MegaFlex DPA

Commercial Uninterruptible Power Supplies

product catalog

The online double-conversion MegaFlex DPA UPS provides premium power protection for critical infrastructure with capacities ranging from 250 kW to 1,500 kW.

This modular UPS is specifically designed for high-density computing environments, including private and public enterprise facilities, colocation and hosting data centers, cloud service providers and telecommunications applications.

The MegaFlex DPA UPS is built on ABB’s Decentralized Parallel Architecture (DPA™), where each power module operates as an independent UPS containing all critical functional components required for autonomous operation.

This architecture delivers full redundancy and fault tolerance, resulting in system reliability and availability that surpass conventional modular UPS designs.

Flexible approach

• Easily scalable solutions
• Up to 1,500 kW power protection in a single UPS through additional power modules
• Redundant configurations available: 1,000 kW N+1 and 1,250 kW N+1
• Collaborative, customer-focused system design

Optimized efficiency

• Reduced energy losses, heat generation and electricity costs in both double-conversion and ECO operating modes
• Intelligent load sharing optimizes energy consumption
• ABB Xtra VFI modes improve efficiency under low-load conditions
• High efficiency maintained throughout the product’s 15-year design life

Reliable operations

• DPA™ technology maximizes system availability
• Online-swappable power modules ensure continuous uptime
• Automatic isolation of faulty power modules
• Fault-tolerant UPS architecture for uninterrupted power protection
• Local and remote real-time monitoring for simplified operation

Simple installation and serviceability

• Plug-in power modules provide safe and simple connections
• Pre-engineered power frames eliminate the need for internal wiring
• Cleans and conditions incoming power
• Automatic self-configuration and testing minimize human intervention

As power requirements grow, the MegaFlex DPA UPS can expand alongside the infrastructure.

With 3–4 power frame slots and connection frames available in 1 MW and 1.5 MW configurations, the system offers a flexible mechanical layout that supports both current requirements and future expansion.

• Easily scalable modular architecture
• Capacity can be optimized to match varying load levels
• Straightforward upgrades for increasing power demands
• User-friendly operation for facility personnel
• Simplified maintenance procedures
  
• Parallel operation of up to four systems

Maintenance made easy

The modular design of the MegaFlex DPA UPS has been engineered to simplify maintenance while reducing the likelihood of human error.

Module cabinets can be transported easily and inserted directly into the UPS frame using integrated wheels.

Docking connectors eliminate the risk of cabling errors during installation, while front and rear cable access points within the IP20-protected cabinet provide safe and convenient power connections.

The cooling fan assembly is mounted on a pull-out drawer for easy servicing and includes integrated failure detection and automatic speed regulation.

In energy-intensive facilities, even small efficiency gains can generate substantial cost savings and reduce CO₂ emissions.

The MegaFlex DPA UPS combines industry-leading efficiency with a highly compact footprint.

• VFI double-conversion efficiency of up to 97.4%
• VFD ECO mode efficiency of up to 99.4%
• Up to 45% footprint reduction through ultra-high power density (kW/m²)
• Optimized efficiency during partial-load operation
• Lower operating costs and reduced environmental impact throughout the system lifecycle
