The Different Types of UPS Systems 0000-00-00 American Power Conversion (APC)

There is much confusion in the marketplace about the different types of UPS systems and their characteristics. Each of these UPS types is defined, practical applications of each are discussed, and advantages and disadvantages are listed. With this information, an educated decision can be made as to the appropriate UPS topology for a given need.

Calculating Total Cooling Requirements for Data Centers 20041029030001 APC

All electrical equipment produces heat, which must be removed to prevent the equipment temperature from rising to an unacceptable level. Most Information Technology equipment and other equipment found in a data center or network room is air-cooled. Sizing a cooling system requires an understanding of the amount of heat produced by the equipment contained in the enclosed space, along with the heat produced by the other heat sources typically encountered. This document describes how to estimate heat output from Information Technology equipment and other devices in a data center such as UPS, for purposes of sizing air conditioning systems. A number of common conversion factors and design guideline values are also included.

Monitoring Redundant Uninterruptible Power Supplies Using IBM Director 20040924030001 IBM

Most UPS monitoring software assumes the server is communicating directly with, and getting power from, only one UPS. Larger UPSes have multiple communication ports or network ports to allow multiple servers to monitor the state of the UPS. This paper will discuss and demonstrate using IBM Director to monitor UPSes in this environment. It also covers the ability of IBM Director to shut down the appropriate systems, when necessary.

Power interruptions can cause severe repercussions for business computer systems. The problem is especially difficult in places where power outages and fluctuations frequently occur. A UPS provides a backup battery and power inverter circuitry to insulate systems and data from power outages. In situations where momentary power fluctuations occur, a UPS provides constant power to keep your systems running. During extended power failures, a UPS provides backup power to keep your computers running long enough so that you can gracefully power down.

UPS Technologies: Take Your Pick - What is a UPS? 20040302121452 MGE UPS Systems

Electricity suppliers distribute what is known as alternating current (AC), at a voltage of 230 volts and a frequency of 50 Hertz. The only way of storing electricity, in a battery for example, is to convert the alternating current from the mains power supply into what is known as direct current (DC). Simply speaking, a UPS is a buffer-battery located between the power socket and the computer. It converts the AC mains power supply into direct current in order to charge the battery and then reconverts it back (to AC) in order to supply the load, in this case a computer.
