Uninterrupted power supply and reliability is essential for many critical power technologies as they depend on around-the-clock system availability for an array of applications. A momentary loss of power can shut down hospitals and first responder communication networks, financial institution computer hardware, air traffic control centers/towers, business-based infrastructures, and telecommunication systems. Because performance always matters, quality protection and control are essential. ABB can deliver UPSs manufacturers with a full range of low voltage products to achieve high-availability systems in terms of reliability, functionality, maintainability and fault tolerance.
