ABB offers an auxiliary power upgrade for its ACS 1000 medium voltage drive to further increase the drive's reliability and availability. This upgrade improves the reliability and availability of the ACS 1000, with longer auxiliary power loss ride through capabilities and easy troubleshooting.
The document explains a new auxiliary power concept for the ABB ACS 1000 drive that eliminates the backup batteries and uses a safe‑line UPS source. The retrofit improves reliability, provides easy troubleshooting via digital inputs, and reduces on‑site downtime.
It includes the old and new power‑supply configurations, required parts, ordering codes for air‑cooled and water‑cooled versions, and contact details for ABB service organizations.
| Backup battery ride‑through time | 1 second |
|---|---|
| Typical on‑site upgrade time | Approximately one working day |
| Auxiliary supply voltage (new concept) | 100 – 240 VAC SafeLine AC |
The upgrade typically requires approximately one working day on site.
Use 3BHB017534R0001 for air‑cooled ACS 1000 and 3BHBO17534R0002 for water‑cooled ACS 1000.
The original backup batteries provide a power‑loss ride‑through of one second.
