ABB SRFC4620C – Inverter Filter Plate | EMC/RFI Suppression | ACS800 Series Platform
Engineering Background
The SRFC4620C is an OEM-specified inverter filter plate engineered by ABB for integration within the ACS800 series variable frequency drive (VFD) platform. Designed to attenuate conducted electromagnetic interference (EMI) and radio-frequency interference (RFI) at the inverter output stage, this component is a critical element in achieving compliance with IEC/EN 61800-3 Category C2/C3 emission standards in industrial drive installations.
Product Positioning
Targeted at procurement engineers and maintenance teams responsible for ACS800 drive systems in process automation, material handling, HVAC, and heavy industry, the SRFC4620C provides a direct OEM replacement path without the need for third-party filter adaptation. Konmask.com supplies this component with full traceability documentation, supporting both MRO (maintenance, repair, and operations) and new-build project procurement.

System Architecture & Signal Flow
Within the ACS800 drive architecture, the SRFC4620C filter plate is positioned at the inverter output stage, between the IGBT power module assembly and the motor cable terminals. Its primary function is to suppress high-frequency common-mode and differential-mode noise generated by PWM switching transitions, preventing conducted emissions from propagating onto motor cables and into the facility power network. The filter plate integrates with the drive’s internal bus structure and grounding scheme, ensuring low-impedance EMC bonding consistent with ABB’s drive system design.
