High-Availability Power Systems, Part II: Redundancy Options

From Emerson Network Power / Liebert Power & Cooling
 

 

"High-Availability" power systems require Reliability, Functionality, Maintainability, and Fault Tolerance. A few UPS configurations can overcome the "Last Four Hours" problem to achieve Continuous Availability of conditioned power. These configurations also greatly improve the power systems' fault tolerance, as we shall see.

Products & Services
Power strips are used in applications where multiple AC outlets are needed, often without surge or line noise protection. Search by Specification | Learn more about Power Strips
Single phase uninterruptible power supplies (UPS) sit between an AC outlet and an electronic device to provide power conditioning, back-up protection, and distribution for electronic equipment loads. They also prevent power disturbances from affecting the performance and life of the electronic device and vital data.  Search by Specification | Learn more about Single Phase Uninterruptible Power Supplies (UPS)
Three phase uninterruptible power supplies (UPS) operate in conjunction with existing electrical systems to provide power conditioning, back-up protection, and distribution for electronic equipment loads that use three-phase power.  Search by Specification | Learn more about Three Phase Uninterruptible Power Supplies (UPS)
Power or line conditioners regulate, filter, and suppress noise in AC power for sensitive computer and other solid state equipment. Search by Specification | Learn more about Power Conditioners
Uninterruptible power supplies (UPS) are backup batteries that provide emergency power to electrical systems in case power becomes unavailable. They are connected between a power source (such as an electrical outlet) and the equipment to protect (such as a motor or computer).
