🔋 Product Overview
The ABB DPA UPScale ST / RT is a Modular Online Double Conversion UPS system engineered for high availability, redundancy, and energy efficiency. With power scalability from 10 kW to 200 kW, and flexible rack (RT) or tower (ST) form factors, it’s ideal for mid-sized data centers, medical facilities, financial institutions, and industrial environments requiring uninterrupted power and zero downtime.
Built on ABB’s Decentralized Parallel Architecture (DPA™), each UPS module operates independently—offering true N+1 or N+X redundancy, minimizing single points of failure, and enabling hot-swappable servicing with zero system interruption.
