Higher efficiency. Independent backup.
Seamless power continuity for the
next generation of Al infrastructure.
For decades, dual UPS systems have been the standard approach for mission-critical facilities. While they provide redundancy, both power paths rely on the same technology and follow nearly identical power conversion processes.
As AI data centers continue to demand higher efficiency, greater power density, and lower operating costs, conventional architectures introduce several limitations.
Power is repeatedly converted between AC and DC, reducing overall system efficiency.
Two identical UPS systems may share similar hardware, software, and control architectures, increasing the possibility of common failure mechanisms.
Two identical UPS systems may share similar hardware, software, and control architectures, increasing the possibility of common failure mechanisms.
Traditional low-voltage AC distribution becomes increasingly challenging as rack power density continues to grow.
Instead of relying on two identical UPS systems, ETAC combines two fundamentally different power technologies into one integrated architecture.
The SST branch serves as the primary high-efficiency power path, while the UPS branch remains fully energized as an independent backup system.
Both power paths are connected through a DC Static Transfer Switch (DC STS), allowing seamless transfer without interrupting critical IT operations.

The SST branch eliminates multiple AC/DC conversion stages found in traditional UPS architectures, reducing energy losses and improving overall efficiency.
Because SST and UPS use fundamentally different technologies, failures affecting one system are unlikely to impact the other.
Higher efficiency translates directly into reduced electricity consumption and lower cooling requirements throughout the facility lifecycle.
Native support for 800VDC distribution enables higher rack power density and prepares facilities for next-generation AI computing platforms.
High-speed DC STS technology provides uninterrupted power transfer during equipment faults or planned maintenance.
ETAC provides complete engineering support and equipment supply for hybrid power systems, including:
Designed to support a wide range of mission-critical power applications across modern industries.
Whether you’re designing a new AI data center or upgrading an existing facility, ETAC can help you implement a more efficient, more reliable, and future-ready power architecture.
