DPA UPScale ST

Commercial Uninterruptible Power Supplies

product catalog

ABB’s DPA UPScale ST is designed for high-density applications requiring an all-in-one power protection solution that integrates the UPS frame, batteries and communication interfaces.

The system delivers power protection from 10 kW to 200 kW in modular 10 kW or 20 kW increments. For continuously growing mid-sized infrastructures, multiple DPA UPScale ST systems can be connected in parallel to increase total capacity up to 400 kW.

This fully scalable and easily maintainable UPS solution provides exceptional uptime and energy efficiency.

The modular design of the DPA UPScale ST provides vertical scalability from 10 kW up to 200 kW (180 kW N+1) within a single cabinet, using 10 kW or 20 kW power modules.

For growing mid-sized infrastructures, multiple systems can be connected in parallel to increase total capacity up to 400 kW.

This ability to add power capacity as the critical load increases optimizes operating efficiency while reducing initial investment costs.

The DPA UPScale ST can be deployed in a wide variety of small- and medium-sized critical power environments.

In addition to traditional server applications, it is particularly well suited for protecting critical infrastructure such as Building Management Systems (BMS).

Modern facilities rely on BMS platforms to monitor and control mechanical and electrical systems including ventilation, lighting, fire alarm systems and security infrastructure.

These systems help maintain a safe, productive and comfortable environment, improve operational efficiency, reduce energy consumption and protect both personnel and equipment.

The DPA UPScale ST provides clean, reliable backup power for sensitive electronic devices such as controllers, I/O devices and user interfaces, ensuring continuous monitoring and control while preventing data loss and equipment damage.
