielded cabling is necessary to contain radiated emissions on the output side.
