Description

PFPL203 3BSE055365R1: Product Overview
This power line filter is designed for integration into industrial automation systems, serving as a critical component for power quality management in distributed control system (DCS), programmable logic controller (PLC), and safety instrumented system (SIS) architectures. Its role is to condition incoming AC power by attenuating conducted and radiated electromagnetic interference (EMI/RFI), thereby protecting sensitive downstream electronics—such as controllers, I/O modules, and communication interfaces—from voltage fluctuations and noise.
The core functionality involves filtering harmonic distortion, suppressing transient spikes, and stabilizing voltage levels. It handles 3-phase AC power inputs, targeting frequencies from 150 kHz to 30 MHz where industrial equipment (e.g., variable frequency drives, welders) typically generates interference. As part of ABB’s Advant Power Management series, the filter benefits from a platform optimized for compatibility with ABB automation hardware, ensuring seamless integration and adherence to global electromagnetic compatibility (EMC) standards. The series is valued for its modularity, allowing it to be deployed in diverse environments without requiring custom power conditioning solutions.

Core Features & Customer Value​
High insertion loss for EMI/RFI suppression: The filter achieves over 60dB attenuation in the critical 150kHz–30MHz range, effectively reducing interference from adjacent machinery. For engineers, this minimizes erratic behavior in PLC logic or DCS communication, which is often caused by noisy power supplies, and reduces troubleshooting time spent diagnosing intermittent faults.
Wide input voltage tolerance: Supporting 380-480V AC 3-phase input, the unit adapts to regional grid variations and minor voltage sags without additional transformers. This eliminates the need for voltage regulators in many applications, lowering system cost and complexity.
Compact panel-mount design: With dimensions of 200x150x100mm, the filter occupies minimal space in control cabinets. For procurement managers, this is advantageous in retrofit projects where cabinet real estate is limited, avoiding costly cabinet expansions.
Compliance with industrial EMC standards: Certification to IEC 61800-3 and CE/UL ensures the filter meets global regulatory requirements for industrial equipment. This simplifies compliance audits and reduces the risk of project delays due to non-conforming components.
Ruggedized construction for harsh environments: Operating reliably from -25°C to +70°C, the filter withstands temperature extremes in outdoor substations or unconditioned control rooms. Its sealed enclosure protects against dust and moisture, extending service life in demanding settings like steel mills or chemical plants.
Typical Applications​
The filter is deployed in scenarios where clean power is critical to automation system stability. In a natural gas processing plant, it is installed at the incoming power feed to a DCS rack, protecting redundant controller pairs from interference generated by nearby reciprocating compressors. This ensures continuous monitoring of separation and dehydration processes.
In an automotive assembly line, the unit conditions power for a PLC-controlled robotic welding station. By filtering EMI from welding equipment, it prevents glitches in robot trajectory commands, maintaining weld quality and reducing scrap.
Another application is in a municipal water treatment facility, where it safeguards SIS logic solvers that trigger emergency shutdowns. Here, stable power prevents nuisance trips caused by transient noise from variable speed pumps, ensuring safety systems respond only to genuine process anomalies.
