ABB offers an auxiliary power upgrade for its ACS 1000 medium voltage drive to further increase the drive's reliability and availability. The upgrade eliminates the need for internal backup batteries by using a safe line auxiliary source from the customer's UPS. This improves the reliability and availability of the ACS 1000.
The auxiliary power upgrade replaces the original battery‑backed supply with a safe‑line UPS source, improving reliability and availability of the ACS 1000 variable speed drive. The new concept eliminates the one‑second power‑loss‑ride‑through limitation of the backup batteries.
The upgrade includes two ready‑wired assemblies, an interface board jumper, and optional parts for air‑cooled or water‑cooled versions. It can be ordered from ABB service organizations using specific part codes, and the on‑site installation typically requires about one working day.
| Drive type | Variable speed drive |
|---|---|
| Cooling options | Water cooled and air cooled |
| Auxiliary supply voltage | 100 - 240 VAC SafeLine AC |
| Power‑Loss‑Ride‑Through | One second |

The upgrade typically requires approximately one working day on site.
Use 3BHB017534R0001 for the air‑cooled ACS 1000 and 3BHBO17534R0002 for the water‑cooled ACS 1000.
It uses a safe‑line auxiliary source from the customer's UPS to supply the drive power supplies.
