Product Overview

The 8720MC‑EF190‑VB is a complete pre‑wired EMC input filter accessory for Rockwell 8720MC‑RPS190BM regenerative power supply unitRockwell A…. It suppresses conducted EMI noise from AC mains side, mitigates harmonic distortion and absorbs transient voltage surges. The built‑in magnetic contactor executes safe pre‑charge sequence for DC‑bus capacitors. This hardware is required to meet CE EMC directive when deploying 8720MC‑RPS190BM regenerative power frame. Installed between three‑phase AC mains and regenerative power supply, it combines noise filtering and safe power switching within one metal chassis.

This filter addresses regenerative motion‑system challenges: all‑in‑one EMC + contactor + surge‑protection assembly for high‑current regenerative power unit, CE compliance hardware, drop‑in spare‑part compatibility for legacy 8720MC‑series retrofit‑maintenance projects. Motion‑control engineers, plant‑maintenance technicians and retrofit integrators benefit most. Typical applications: heavy‑duty multi‑axis servo systems, metal‑forming presses, large‑capacity test‑bench regenerative drive cabinets.

Key Application Notes

‑Accessory filter unit; cannot operate standalone. Must pair exclusively with 8720MC‑RPS190BM regenerative power supply, cannot cross‑use with RPS065 frame variantsRockwell A… ‑Lifecycle status: End‑of‑sale since July‑31‑2025; only aftermarket surplus / refurbished spare parts availableRockwell A… ‑Not hot‑swap capable: Disconnect three‑phase AC mains completely; observe mandatory DC‑bus capacitor discharge waiting‑time before any service work ‑Full part‑number matching is required for replacement; different suffix variants have different contactor and filter ratings ‑Follow Rockwell 8720MC‑RPS hardware manual for pre‑charge sequence wiring and EMC‑compliant power‑cable installation rules
