All-in-one modular 3-phase UPS, 10/20 kW modules, up to 200 kW per frame (400 kW parallel), DPA architecture, five frame sizes in a compact 550 mm width.
The ABB DPA UPScale ST is a modular, standalone three-phase UPS built on ABB’s decentralized parallel architecture. It combines the compact footprint of a tower with the high availability and scalability of a true modular system, making it ideal for small and medium data centers, healthcare sites, and critical commercial facilities.
Each module is a fully independent UPS, and capacity can be added in the field as the load grows — so you pay only for what you need today while retaining a clear upgrade path.
