Product Overview

The 8720MC‑EF190‑VB is a complete pre‑wired EMC input filter accessory for Rockwell 8720MC‑RPS series regenerative power supply. It suppresses conducted EMI noise from mains side, mitigates harmonic distortion and transient voltage surges. Integrated main magnetic contactor implements safe power‑on pre‑charge sequence for DC‑bus capacitors. This unit is required hardware when system needs to meet CE EMC directive for 8720MC‑RPS190BM power frameRockwell A…. It connects between three‑phase AC mains and regenerative power supply, provides noise filtering and power switching function in one compact chassis.

This filter solves regenerative‑drive system challenges: all‑in‑one EMC+contactor+surge protection assembly for large‑capacity regenerative power unit, CE compliance hardware, drop‑in spare 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 test‑bench regenerative drive cabinets.

Key Application Notes

‑Accessory filter unit; cannot operate standalone. Must pair with 8720MC‑RPS190BM regenerative power supply; not compatible with other frame sizes (RPS065 etc)Rockwell A… ‑‑Original OEM production discontinued (end‑of‑sale July‑31‑2025); only aftermarket surplus/refurbished spare available ‑‑Not hot‑swap capable: three‑phase AC mains must be fully disconnected; DC‑bus capacitors require mandatory discharge waiting‑time before service work ‑‑Replacement spare must match full part‑number; different suffix variants have different internal contactor / filter ratings ‑‑Follow Rockwell 8720MC‑RPS official manual for pre‑charge sequence wiring and EMC‑compliant power‑cable requirements
