 Uninterruptible Power Supplies; a Simple Guide to LocationSuccessful uninterruptible power supply installation can mean the difference between maintaining and losing business continuity. As so often in business, choosing the right UPS location takes good planning, a clear understanding of power protection objectives, the best possible uninterruptible power supply for the budget, and professional installation. Centralised V Distributed Uninterruptible Power Supplies (ups)Anyone working in data centre or mainstream computing environments will be familiar with the terms ‘distributed’ and ‘centralized’ computing and the advantages and disadvantages of each for specific applications. For small to mid-sized computer rooms, the choice between centralised and distributed Uninterruptible Power Supplies (UPS) holds similar considerations. Sizing Uninterruptible Power Supplies for Energy EfficiencySizing an uninterruptible power supply is more than simple math. Done badly, it can be costly. On the one hand, oversizing can add to installation and running costs. On the other, under-sizing will lead to dangerous overload situations. So, how do you correctly size a UPS system? This article explains. Ups Maintenance ContractsIf you want something mechanical or electrical to keep working it requires regular maintenance. Uninterruptible power supplies are no different. Users rely on them when mains power fails but often fail to maintain them. This article outlines the importance of regular UPS maintenance and highlights what should be included in a maintenance contract. Energy Efficiency in Uninterruptible Power Supply DesignEnergy efficiency in uninterruptible power supply design is now more important than ever. This is particularly true for datacentres where the need to protect ever more power-hungry equipment is as critical as the need to cut costs. This article touches on the different approaches taken to energy efficiency in the datacentre and the hidden vulnerabilities of some of the more radical ones. Ups Batteries – Taken for Granted Too Long!UPS batteries play a vital - and often taken-for-granted - role in the correct operation of an uninterruptible power supply and the continuity of protected loads. Despite the importance of UPS batteries for providing runtime and dc supply to the inverter in the event of mains failure, routine checks and maintenance are easily and often overlooked, which is not good practice. Choosing Between Different Types of Uninterruptible Power SupplyUninterruptible power supply is becoming increasingly important as business managers struggle with the reality that mains electricity may not be reliable enough to support today's dynamic business environments. But what is a UPS and what's the difference between one and the next? This article outlines the basics: Choosing a Ups Provider is About More Than Just HardwareThe relationship you have with your UPS provider can be as critical to the success of your installation as the hardware itself. Choose the right provider and you could be in for a smooth ride towards cost-effective power protection. Choose the wrong one and the cost could be high in terms of both investment and reputation. Business Continuity V Power ContinuityBusiness continuity has scaled the heights of the boardroom agenda at corporates throughout the world. Causes of operational disruption can be many and various but thankfully most are rare occurances. One, however, is happening with increasing frequency; power cuts or outages are occuring more often than ever as the world struggles with being on the brink of an energy crisis. So, shouldn't power continuity be the central theme of a business continuty policy rather than merely an item? Power Quality, Problems & SolutionsBusinesses and organisations are now totally dependent on electricity to run their data and voice processing systems. Power failures - short or long - can be devastating if they are not protected by UPS (uninterruptible power supplies).
However, a lesser-known threat - but equally troublesome - is that of power quality and problems in supply.
